PROCESS FOR PRODUCING A T-BUTYL PHENOL FROM A C4 RAFFINATE STREAM

Document Type and Number:

WIPO Patent Application WO/2011/069052

Kind Code:

A3

Abstract:

This invention relates to processes for producing various t-butyl phenols, such as 2,6-di-tert-butyl phenol and ortho-tert-butyl phenol, by selectively reacting phenol or a substituted phenol with an isobutylene-containing C4 raffinate stream. The 2,6-di-tert-butyl phenol and ortho-tert-butyl phenol can be transalkylated to form other tert-butyl phenols, such as para-tert-butyl phenol, 2,4-di-tert-butyl phenol.
