November 12, 2026 | Daily Amine Industry Briefing | Specialty Amine Catalysts, Chiral Routes and a Split Price Board

This edition follows the amine value chain from the PU China 2026 exhibition floor to epoxy-derivative strategy, chiral synthesis papers, and the price and investment disclosures dated 11 and 12 November 2026. Four items are drawn from material published today and yesterday, with the newest corporate filings dated today. Supplier advertisements, promotional product listings, quotation pages, telephone numbers, instant-messaging contacts and QR codes have been excluded, and source names are given as plain text rather than promotional links.

1. Specialty Amine Catalysts and Chain Extenders Take Centre Stage at PU China 2026

1. Summary: Reporting on the 22nd China International Polyurethane Exhibition (PU China 2026, Shanghai, 3–5 November) published on 11 November frames the industry as leaving scale expansion behind for raw-material innovation, emerging applications and full-chain green transition. Meiside Chemical chairman Sun Yu said high-end additives remain in short supply despite ample mid- and low-end capacity, and launched ultra-low-conductivity rigid-foam and compression-resistant flexible-foam silicone stabilisers for cold-chain insulation and exported compressed mattresses. Xiangyuan New Materials chairman Zhou Jian urged co-compounding with downstream processors and full-chain validation; the company showed an HMDEA chain extender for high-transparency energy-storage protective films in electronics and photovoltaics. Most directly relevant to nitrogen chemistry, Conch Hengguang exhibited ZF10 and other new specialty amine catalysts described as supporting domestic mass production of high-end specialty polyurethane and filling a domestic technology gap. A separate show report records Evonik pairing TEGOSTAB silicone surfactants with DABCO and POLYCAT amine catalysts for rigid foam, plus global debuts of TEGOSTAB B 8273 with ORTEGOL 700 and B 8292 for viscoelastic and moulded MDI foam; Covestro introduced the Desmodur 15 R prepolymer series and a Baulé casting machine for the Vulkollan process, with no grade-level NCO data disclosed. The industry association also lists BASF's low-emission Lupragen BisDMAPU (CAS 52338-87-1) flexible-foam catalyst from September 2026. With HCFC-141b fully phased out this year, HFO, HFC-245fa and all-water blowing systems are forcing catalyst packages to be re-qualified.

3. Editor's Pick + Reason: ZF10 and HMDEA being tied to named end-use specifications rather than generic performance claims. Reason: A domestic catalyst described as closing a specific technology gap, and a chain extender defined by a high-transparency film application, are both auditable qualification targets. They show where margin is moving in a market whose commodity segment is oversupplied, and they explain why suppliers are investing in joint downstream validation instead of competing on tonnage.

2. Epoxy Derivatives Forum Puts Ethanolamines and High-Purity Grades on the Agenda

1. Summary: The 2026 Epoxy and Derivatives Sustainable Development Cooperation Forum (Sanjiang Chemical) convened in Jiaxing, Zhejiang, on 5–6 November; the full account was published on 11 November. Yang Bin, deputy secretary-general of the national forum, described phased overcapacity in commodity epoxy base products and intensifying homogeneous competition, noting that a short-term price rebound is unlikely to reverse structurally low margins. His recommendations were to invest rationally and avoid inefficient new capacity, treat export growth as a key lever, cut cost across the whole chain, protect downstream polycarboxylate superplasticiser monomer supply, and push nonionic surfactants, ethanolamines and polyether polyols toward high-end refinement. Executive chairman Gu Qichang said the sector is shifting from scale expansion to structural upgrading: high-end polyethers and specialty alcohol ether esters have advanced, but pharmaceutical-grade, electronic-grade and narrow-distribution ethoxylates remain gaps requiring joint industry–academia work. Zheng Baoshan, vice president of the China National Petroleum and Chemical Planning Institute, argued for integrated chains, low-cost feedstocks and alternative process routes, higher value-added downstream products, faster industrialisation of missing grades and relief of key raw-material bottlenecks. Sanjiang Chemical founder Guan Jianzhong described clearing inefficient capacity, energy-saving retrofits and a deliberate move into green surfactants and electronic-grade fine chemicals. For curing packages this matters directly: imidazole-family accelerators such as 2-methylimidazole (CAS 693-98-1) remain standard mid-temperature epoxy curing agents and promoters for electronic encapsulation, powder coatings and composites, while doubling as intermediates for nitroimidazole pharmaceuticals. A shift toward electronic-grade, narrow-distribution derivatives therefore tightens ionic-impurity and consistency requirements on the nitrogen-heterocycle side of the formulation, not just on the resin.

3. Editor's Pick + Reason: The explicit naming of pharmaceutical-grade, electronic-grade and narrow-distribution ethoxylates as unresolved gaps. Reason: It converts a vague "high-end" narrative into three measurable qualification targets for ethanolamine and curing-agent producers. Combined with the call to expand exports and the admission of commodity overcapacity, it tells suppliers exactly which specifications justify capital spending and which volumes do not.

