摘要： A process for separating an emulsion into separate and easily recoverable phases is disclosed. The process comprises exposing said emulsion, comprising a discontinuous phase and a non-conducting continuous phase, to an electric field thereby effecting coalescence of said discontinuous phase into droplets of a size for effective gravitation from the continuous phase, where the discontinuous phase and the continuous phase have different dielectric constants and densities and at least one of the phases comprise a silicon containing compound or a silicon containing polymer. This process is especially useful for separating emulsions where the discontinuous phase is an aqueous acid solution and the continuous phase is diorganopolysiloxane.

摘要： This invention relates to a method of forming activated antiperspirant salts, wherein the activated salts are formed by heating a solution of Z 2 (OH) 6-a X a , wherein Z is a member selected from the group consisting of aluminum, zirconium and mixtures thereof, a ranges from 0.3 to 4 and X is a member selected from the group consisting of Cl, Br, I and mixtures thereof, to a temperature from about 140° to about 200 °C. for a period of time ranging from one to five minutes or one to thirty minutes if a recycling loop heat exchanger is used and then drying said salt solution in its activated state. This process provides a much more rapid means of making activated antiperspirant salts, as it is taught in the art to heat the starting materials for periods up to thirty days.
