Paragraph 0013, (2016/12/01)
The invention belongs to the technical field of fine chemistry and relates to a methyltris(methylethylketoxime)silane preparation method.Methyltrimethoxysilane, diacetylmonoxime and p-toluenesulfonic acid which serves as a catalyst react according to a certain proportion, excessive diacetylmonoxime in the reaction process serves as a solvent to make the reaction more thorough and easier, and methanol is recovered during reaction. After reaction is finished, the diacetylmonoxime which serves as the solvent is recovered by reduced pressure distillation, and the recovered diacetylmonoxime can be recycled.Products obtained by distillation are washed and filtered to obtain high-purity methyltris(methylethylketoxime)silane. The methyltris(methylethylketoxime)silane preparation method has the advantages that product yield is above 97%, product content is above 98%, materials can be recycled completely, no waste liquid is generated, and accordingly environment pollution is avoided.

The stereoisomers of 2-butanone O-trimethylsilyloxime were observed as separate peaks, the intensity ratio being 1:3, by high resolution GC equipped with a capillary column. The peak with intensity 3 was assigned to the Z isomer of oxime bond and the intensity ratio corresponded to the stereoisomer ratio of 2-butanone oxime. Silanes including plural oxime groups also gave separate stereoisomer peaks corresponding to the isomer ratio of 2-butanone oxime.
