METHOD FOR PRODUCTION OF PENTAERYTRITOL Russian patent published in 1996 - IPC

Abstract RU 2053215 C1

FIELD: organic chemistry. SUBSTANCE: pentaerytritol is dried at 45-55 C till moisture content and volatile content is 1.0-1.5 %. Then it is ground to particles having size 1-2 mm and is treated by heat. The latter process is carried out within 3-5 s with the help of heat carrier being preliminary heated to 160-180 C and having rate 20-30 m/s. Mass portion of moisture and volatile in desired product is 0.07-0.08. EFFECT: improves efficiency of method. 1 tbl
