Phenol Alkylation Plant

Phenol Alkylation Plant
Product Description
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.
Phenol Alkylation Plant feature
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%.
