Phenol Alkylation Plant

Process Flow Diagram for Phenol Alkylation Plant

Technology Introduction for Phenol Alkylation Plant

Alkyl phenol is produced by the alkylation of phenol by reacting with olefin, aliphatic alcohol, or chloro-hydrocarbon. They are important intermediates for fine chemical synthesis, widely applied in the manufacture of surface active agent, anti-oxidation agent, paint and coating. SL TEC offers the technology of phenol's alkylation into o-cresol, and cresol's alkylation into 2-t-butyl-p-cresol, 6-t-butyl-m-cresol, 2,6-di-t-butyl-p-cresol, 2,3,6-trimethylphenol (2,3,6-TMP) and etc.

Also SL TEC supplies the technology of producing m-cresol/p-cresol by the isomerization of o-cresol.

Technical Features for Phenol Alkylation Plant

Hereinafter 2,3,6-TMP production technology will be introduced as an example. 2,3,6-TMP is mainly used in pharmaceutical industry to synthesize vitamin E; it is the monomer for the production of thermoresitant PPE engineering plastic and the feedstock for plastic alloy production; also 2,3,6-TMP is the necessary intermediates for the manufacture of some pesticides, disinfectants and etc.

Compared to the process starting from phenol and methanol, SL Tec offers the one-step process starting from m-cresol and methanol under gas phase catalysis. The catalyst is based on Fe2O3, with the conversion of m-cresol reaching 98% and the yield reaching 98%.
