Process introduction:

Our process for the preparation of tert.-amyl alcohol (TAA) comprising conducting a hydration reaction of a reaction mixture consisting of an (a) i-amylene or a C5 -distillation cut containing i-amylene, relative to the amount of iso-amylene, on an acid cation exchanger, wherein the reaction is carried out in a range from 5C. below to 5C. above the boiling point of the i-amylene or the C5 -distillation cut.

The process is particularly characterized in that it is carried out in the vicinity of the boiling point of the i-amylanes. For this purpose, the reaction is carried out, in particular, in a range from 5 below to 5 above the boiling point of the i-amylenes at the reaction pressures set in each case. Preferably, it is carried out in a range from 5 below to 2 above the boiling point of the i-amylenes, particularly preferably in a range from 2 below to 2 above the boiling point.

The i-amylenes to be hydrated (2-methyl-1-butene and 2-methyl-2-butene) can be used in the form of the C 5 distillation cut (so-called benzene forerun) or particularly preferably in the form of concentrated or even essentially pure i-amylenes.

The process allows higher TAA contents in the reaction mixture than processes of the prior art. These higher contents are 25-60% by weight, typically 40-50% by weight, relative to the sum of TAA and i-amylenes (if used as pure i-amylenes, relative to the entire reaction product).

Engaged in deep processing of C4/C5 for many years, right now our tert-amyl alcohol  annual output is over 2,000 tons. with advantages of raw material and technology, enable our product always to keep competitive in the international market.
