Title: Improvements in or relating to the production of oil soluble alkyl aromatic sulphonates
IPC: C07C309/62
Filed: 1954-04-02
Abstract: Oil-soluble alkyl aromatic sulphonates are prepared from an aromatic extract of petroleum obtained by extraction with liquid sulphur dioxide, furfural or other like selective solvent, of a petroleum distillate fraction boiling in excess of 300 DEG  C., the mean number of carbon atoms in the ring portion of the aromatic hydrocarbon extract thereby obtained being greater than 6, by alkylating the extract with an olefine boiling in excess of 150 DEG  C. or a hydrocarbon mixture containing said olefine and having an olefine content of not less than 50 per cent, the petroleum distillate fraction and olefine being so selected that the ratio of the mean number of carbon atoms in the existing side-chain of the aromatic extract plus the mean number of carbon atoms in the alkylating olefine to the mean number of carbon atoms in the ring portion of the aromatic extract falls within the range of 1 to 2.5 and thereafter sulphonating the resulting alkylate with sulphuric acid or oleum and neutralizing the product with an alkali.  The said ratio should be about 1.6 when the mean number of ring carbon atoms is 10.  The preferred process comprises purifying the aromatic extract by a sulphuric-acid treatment, then alkylating the extract using a weight ratio of aromatics to olefins of 1 : 1 to 20 : 1 at a temperature not exceeding 0 DEG  C. with sulphuric acid as catalyst; the alkylation product is neutralized and distilled to recover alkylate free from unused reactants and sulphonated in a refrigerant solvent, e.g. liquid SO2 or butane and the product neutralized after removal of the solvent.  To obtain a neutralized product free from unreacted alkylate neutralization may be effected with caustic soda in aqueous alcohol, followed by extraction of unreacted alkylate by petroleum ether.  An example employs a sulphur dioxide extract of a lubricating oil distillate boiling in the range 300-400 DEG  C. and a hydrocarbon fraction B.P. 240-320 DEG  C. containing C14-18 olefines.  The neutralized product, after removal of volatiles, is freed of oil by two-solvent counter-current extraction using 50 per cent aqueous isopropanol and petroleum ether as the solvents.  Specification 641,439 is referred to.
