FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing granulated zinc stearate, which is used as a plasticizer and activator for vulcanisation of rubber, a heat stabilizer and internal lubricant in making articles from PVC. Proposed method includes following stages: a) obtaining molten zinc stearate by mixing stearic acid and zinc oxide, followed by mixing at rate of 100-500 rpm at temperature of 180-200 °C for 1-5 hours; b) obtaining a zinc stearate suspension by dispersing a zinc stearate melt with isopropyl alcohol, followed by filtering the suspension; c) zinc stearate granulation with subsequent drying.
EFFECT: high output of zinc stearate.
