Chinese name : 1,6 - 1,6; 1,6-diamino - hexane; Others Ylmethyl diamine; Hexamethylenetetramine diamine; F diamine; 6-methyl-diamine; others hold diamine

English name : 1,6-Hexanediamine; 1,6-Diaminohexane; Hexamethylene diamine; 1,6-Hexamethylenediamine; 1,6-diamino-n-hexane; 1,6 - hexylenediamine; hexamethylenediamine; 1,6-diamino - hexan; hmda; 1,6-hexane diamine; hexamethylenediamine (1,6-hexanediamine); hexamethylenediamine, solid; hexamethylenediamine, solution

nature Description : flake white crystals, ammonia smell Flammable. 41-42 ° C melting point, boiling point, 204-205 ° C and 100 ° C (2.67 kPa), 46-49-47 ° C (0.133 - 0.267kPa), the relative density of 0.883, viscosity (50 ° C) 1.46mPa ; s, 1.4498 refractive index, a flash point of 81 ° C. Water-soluble : 0 ° C, 100 ml water soluble 2.0g, 30 ° C, 100 ml water soluble 0.85g; Insoluble ethanol; Ethyl ether and benzene. From the air to absorb carbon dioxide and water. With pyridine odors.

production methods : diamine furfural production initially used as raw materials, production Hexanediamine more industrial methods, according to the different materials used are adipic acid; Butadiene; Acrylonitrile; Hexandiol law and the law of caprolactam. Which adipic acid; Law and acrylonitrile butadiene polymerization of two intermediate others after two nitrile H2 Hexanediamine, at present almost all large-scale production Hexanediamine solution to the two others via Catalytic Hydrogenation.
1. Industry has two catalytic hydrogenation of a nitrile high pressure and low pressure two.
(1) high-pressure method used cobalt-copper catalyst, the reaction temperature is 100-135 ° C, pressure 60-65MPa; Also available iron catalyst, the reaction temperature is 100-180 ° C, pressure on available ammonia, sometimes joined Aromatics (such as toluene). Hexanediamine selective about 90-95%. Production of liquid has nitrile; Toluene and ammonia and hydrogen and a small amount of ammonia has two nitriles and toluene mixture of gases containing cobalt-into-copper catalyst reactor, the formation of rough Hexanediamine derived after it first with the water azeotropic distillation, and then through several vacuum distillation that is to be suitable for manufacturing nylon 66 the high-purity products.
(2) low pressure using Raney nickel; Iron-nickel or chromium-nickel catalyst, the reaction of the sodium hydroxide solution for. Reaction temperature is about 75 ° C, pressure 3MPa, 1,6-selective up 99%. In order to prevent catalyst poisoning, the right raw materials has two nitrile high purity requirements. 1. Adipic acid as raw materials to the method of this law is to adipic acid vapor and excessive ammonia together by heating to 340 ° C, such as dehydration silica catalyst, generating two others nitrile, and then joined them in methanol and ammonia using nickel as the catalyst diatomite, 90-100 ° C to 10 .1325-20.265 MPa hydrogen for reduction in finished. 3. Caprolactam laws generally used to dealing with such small lactamase production unit. It is in caprolactam with ammonia phosphate (such as manganese; Aluminum; Calcium; Barium or zinc phosphate), the presence of catalysts, gas produced by the reaction amino acetonitrile, the reaction temperature of 350 ° C, the yield was almost 100%. Generation of aminocaproic nitrile further hydrogenation generation Hexanediamine, and the process has two similar nitrile hydrogenation.

purposes : most of the goods for synthetic nylon 66 and 610 resin, polyurethane resin used for synthesis; Ion exchange resins and sub-hexyl diisocyanate, and for urea - formaldehyde resin; The epoxy curing agents, crosslinking agents, such as organic, but also for the textile and paper workers industry stabilizer; bleach, alloy corroding agent and the inhibition emulsifiers such as neoprene. Has diamine and hydrochloric acid at 28 ° C to be 1,6% salt - has dihydrochloride ([6055-52-3]), can be used to produce microbicides chlorhexidine acetate. The 1,2-bonding agent; Aviation paint and Vulcanizing agents have production applications.
