Basic aluminum bromide-polyol complexes and methods of making same
Abstract
Abstract COMPLEXES OF BASIS ALUMINA BROMIDES CONTAINING POLYHYDROXY VOMPOUNDS (POLYOLS) ARE PREPARED BY HEATING AN AQUEOUS SOLUTION OF BASIC ALUMINUM BROMIDE UNDER REFLUX CONDITIONS, MIXING THE SOLUTION WITH POLYHYDROXY COMPOUND HAVING AT LEAST TWO CARBON ATOMS WHICH ARE LINKED TO HYDROXY GROUPS, AND DRYING THE RESULTING MIXTURE TO A SUBSTANTIALLY FRIABLE SOLID, PREFERABLY BY SPRAY DRYING. THE RESULTING COMPLEXES PREFERABLY CONTAIN ABOUT 5 TO 20 WEIGHT PERCENT OF POLYOL AND LESS THAN ABOUT 17 WEIGHT PERCENT WATER. SUCH COMPLEXES HAVE A HIGH DEGREE OF SOLUBILITY IN ANHYDROUS ALCOHOL AND AN UNEXPECTEDLY HIGH COMPATIBILITY WITH HALOGENATED HYDROCARBONS. THESE PROPERTIES MAKE THE COMPLEXES SUITABLE FOR AEROSOL FORMULATIONS AND PARTICULARLY ANTIPERSPIRANT COMPOSITIONS.
