Abstract: The present invention pertains to a process for making an alkyl ester of a carboxylic acid via transesterification comprising the steps of: (1) reacting a carboxylic acid ester with an alcohol and an effective amount of a transesterification catalyst in a reaction zone to form a reaction mixture comprised of a product ester and a product alcohol; (2) passing the reaction mixture from step (1) through a centrifugal separation zone wherein the second alcohol is separated from the second ester. The process according to the invention allows for shorter reaction times and improved product yields.

Abstract: Defoamers are the products of the reaction of epichlorohydrin and compounds having the formula II
R3(EO)n(PO)mOH (II)
wherein R3 is an alkyl, alkenyl or arenyl group having from 4 to 22 carbon atoms; a substituted alkyl or alkenyl group having from 4 to 22 carbon atoms wherein; n is a number from 0 to 50 and m is a number from 0 to 10; wherein the mole ratio of epichlorohydrin to (II) is from about 0.60/1 to about 2/1 are extremely efficient defoamers for aqueous surfactant systems. The defoamers are added to a surfactant in an amount sufficient to reduce or eliminate foam and have the advantage of being totally dispersible in water, are readily biodegradable, contain no organic solvents and do not affect the detergency of surfactants with which they are used because they are nonionic surfactants in themselves.
