November 12, 2026 | Daily Amine Industry Briefing | Epoxy Costs, Pharmaceutical Nitrogen, Dimethylamine Chains and Low-Energy Capture Solvents — Second Edition

This second edition contains only material that surfaced after our morning briefing, so nothing here repeats that edition. It follows the amine value chain through today's epoxy cost signal, pharmaceutical registration and GMP milestones published yesterday, the dimethylamine-to-DMF chain in a market note issued today, and fresh engineering results on low-energy capture solvents and oilfield inhibitor films. The four items come from sources dated 11 and 12 November 2026. Supplier advertisements, promotional product listings, quotation pages, telephone numbers, instant-messaging contacts and QR codes have been excluded; source names appear as plain text rather than promotional links.

1. Epoxy Costs Soften on 12 November, Shifting Attention to Amine Curing Packages

1. Summary: Mysteel's epoxy resin morning note issued today reads bearish. Falling bisphenol A and epichlorohydrin prices have weakened cost support, new downstream orders are limited, and factory quotations are loosening while buyers purchase only against immediate need; the house view is a weak, declining market. One counter-current is crude: with Middle East tensions unresolved and the outlook for US–Iran talks unclear, ICE Brent front-month settled at 92.76 dollars per barrel, up 1.27 dollars or 1.39 percent. Regional liquid resin quotes from 11 November show the split: Northeast China at 15,300–15,500 yuan per tonne ex-works on a net-water basis was nominally stable but thinly traded, South China at 15,500–15,700 yuan per tonne was range-bound with rising wait-and-see behaviour, and the E-51 benchmark slipped 50 yuan to 15,300 yuan per tonne on a board updated today. For nitrogen chemistry the implication is indirect but concrete: when base resin becomes a price-taken commodity, formulators defend margin through the curing package. The established families are phenolic-modified amines and modified aliphatic amines for ambient-cure anticorrosion coatings, polyamide and amidoamine hardeners for toughness and pot life, and imidazole accelerators such as 2-methylimidazole plus strong amidine bases such as DBU for mid-temperature and latent systems in encapsulation, powder coatings and composites. DABCO-type tertiary amines double as epoxy accelerators and polyurethane blow/gel catalysts. Purchasing attention therefore shifts from resin tonnage to amine value, viscosity, colour and pot-life consistency.

Supplier catalogue and quotation pages were discarded.

3. Editor's Pick + Reason: The divergence between a 50 yuan decline in E-51 and the unchanged qualification burden on curing agents. Reason: It tells hardener producers where the negotiation will happen. When resin cost support collapses, buyers cannot extract much more from the base resin, so the auditable differentiators become amine value, pot life, colour stability and low-temperature cure. That is a specification argument, not a volume argument, and it is the one most likely to protect margin in a weak market.

2. Three Pharmaceutical Milestones Show Nitrogen Value Sitting in Compliance, Not Tonnage

1. Summary: Three disclosures dated 11 November illustrate how nitrogen-containing pharmaceutical products are priced on regulatory status. Heilongjiang Zhenbaodao Pharmaceutical's Jixi branch received a chemical API marketing authorisation approval notice for baloxavir marboxil, a substituted nitrogen-heterocycle antiviral used against influenza A and B as tablets and as a paediatric dry suspension. The notice runs to 4 November 2031; the filing was accepted in April 2025 after about 8.72 million yuan of cumulative R&D. Hospital sales of the finished tablets were 891 million yuan in 2025 and about 293 million yuan in the first half of 2026, yet API consumption in 2025 was only about 0.46 tonnes, and nine registrants already held active status on the CDE platform as of 9 November. Separately, Tianjin Pharmaceutical's histidine API gained CDE status A in 25 kg drums, adding a twenty-sixth amino acid after a November 2024 filing, supplemental data from December 2025 to March 2026 and about 1.47 million yuan of R&D. Histidine carries an imidazole side chain, and IQVIA puts global sales of oral and injectable histidine preparations at 2.223 billion dollars in 2024 and 2.131 billion dollars in 2025, so an imidazole-family intermediate supports a sizeable formulation market. A third disclosure concerns a sarpogrelate hydrochloride intermediate made by a subsidiary of Heyi Pharmaceutical, which passed a Japanese PMDA GMP compliance inspection and received a conformity result notice, opening a direct supply route to Japanese formulation makers for the tertiary-amine-containing antithrombotic downstream product.

Product listings and promotional supplier pages were excluded.

