Patent GB-596463-A (GB)
Title: Improvements in the removal of conjugated diolefines from mixtures containing them
IPC: C07C7/17
Filed: 1945-07-11
Abstract: Conjugated diolefines are removed from hydrocarbon mixtures containing them by first reducing the diolefine content of the mixture by heating it with sulphur dioxide, whereby part of the diolefine is caused to react with the sulphur dioxide to form the corresponding diolefine sulphone, separating the sulphone so formed, and then heating the remaining mixture with an ester of maleic acid or of a substituted maleic acid, e.g. citraconic, pyrocinchonic or diphenylmaleic acid.  The diolefine content is preferably reduced to 5 to 8 per cent by reaction with the sulphur dioxide.  Temperatures of 80 DEG  to 150 DEG  C. may be used under a pressure sufficient to keep the diolefine in the liquid phase. Suitable maleic esters specified are dibutyl-, dimethyl-, diethyl-, dipropyl-, diisopropyl-, di-hexyl-, di-octyl-, di-lauryl-, di-hexyl-, di-octyl-, di-lauryl-, di-cyclohexyl-, di - (2 - ethyl - hexyl)-, di - (2 - methoxy - ethyl) maleates, and also mixed esters.  An excess of 2.5 to 6 molecular equivalents of the maleic ester is preferably used.  The following diolefines are specified: butadiene, isoprene, 2,3-dimethyl butadiene, and cyclic diolefines such as cyclopentadiene and 1,3-cyclohexadiene. In an example, dibutyl maleate is placed in a pressure vessel and there is introduced a hydrocarbon mixture containing 5-4 per cent of butadiene, which has been obtained by fractionating the cracking products of a Pennsylvanian gas oil and removing from the C4 fraction the greater part of its butadiene by reaction with sulphur dioxide.  After heating to 130 DEG  C., the dibutyl tetrahydrophthalate formed is recovered from the product by fractional distillation.  The tetrahydrophthalic acid esters are useful as plasticizers and high-boiling solvents for cellulose acetate, polyvinyl chloride and polyvinyl acetate.
