Stearate some simple methods

One kinds of stearyl alcohol ester synthesis method in the case of organic synthesis technology esters , stearic acid and stearyl alcohol as raw materials , characterized in that the metal oxide catalyst PVC processing aid  under nitrogen esterification atmosphere , alcohol , filtration obtained stearyl stearate ; said metal oxide is magnesium oxide or stannous oxide or iron oxide , etc., added in an amount of stearic acid and stearyl alcohol, total 0.03 to 0.12% by weight . Rational use of the present invention the metal oxide as a catalyst , such catalysts have high selectivity , non-corrosive equipment, production process is simple, can be removed by filtration , the inganic pigments  product quality is stable ; while the metal oxide catalyst according to requirements, optimized design and trial research , reasonably determine the ratio of raw materials , amount of catalyst , reaction temperature, time and other parameters and conditions , mild reaction conditions , using simple equipment, so that equipment investment is more savings.
