Abstract
Hexamethyldiphenyl trisiloxane was synthesized by diphenyl silicon glycol and hexamethyldisiloxane.The optimum reaction conditions were determined: using strongly acidic cationic resin as catalyst,the amount of catalyst was 10% of the total mass,the reaction temperature was 70℃,the ratio of n(hexamethyldisiloxane)∶n(diphenyl silicon glycol) was 1.1,using methylcyclohexane as solvent,and the amount was 50% of the total mass of glycol and hexamethyldisiloxane,the reaction time was 120 min.
