Title:
SEPARATION OF ALKANOL FROM ETHER
Document Type and Number:
Japanese Patent JPS5630934
Kind Code:
A
Abstract:
A C1-C3 alkanol is separated from an ether corresponding to the formula R-O-R', wherein R is an alkyl group containing 1-3 carbon atoms and R' is a t-butyl or t-amyl group, by intimately mixing the alkanol-ether mixture with at least 0.25 mol of calcium chloride per mol of alkanol. The calcium chloride is preferably used as an aqueous solution. The intimate admixture leads to the formation of a calcium chloride-alkanol complex corresponding to the formula CaCl2. ROH which is easily separated from the ether. The invention is particularly useful for extracting methanol from the crude reaction product obtained by reacting an excess of methanol with isobutylene or a C4 hydrocarbon stream containing isobutylene to form methyl t-butyl ether.
