Surfactants, Catalysts

DMTDA is an environmentally friendly and low toxic liquid diamine chain extender, which is mainly used on polyurethane elastomer, rim (reaction injection molding), SPUA (sprayed polyurea elastomer) and adhesive; At the same time, it can also be used as epoxy resin curing agent. It has been widely used in polyurethane cots, medicine, stamping and so on. In addition, it is widely used in automobile, construction, coal mine, metal mine, textile, papermaking and printing industries.

Colorless or yellow crystals or liquids with deliquescent properties. Soluble in ethanol and ether, soluble in water. It is chemically active and can undergo addition or condensation reactions with ammonia, amides, aldehydes, and carboxyl-containing compounds. Glyoxal is mainly used in the textile industry. As a fiber treatment agent, it can increase the shrinkage and wrinkle resistance of cotton, nylon and other fibers. It is a durable pressing finishing agent. In Japan, this use accounts for 80% of the total consumption of glyoxal. Glyoxal is an insoluble binder such as gelatin, animal glue, cheese, polyvinyl alcohol and starch. Glyoxal is also used in the leather industry and for making waterproof matches. Glyoxal is a raw material for organic synthesis. 2D-resin is obtained by heating and condensing acetaldehyde, urea and formaldehyde in the presence of sodium carbonate, which is used as fabric finishing agent; glyoxal reacts with formaldehyde and ammonium sulfate to synthesize imidazole, and then synthesize imidazole antifungal drug clotrimazole, Miconazole, etc.; Glyoxal and o-phenylenediamine cyclization to obtain benzopyrazine: it is an intermediate of the anti-tuberculosis drug pyrazinamide. Hydroxyphenyl acetic acid produced from glyoxal has been industrially produced in Japan and used as an intermediate for antibiotics and vitamin A series products. Glyoxal is also used in the synthesis of berberine hydrochloride and the sulfa drug sulfamethoxazine. It is also used in insecticides, deodorants, corpse preservatives, and sand curing agents.

5-bromo-1-pentene is a compound that can be used in organic synthesis.

This product is often used to make surfactants, drugs and cosmetics. It is used as dispersant in pharmacy, cream and emulsifier in cosmetics. It is also used as rice field heat preservation agent, reservoir covering agent, defoamer, polishing agent, lubricant, etc. Octadecyl alcohol can be used in the production of leveling, resin and synthetic rubber, color film couplers, etc.

It is used as flux for silicate decomposition, dopant for semiconductor materials, fire-resistant additive for heat-resistant glassware and paint. It is the raw material for preparing elemental boron and various boron compounds. It is used in the production of alloy steel in metallurgical industry. It can also be used as catalyst for organic synthesis, additive of lubricant for high temperature and chemical reagent.
