Preparation process of boric acid-glycerol preparation

The invention relates to a preparation process of a boric acid-glycerol preparation from boric acid and glycerol, comprising the following steps: (1) placing glycerol 40-50 parts in a weight-stabilized evaporating dish; (2) heating to 140-150 DEG C in a sand bath; (3) adding boric acid 30-40 parts in total in 2-4 times while stirring; (4) dissolving, heating at the same temperature while stirring at intervals to break the film formed on the liquid surface; (5) when the total weight of reactants is reduced to 50-60 parts, slowly adding glycerol 40-50 parts while stirring; and (6) when the total weight of reactants is 100 parts, pouring into a proper drying bottle, and sealing to obtain the boric acid-glycerol preparation. According to the preparation process of the invention, the product quality is ensured, and the success ratio of experimental preparation is increased.
