Title: Treatment of a feed mixture of hydrocarbon gases containing isobutylene
Inventor: HARLAN MCKEEVER CHARLES
IPC: B01J31/10
Filed: 1960-06-02
Abstract: Tertiary-butyl alkanoates are prepared by contacting a feed mixture of hydrocarbon gases containing isobutylene with an alkanoic acid (1-4C) at between -10 DEG C. and 50 DEG C., in the presence of a dehydrated sulphonic acid cation-exchange resin having a macioreticular structure. The t-butyl alkanoate may be separated from the unreacted gases and reconverted into isobutylene by refluxing with the cation-exchange resin and this process may be used for the separation of isobutylene from the hydrocarbon gases. The catalyst is obtained from a monomeric mixture of an unsaturated monomer containing CH2= C< groups in non-conjugated relationships and a mono-ethylenically unsaturated monomer e.g. a sulphonated cross-linked polymer of styrene and divinyl benzene. A mixture of alkanoic acid and anhydride may be used to react with any water present in the gaseous stream or in the resin after dehydration.  The process may be continuous or batchwise and the t-butyl alkanoate may be separated by fractionation. Examples describe the preparation of t-butyl acetate, and t-butyl butyrate. Specification 932,126 is referred to.ALSO:Isobutylene is separated from a mixture of hydrocarbon gases by contacting the mixture with an alkanoic acid (1-4 C), at a temperature - 10 DEG  C. to 50 DEG  C. in the presence of a dehydrated sulphonic acid cation-exchange resin having a macroreticular structure.  The t-butyl alkanoates formed may be separated and refluxed with strong acids e.g. sulphuric, or the low boiling unreacted hydrocarbons may be stripped and the reaction mixture refluxed in the presence of the dehydrated sulphonic acid cation exchange resin as above, to reform the isobutylene.  The catalyst is obtained from a monomeric mixture of an unsaturated monomer containing CH2 = C< groups in non-conjugated relationship and a mono-ethylenically unsaturated monomer e.g. a sulphonated cross-linked polymer of styrene and divinyl benzene. Examples describe the treatment of a refinery stream with acetic acid in the presence of a dehydrated macroraticular cross-linked copolymer of styrene and divinyl benzene, followed by fractionation to separate t-butyl acetate and acetic acid, which was then warmed to about 60 DEG  C. in the presence of a macroreticular sulphonated styrene-divinyl benzene copolymer and the isobutylene evolved collected.