3. A Cluster of Chiral Amine Synthesis Results Reshapes Pharmaceutical Route Design

1. Summary: Several results published or reported in the last few days converge on making nitrogen-bearing stereocentres cheaper to build. Lanzhou University reports an in-situ Mg(II)/hydrogen-bond cooperative catalyst built on a new trihydroxy chiral ligand (JACS, doi.org/10.1021/jacs.6c16713). Amine/ketone pairing through iminium ions or hydrogen bonds has long blocked asymmetric aza-conjugate addition and caused product racemisation. The Mg(II) system suppresses that background pathway and delivers one-pot chiral gamma-amino alcohols with tertiary or quaternary stereocentres, with DFT support; the authors call the pattern transferable to chiral N-heterocycles and pharmaceutical intermediates. SUSTech's Shu Wei group published a nickel-catalysed regio- and enantioselective reductive homologation of enamines with alkynes in Nature Synthesis (doi.org/10.1038/s44160-026-01172-8), a cascade that builds a Csp3–Csp2 bond to give chiral allylic amines and was applied to drug intermediates. A second Nature Synthesis paper (doi.org/10.1038/s44160-026-01205-2, Maud T. H. Tregear and co-workers) replaces the classical Mitsunobu reagent set with an iminophosphorane generated in one to five minutes from 1-azido-4-methoxybenzene and tri-n-butylphosphine in toluene at 70 °C. It forms C–O, C–N, C–S and, importantly, C–C bonds beyond the traditional pKa ceiling near 11; tri-n-butylphosphine oxide is water-washed out and p-anisidine acid-washed and recycled, eliminating explosive DEAD and chromatographic cleanup. Model esterification reached 88% yield at two equivalents of the azide against 1% for triphenylphosphine. Westlake University's Deng Li team reported on 10 November a cinchona-derived bis-quaternary ammonium catalyst for precise asymmetric SN2 substitution. An engineered amine dehydrogenase (L40T/L125R/V291A) resolves the mirogabalin ketone intermediate to 97.1% ee and 45.4% yield by aminating only the unwanted enantiomer into a water-soluble ammonium salt, while a Nature photoredox-cobalt method performs late-stage N-methyl-selective C–H vinylation of unactivated trialkylamines with alkynes.

3. Editor's Pick + Reason: The iminophosphorane Mitsunobu replacement and its water-wash workup. Reason: It removes an explosive reagent and a chromatography step from routine C–N bond formation, which are process-scale cost and safety items rather than laboratory conveniences. The 88% versus 1% phosphine comparison and the demonstrated scale-up and late-stage functionalisation make it the most immediately transferable result for custom synthesis and pharmaceutical intermediate suppliers.

4. A Divided Amine Price Board and Fresh Capital Filings Point to Specification-Driven Demand

1. Summary: The 11 November bulk-chemical price board from 100ppi shows no single "amine market" trend. Quotes were unchanged on the day, but the accompanying period-change column splits sharply: dimethylethanolamine at 15,650 yuan/t (+5.03%) and diethanolamine at 8,300 yuan/t (+13.41%) sit alongside diethylamine at 11,100 yuan/t (−5.13%), diisopropylamine at 23,100 yuan/t (−8.27%), di-n-butylamine at 15,500 yuan/t (−4.12%), tert-butylamine at 32,333 yuan/t (−2.02%), triethylenetetramine at 51,900 yuan/t (−14.74%), dicyandiamide at 10,667 yuan/t (−2.74%) and o-toluidine at 15,600 yuan/t (−6.02%). Ethanolamines are firming while ethyleneamines and lower alkylamines soften, so grade mix and captive feedstock matter more than headline volume. A Shanghai Chemical Industry Park notice dated 11 November lists the first batch of 2026 development funding: its innovation-source category includes Shanghai Jieda Nylon Materials' process R&D on high-quality hexamethylenediamine and 2-methylpentanediamine; green low-carbon projects cover Evonik, Invista, Huntsman, BASF and Secco. Among filings dated today, Satellite Chemical announced a propylene and downstream high-end new materials investment framed as C2/C3 chain synergy at Lianyungang — upstream feedstock context, with no nitrogen-containing grades named. Zhejiang Xinnong Chemical reported slower phase-one progress on its 20,000 t/y green formulation project after optimising its product scheme and process route. In oil and gas, 2026 field guidance still specifies film-forming amines, imidazolines, quaternary ammonium salts and refinery-overhead neutralising amines against verified corrosion-rate targets rather than dosage claims.

Contact details in the original notice were not reproduced.

3. Editor's Pick + Reason: The divergence between diethanolamine at +13.41% and triethylenetetramine at −14.74% on the same price board. Reason: It disproves any single narrative about amine pricing and gives procurement teams a concrete split to work with: alkanolamine tightness coexists with ethyleneamine weakness. Paired with public funding for diamine process R&D, it confirms that policy and margin are concentrating on specified, qualified nitrogen products rather than commodity capacity.
