Abstract
The invention relates to a process for preparing tert-butanol by reaction of a homogeneous mixture comprising water, tert-butanol and an isobutene-containing hydrocarbon mixture over an acidic ion-exchange resin at from 30 to 120° C., wherein the homogeneous mixture contains, at a proportion by mass of isobutene of above 10%, from 30 to 80% of the maximum amount of water made possible by the solubility of water in the mixture of tert-butanol and the isobutene-containing hydrocarbon mixture.
Claims20
A process for preparing tert-butanol comprising contacting a homogeneous reaction mixture comprising water, tert-butanol and an isobutene-containing hydrocarbon mixture with an acidic ion-exchange resin at from 30 to 120° C., wherein the homogeneous reaction mixture prior to said contacting has a proportion of isobutene of over 10% by mass and a proportion of water which is from 30 to 80% of the amount of water which is possible based on the solubility of water in the homogenous reaction mixture.
