Abstract
1,054,534. Sulpholanes and their manufacture and purification. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. June 21. 1965. No. 26046/65. Heading C2C. A sulpholane is purified by subjecting it to an extractive treatment with an aliphatic hydrocarbon or mixture of aliphatic hydrocarbons, the term " aliphatic hydrocarbons " being used to include cycloaliphatic hydrocarbons. The hydrocarbons are preferably those which are at least partially immiscible with the sulpholane and which can be separated from the latter by distillation and one or more other compounds may also be present but the presence of aromatic hydrocarbons should be avoided. Specified solvents are cyclohexane and petroleum ether (B.P. 60-80‹ C.). The process is preferably carried out within the temperature range 20- 60‹ C. and in at least two stages. The purified sulpholane may be used as a solvent for the manufacture of a sulpholane, by reacting a 1: 3 alkadiene with sulphur dioxide to produce a sulpholene and catalytically hydrogenating the sulpholene. both steps of the process being carried out in the presence of the purified sulpholane. The hydrogenation may be carried out, in the case of 3-sulpholene, in the presence of Raney nickel and at 30‹ C. under a hydrogen pressure of 500 p.s.i.g. in a stirred autoclave.
