Abstract
Trimethyl borate and methanol are separated from azeotropic and non-azeotropic mixtures thereof by distillation from a still equipped with a reflux column, an organic solvent of boiling-point between 100 DEG and 275 DEG C. being introduced into the column during the distillation to inhibit selectively the distillation of one of the components. Non-polar solvents inhibiting the distillation of trimethyl borate from its mixtures with methanol are exemplified by paraffinic hydrocarbons of from 8 to 15 carbon atoms per molecule, e.g. octane and decane, and mixtures thereof, e.g. kerosene; aromatic hydrocarbons containing one or two non-fused aromatic nuclei, and their halogen and short-chain alkyl derivatives, e.g. biphenyl, xylene and dichlorobenzene; and ethers whose organic radicals are mononuclear aromatic radicals, e.g. diphenyl ether. Polar solvents inhibiting the distillation of methanol from its mixtures with trimethyl borate, and whose molecules contain an unshared pair of electrons on an atom of oxygen, nitrogen or sulphur, are exemplified by mono- or di-alkyl N-substituted formamide, acetamide, or propionamide, the alkyl group or groups containing either 1 or 2 carbon atoms; dimethylsulphoxide; phenol and short-chain alkyl derivatives of phenol, e.g. cresol.
