Zusammenfassung:FIELD: chemical technology. ^ SUBSTANCE: invention relates to a method for preparing calcium stearate used for stabilization of plastic masses, in manufacture of paint and varnish materials, vitamin and medicinal preparations. Preparing calcium stearate is carried out by interaction of stearic acid and calcium oxide or hydroxide in the equimole ratio of reagents. The process is carried out in the solid phase under atmosphere pressure and intensive stirring without heating in the presence of zeolite of CaX type taken in the amount 6.7-16 wt.-%. Method provides simplifying technology due to a single stage process and improvement of economical indices. ^ EFFECT: improved preparing method. ^ 7 tbl, 3 ex
