Abstract
Methyl borate is separated from an azeotrope with methanol by mixing the azeotrope with a mineral oil in which methyl borate is soluble and methanol is substantially insoluble, settling the mixture to form a layer comprising a solution of methyl borate in mineral oil and a methanol layer, separating the mineral oil layer from the methanol layer, subjecting the mineral oil layer to distillation, e.g. flash distillation, to drive off methyl borate, passing the methyl borate to a fractionating column, taking off methyl borate from the bottom of said column, and taking off as overhead from the column in the form of an azeotrope with methyl borate the methanol present in the feed to the column. The azeotrope removed overhead may be recycled for further treatment with the mineral oil, which may also be recycled from the distillation step.ALSO:Methyl borate is separated from an azeotrope with methanol by mixing the azeotrope with a mineral oil in which methyl borate is soluble and methanol is substantially insoluble settling the mixture to form a layer comprising a solution of methyl borate in mineral oil and a methanol layer, separating the mineral oil layer from the methanol layer, subjecting the mineral oil layer to distillation, e.g. flash distillation, to drive off methyl borate, passing the methyl borate to a fractionating column, taking off methyl borate from the bottom of said column, and taking off as overhead from the column, in the form of an azeotrope with methyl borate, the methanol present in the feed to the column.
