Abstract
A process for producing lower alcohols is presented in which an olefinic feed and H.sub.2 SO.sub.4 react to form a mixture comprising alkyl sulfates, alkyl disulfates, fat acid, and nonpolar hydrocarbons. The mixture is separated into two phases, a nonpolar phase comprising nonpolar hydrocarbons and a polar phase comprising alkyl sulfates, alkyl disulfates, and fat acids. A rag-layer that forms between the nonpolar and polar phases comprising carbonaceous particulate material is removed by contact with an extraction reagent. This can be a slip stream comprising an etheric derivative of the olefinic feed and an oligomeric derivative of the feed which is withdrawn from a subsequent step the process. This forms a separate hydrocarbon phase which is then extracted. The sulfates are then hydrolyzed to form alcohol.
