HIGH-PURITY MONOALKENYL-CONTAINING GLYCERIN DERIVATIVE, AND METHOD FOR PRODUCING SAME

摘要

The present invention relates to a monoalkenyl-containing glycerin derivative having purity of 92% or more and an electrical conductivity of 50 µS/cm or less. The monoalkenyl-containing glycerin derivative can be produced by a production method comprising: step (A) of reacting a ketalized glycerin derivative with a monoalkenyl glycidyl ether in the presence of an inorganic base to produce a ketal of a ketalized glycerin derivative; step (B) of purifying the ketal produced in step (A) by distillation; and step (C) of hydrolyzing the ketal produced in step (B). According to the present invention, it becomes possible to provide a high-purity monoalkenyl-containing glycerin derivative which can be produced hardly so far. Furthermore, it also becomes possible to provide a glycerin-derivative-modified silicone that is chemically stable and has excellent practical usefulness including emulsifiability and excellent blend stability and a use of the glycerin-derivative-modified silicone using the monoalkenyl-containing glycerin derivative
