nol Alkylation Technology
Proprietary Technology and Plants
Technology Introduction:
Alkyl nol is produced by the alkylation of nol by reacting with olefin, alitic 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 nolâs alkylation into o-cresol, and cresolâs alkylation into 2-t-butyl-p-cresol, 6-t-butyl-m-cresol, 2,6-di-t-butyl-p-cresol, 2,3,6-trimethylnol (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:
He+reinafter 2,3,6-TMP production technology will be introduced as an example. 2,3,6-TMP is mainly used in rmaceutical 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 nol and methanol, SL Tec offers the one-step process starting from m-cresol and methanol under gas se catalysis. The catalyst is based on Fe2O3, with the conversion of m-cresol reaching 98% and the yield reaching 98%.
Performance:
