METHOD OF PREPARING POTASSIUM PENTABORATE

摘要

FIELD: chemistry of boron compounds. SUBSTANCE: 0.05-0.1 weight parts of water is added to 1 weight part of the stoichiometric mixture of potassium carbonate and boric acid. The resulted mixture is agitated for 15- 30 min, then temperature is raised to 80-100 C and the product so obtained is completely dried under normal conditions. EFFECT: elevated yield of the product and simplified process.
