Abstract
PURPOSE: To obtain the titled adduct useful as a calcium agent in the fields of medicines and food industry in high yield, by reacting an aqueous solution of sorbitol of high concentration with CaO or Ca(OH)2 at specific respective suitable temperatures, and drying and powdering the reaction solution.
CONSTITUTION: Calcium oxide powder is dissolved and reacted with an aqueous solution of sorbitol in a concentration of 50W85% while heating the solution at 70°C or above under stirring, or calcium hydroxide is added and reacted with an aqueous solution in a concentration of 60W100% or a melt thereof at 40W 140°C. The reaction solution is directly dried or concentrated and dried to give a powder and give the aimed sorbitol adduct of calcium. In case calcium oxide is used as the raw material, hot water is added to the reaction solution, and filtered while hot to remove the unreacted calcium oxide or formed calcium hydroxide. The resultant filtrate is then cooled, crystallized and separated to give the aimed substance.
