Abstract:
1. A method of preparing and purifying a product through a reaction distillation process comprising the steps of: contacting a first amount of a metalloid or metal selected from a group consisting of Zinc and an element located in periodic table group 13-16 with a first amount of a polyol in a reaction-distillation zone in, a single, reaction apparatus and, resulting from said contacting, forming a metal alkoxide composition having the element located in periodic table group 13-16 contained therein, the metal alkoxide compound formed from a reaction of said element located in periodic table group 13-16 compound and said polyol; simultaneously with said contacting, continuously removing reaction products from a vapor phase of said reaction-distillation zone; and simultaneously with said contacting of said first amount of the metalloid or metal selected from a group consisting of Zinc and an element located in periodic table group 13-16 with first amount of the polyol in the reaction-distillation zone, continuously removing reaction products from a liquid phase of said reaction-distillation zone; and modifying the metal alkoxide's flame retardant properties by adding a flame retardant additive to the metal alkoxide selected from a group consisting of a metal oxide ceramic, a thermoplastic, and a thermoset polymer.
