Procedure
This cyclohexyldichlorosilane in an amount of 139.3 g (0.761 mol), 95.1 g of 1-hexene (1.16 mol) and 0.05 mol % of chloroplatinic acid (relative to cyclohexyldichlorosilane) were reacted by heating in an oil bath at 60° C. for 3 hours with stirring. Thereafter 183.5 g (0.69 mol) of hexylcyclohexyldichlorosilane was obtained by vacuum distillation. The yield relative to cyclohexyldichlorosilane was 90.7% and that relative to dichlorosilane was 83.2%. This hexylcyclohexyldichlorosilane had a boiling point of 92°~95° C./1.5 mmHg and a refractive index nD20 of 1.4744. The results of elemental analysis were as follows: measured value, C, 54.28%; H, 9.15%; Cl, 25.6%, theoretical value, C, 53.92%; H2, 9.05%; Cl, 26.83%. Further infrared spectrum is shown in FIG. 3 and NMR spectrum is shown in FIG. 7 and from the above-mentioned result, it was confirmed that the product had a formula (cyclohexyl)(n--C6H13)SiCl2.
