Synthesis method and application of 1, 3-bis (isocyanate alkyl)-1, 1, 3, 3-tetramethyldisiloxane

The invention discloses a synthesis method and application of 1, 3-bis (isocyanate alkyl)-1, 1, 3, 3-tetramethyldisiloxane, which relates to the technical field of compound synthesis. According to the synthesis method, cyanate, alkyl alcohol and chloralkane silane react to obtain carbamic acid alkyl ester silane, so that the raw material input cost is effectively reduced; trimethylchlorosilane is used as a protective agent to protect secondary amine on the alkyl carbamate double end socket, so that polymerization reaction phenomena such as by-products and the like are prevented from occurring again in the cracking process. The synthesis method is simple in process, short in synthesis time and high in synthesis efficiency, the yield of a finished product can reach 95% or above, and industrial mass production is facilitated. The 1, 3-bis (isocyanate alkyl)-1, 1, 3, 3-tetramethyldisiloxane is mostly applied as a preparation raw material in polyurethane, coatings, sealants and polyether modified products.
