Abstract
545,729. Separating ethyl chloride and butane. STANDARD OIL DEVELOPMENT CO. Oct. 23, 1940, No. 15575. Convention date, Nov. 3, 1939. [Class 2 (iii)] Ethyl chloride and butane are separated by treatment with a selective solvent such as methyl, ethyl, isopropyl or mixed alcohols or ethylene or propylene glycol, and particularly an aqueous ethyl alcohol. The process is particularly applicable for the separation of the azeotropic mixture obtained by distillation in the recovery of ethyl chloride in the formation of lead tetraethyl by heating under pressure a sodium lead alloy with excess of ethyl chloride preferably in presence of a catalyst such as pyridine or ethyl bromide. The mixture is fed through inlet 2 into a tower 1 maintained at from -10‹ C. to 100 ‹ C. and at a pressure which may be up to 200 lbs. per square inch, sufficient to maintain the material liquid, into a current of solvent from an inlet 3. The butane phase passes from the top of the tower to a recovery unit 5 where butane is separated preferably by distillation from the solvent. The solvent extract passes from the bottom of the tower to a recovery unit 10 where the ethyl chloride is separated preferably by distillation from the solvent. If ethyl alcohol is used as the solvent, the extract may be passed to a vessel 18 where it is treated with hydrogen chloride to form ethyl chloride from the alcohol. The selectivity of the solvent for ethyl chloride may be increased by addition of anti-solvents such as ethylene glycol or formamide.
