FIELD: chemistry.
SUBSTANCE: invention relates to a method for producing lithium hydroxide. The method involves the reaction of lithium carbonate and calcium hydroxide in water to produce an aqueous solution of lithium hydroxide, while the concentration of lithium carbonate in water is in the range from 25 to 110 g/l.
EFFECT: method makes it possible to obtain lithium hydroxide from lithium carbonate using a small amount of energy and a high degree of lithium extraction.
