Abstract: A NEW POLYMERIC ORGANO ALUMINUM SUBSTANCE IS DESCRIBED; IT HAS ESSENTIALLY THE STRUCTURAL FORMULA:

(CH3-)2-AL-(CH2-AL(-CH3))N-CH3

WHEREIN N DENOTES AN INTEGER OF AT LEAST 2, THE UPPER LIMIT BEING PRACTICALLY INFINITY. THE SUBSTANCE AND BRANCHED DERIVATIVES THEREOF MAY BE PREPARED BY DISSOLVING BICYLOPENTADIENYLTITANOMONOMETHYL CHLORIDE IN TRIMETHYL ALUMINUM AND THE WHOLE KEPT THERMOSTATICALLY AT -50 TO 200*C. WHILE EXCLUDING OXYGEN AND WATER AND EVOLVING METHANE.

Abstract: 1,3-Butadiene is recovered with the aid of a selective solvent from a C4-hydrocarbon mixture containing 1,3-butadiene, hydrocarbons which are more soluble in said selective solvent than 1,3-butadiene, including acetylenes and possibly 1,2-butadiene and C5-hydrocarbons, and hydrocarbons which are less soluble in said selective solvent than 1,3-butadiene. The C4hydrocarbon mixture is separated by the use of one or more extractive distilling zones into 8 distillate containing the less soluble hydrocarbons, a stream consisting of 1,3-butadiene and a stream containing the more soluble hydrocarbons including the higher acetylenes and 1,3-butadiene, the latter stream being subjected to catalytic hydrogenation.