3. Editor's Pick + Reason: The 0.46 tonne API volume behind 891 million yuan of finished-dose sales, alongside nine already-active registrants. Reason: It is the clearest available statement that high-value nitrogen chemistry competes on dossier quality, impurity control and multi-jurisdiction GMP clearance rather than on capacity. For intermediate suppliers, the practical signal is that a second regulatory jurisdiction, as with the Japanese inspection, is worth more than another reactor.

3. A 12 November DMF Note Exposes the Dimethylamine Chain, and a Herbicide Filing Shows Its By-Product Constraint

1. Summary: A commodity analysis published today by 100ppi describes the domestic DMF market as balanced but regionally soft, using data through 11 November. Its moving-average signal is a strong consolidation with a mild positive bias, not a directional trend: the 5-day average is flat, the 10- and 20-day averages narrow upward, and the 60-day, three-month and one-year prices sit in the low, middle and mid-high bands. Regional quotes on 11 November were 5,350 yuan per tonne ex-works at a Jiangxi producer with steady supply and demand, 5,400–5,500 yuan per tonne delivered in Shandong and North China with prices edging lower on just-in-time buying, 5,450–5,650 yuan per tonne in East China and 5,600–5,700 yuan per tonne in Guangdong, both centres reporting low gravity and slow shipments. For nitrogen producers the important line is the chain description: DMF's upstream inputs are aqueous dimethylamine, carbon monoxide, liquid ammonia and methanol, and its outlets include the insecticide chlordimeform, pesticide intermediates, pharmaceutical intermediates and solvent use. A dimethylamine balance therefore reads through to agrochemical and pharmaceutical intermediates even when the amide is quiet. On the capacity side, an October 2026 filing reported this month covers a 200 million yuan project in the Hebao section of Yongchang Industrial Park, Jinchang, Gansu: 4,000 tonnes per year of the triazolinone herbicide sulfentrazone, 11,500 tonnes per year of five captive intermediates and 42,000 tonnes per year of by-product sulfuric acid across three lines, with two agrochemical companies each holding 48 percent and the remaining 4 percent undisclosed. The acid stream is 2.7 times the main product volume and must be sold or consumed on site; no construction start or funding source was disclosed.

3. Editor's Pick + Reason: The 42,000 tonnes of by-product sulfuric acid attached to 11,500 tonnes of intermediates. Reason: Nitrogen-heterocycle projects are usually assessed on route and yield, but this filing makes acid logistics the binding constraint. A captive intermediate plan is only bankable if the sulphur balance clears, which is a more useful due-diligence question for amine suppliers than the headline nameplate capacity.

4. Biphasic Amine Solvents Cut Regeneration Energy, While Imidazolium Inhibitors Enter CO2 Corrosion Service

1. Summary: A study in Proceedings of the CSEE on low-concentration CO2 from combined-cycle gas turbines gives quantitative backing to phase-separating capture solvents using a biphasic blend of 3-dimethylaminopropylamine, N,N-dimethylcyclohexylamine and water. At 30 weight percent of the diamine with the tertiary amine to water ratio at 6:4, absorption at 313 K reaches 2.28 mol per kg and cyclic capacity after desorption at 383 K is 1.96 mol per kg. The loaded liquid splits spontaneously; the CO2-rich phase is 48 percent of the volume with 44.6 mPa.s viscosity. Carbon-13 NMR and quantum chemistry identify the carbamate as the main rich-phase product. Regeneration energy is 2.74 GJ per tonne of CO2, 38 percent below 30 percent monoethanolamine. A companion pilot on a 1 Nm3/h circulating rig reports 1.64 mol CO2 per kg cyclic load against 0.824 for MEA and 4.80 GJ per tonne regeneration heat against 6.71, at capture above 90 percent and purity above 99 percent; over 160 hours rich-phase components drifted by 2.50 to 6.36 percent. At the AIChE annual meeting in Minneapolis on 10 November, a diethylenetriamine biphasic solvent with catalytic regeneration using titania, Amberlyst-15 or homogeneous tertiary amines cut regenerated volume by up to 50 percent and energy per mole of CO2 by up to 48 percent versus MEA. A Chinese corrosion review published 11 November adds the oilfield side: the imidazolium ionic liquid 1-dodecyl-3-methylimidazolium hydrogen sulfate markedly improves inhibition on pre-corroded carbon steel, and water-based modified epoxy resin strengthens oil-well cement by filling pores and forming a polymer film. It also notes that protonated amines still drive hydrogen evolution, degradation and corrosion.

3. Editor's Pick + Reason: Regenerating only the 48 percent CO2-rich phase and reaching 2.74 GJ per tonne. Reason: Phase separation cuts reboiler volume, energy and equipment size at once. Paired with the 160-hour drift data and the imidazolium result, it shows specification moving toward long-run stability in capture and oilfield service.
