Abstract
PURPOSE: To prepare easily handleable granular dehydroacetic acid useful as an industrial fungicide, pesticide, food additive, etc., by dispersing molten dehydroacetic acid in an aqueous solution of a monoglyceride or a sorbitan mono-fatty acid ester.
CONSTITUTION: Granular dehydroacetic acid is prepared by dispersing molten dehydroacetic acid in a 1W500ppm aqueous solution of a monoglyceride wherein the C-number of the fatty acid group is 12W22 or a sorbitan mono-fatty acid ester (e.g. stearic acid monoglyceride). More concretely, dehydroacetic acid is molten by heating at 115W140°C, introduced into water through a nozzle having a diameter of 1W2.5mm, and throughly agitated to obtain granular product. The ratio of dehydroacetic acid to water is pref. 1W10%. The cooling of the molten dehydroacetic acid is carried out at 40W80°C.
EFFECT: Scattering of fine powder and the blocking phenomena during packaging and transportation can be prevented.
