| titleOfInvention | A kind of preparation method of unsaturated organosilazane |
| abstract | The invention provides a preparation method of unsaturated organosilazane, which comprises the following steps: mixing organosilicon compound, organic solvent and metal halide, adding acylating reagent dropwise at 50-100 DEG C and stirring condition, and refluxing for 3-8h , to obtain R 1 R 2 R 3 SiX; the X is selected from Cl, Br or I; the organosilicon compound is selected from R 1 R 2 R 3 SiOR 4 or R 1 R 2 R 3 SiOSiR 1 R 2 R 3 ; The R 1 is selected from an alkyl group containing a double bond functional group; the R 2 and R 3 are selected from an alkyl group containing a double bond functional group, a C1-C4 hydrocarbon group or a phenyl group; the R 4 is selected from a C1-C4 group Hydrocarbon group; the R 1 R 2 R 3 SiX is passed into ammonia gas for reaction to obtain unsaturated organosilazane R 1 R 2 R 3 SiNHSiR 1 R 2 R 3 . The method is simple, with mild conditions, no pollution and high yield. The yield of R 1 R 2 R 3 SiNHSiR 1 R 2 R 3 is 95-96%. |
