Abstract
969,994. Separating hydrocarbons. OFFICE NATIONAL INDUSTRIEL DE L'AZOTE. Sept. 26, 1962 [Oct. 5, 1961], No. 36588/62. Drawings to Specification. Heading C5E. Aromatic hydrocarbons are separated from petroleum reformates also containing aliphatic and naphthenic hydrocarbons by solvent extraction using as solvent a mixture containing 5-15% vol. of water and one or more C 1 -C 6 alkyl esters or thio-esters of carbamic acid or thiocarbamic acid or an N-C 2 -C 4 -alkyl derivative thereof.
