Abstract
Cyclohexylmethyldichlorosilane(CMCS) was synthesized from dichloromethylsilane(DCMS) and cyclohexene via hydrosilylation with silica supported Pt catalyst.Its structure of CMCS was characterized by means of FT-IR and GC-MS.Effects of the molar ratio of raw materials,catalyst dosage,used property,reaction temperature and reaction time on the yield of CMCS were inverstigated.Optimal reaction conditions for preparation of CMCS were cyclohexene 0.1 mol,n(cyclohexene)∶n(DCMS)=1.0∶1.1(mol/mol),catalyst 1.0 g,reaction pressure 1.0 MPa,reaction temperacture 80~90 ℃,reaction time 5 h.Under above optimal conditions,the yield and mass fraction of CMCS could be up to 92.0% and 99.2% respectively.
