METHOD FOR PRODUCTION OF 2,6-DI-TERT-BUTYL PHENOL STABILIZING AGENT Russian patent published in 1996 - IPC

Abstract RU 2054414 C1

FIELD: organic chemistry. SUBSTANCE: desired product has essential formula C₇₃H₁₀₈O₁₂, its melting point being 114-115 C. β-(3,5-di-tert-butyl-4-oxyphenyl)-propionic acid is used as reagent 1, mixture of polyoxypropylene glycol ethers of n-butyl alcohol having molecular weight 4300-4400 is used as reagent 2. After crystallization thus obtained product is treated by 20-30 mass parts of b-(3,5-di-tert-butyl-4-oxyphenyl)-propionic acid and 0.2-0.3 mass parts of mixture of polyoxypropylene glycol ethers of n-butyl alcohol. EFFECT: improves efficiency of method. 1 tbl
