摘要

1,3-bis - (1-methyl-1-isocyanate-ethyl) carbamate, structure 1 containing 12-40% ethylene dioxide (- ch2-ch2-o -) by weight,It refers to the weight of carbonate the preparation method of these carbonates and the mixture containing carbonate and the compound containing ester structure. Carbonate can be obtained by the conversion of 1,3-bis (1-methyl-1-isocyanate-ethyl) benzene and the presence of carbon dioxide separation catalyst,In anthrax, the carbon structure containing ethylene oxide (- ch2-ch2-o -) in polyphosphate (I) containing at least one reactive compound is then reacted. The reaction of isocyanate and reaction group to isocyanate is generally 10:1 to 0.2:1, preferably 5:1 to 0.5:1, preferably 1:1 to 0.5:1, especially 1:1. Alternatively, they may be obtained by reacting p-1,3-di - (1-methyl-1-isocyanate-ethyl) benzene with at least one compound (I) containing an ethylene oxidation device (- ch2-ch2-o -).Due to the relationship between the used social particles and the reaction group's isocyanate, at least 2:1 and below are converted into reaction products. The isocyanate group is introduced in front of the carbon oxidation catalyst. Procedures for preparation of polyurethane, conversion of polyurethane, reaction compounds with isocyanates, extenders and possible catalysts, auxiliary substances and / or additional substances,The transformation of endonde was witnessed by anthrax. Organic carbonates are well known and are used as stabilizers to avoid hydrolytic degradation of compounds containing groups such as esters. Polymeric and porous products such as polyurethane and water vision devices.
