FIELD: manufacturing technology.
SUBSTANCE: invention relates to a method of producing granules. Described is a method of producing granules of at least one salt of an alkali metal aminopolycarboxylic acid (A), including steps of (a) providing an aqueous suspension of an alkali metal salt of aminopolycarboxylic acid (A) selected from alkali metal salts of methylglycine diacetic acid, (b) maintaining said aqueous suspension at a temperature in range of 50 to 90 °C for a period of time in range of 3 to 10 hours, gas from 150 °C to 350 °C.
EFFECT: technical result is the creation of granules with excellent properties, high resistance to percarbonates and low hygroscopicity.
