TDI
The primary as a polyurethane resin is produced for producing polychlorofoxy plastics, coatings, rubber, binders, sealants, and the like. It can also be used as a rubber vulcanizing agent, a protein crosslinking agent, and the like. Contains foam; polyurethane coatings; polyurethane rubber; polyimide fibers and adhesives, etc. also use.
The toluene diisocyanate has 2,4-toluene diisocyanates and 2,6-toluene diisocyanate (TDI). According to the two isomers, there are three standard products: (1) TDI-65 contains 2,4-TDI65%, 2,6-TDi35%; (2) TDI-80 contains 2, 4-4- TDI80%, 2,6-TDI20%, most common; (3) TDI-100 contains 2, 4-TDI100%. Carbon dioxide occurs with water effects. Easy to contain a compound of the active hydrogen atom. Wireful polyurethane or polyurethane resin with the diol effect.
Mixed with diethyl ether, diethylene glycol, acetone, tetrachloride, benzene, chlorobenzene, but oil, olive oil. Aminomethalate, urea, urea, or the like can be formed in antifungal compound, water, amine, and compound having an active hydrogen atom. Toluene is nitrified to nitrate 2, 4- and 2,6-dinitr-nitrosyltellate, and then hydrotreated with the nickel catalyst to give 2, 4- and 2,6-di ammonial, and then in the chlorobenzene solution and light Gas response.
