PROCESS FOR PREPARING POTASSIUM PENTABORATE

摘要

FIELD: inorganic chemistry. SUBSTANCE: potassium carbonate, boric acid in stoichiometric ratio, water is added in weight ratio of water to solid boric acid and solid potassium carbonate of (0.05-0.1):1, the mixture is stirred for 15-30 minutes, temperature is raised to 80- 100 C and the resulting synthesis product is kept till it becomes completely dry. Invention makes it possible to increase the yield of product to 90-95% and simplify claimed process. EFFECT: more efficient preparation process. 3 ex
