4-枯基酚与2,4-二枯基酚联产工艺
Process for co-production of 4-cumylphenol and 2,4-dicumylphenol
摘要
Abstract
A co-production process for 4-cumylphenol and 2,4-dicumylphenol was developed. The effect of raw material ratios, amount of catalysts, reaction temperature and dosage of re-crystallization solvents on alkylation of phenol and α-methyl-styrene were studied. Approximate 100% phenol conversion, and above 90% yield of 4-cumylphenol and 2,4-dicumylphenol were obtained. The purity of 2,4-dicumylphenol was better than 99% when a two-step re-crystallization with different solvents was employed. The emission of wastewater phenol-containing and other organic pollutants can be completely avoided when a new in-situ neutralization method was utilized for removal of catalysts. The problems of the present production technologies of 4-cumylphenol and 2,4-dicumylphenol, including difficulties in separation and purification, low yields and environmental pollution, could be solved.关键词
