摘要： A method of preparing an organosiloxane comprises cohydrolyzing a mixture comprising a first silane compound having the general formula R2SiX2 and a second silane compound having the general formula R3SiR1 in the presence of an aqueous acid, wherein each R is independently selected from H and a hydrocarbyl group, each X is an independently selected halogen atom, and R1 is X or OSiR3. The organosiloxane is prepared in a reaction product. Optionally, the method comprises isolating the organosiloxane from the reaction product. The organosiloxane has the general formula R3SiO(R2SiO)nH, wherein n is an integer from 1 to 200.
