Distillates (petroleum), alkylate is a complex combination of hydrocarbons produced by distillation of the reaction products of isobutane with monoolefinic hydrocarbons usually ranging in carbon numbers from C3 through C5. It consists of predominantly branched chain saturated hydrocarbons having carbon numbers predominantly in the range of C11 through C17 and boiling in the range of approximately 205.degree.C to 320.degree.C (401.degree.F to 608.degree.F).
