发明名称 Separation of methanol from mixtures containing it
摘要 A substantially anhydrous mixture of methanol with an organic compound with which it forms an azeotrope can be separated by dissolving into the mixture lithium chloride or other suitable salt that forms a complex with methanol so as to form a homogeneous mixture, adding an organic solvent that is miscible with the organic compound but immiscible with the complex and thereby forming a heterogeneous mixture, and separating the phases. The methanol can be recovered from one phase and the organic compound from the other. The organic compound may typically be methyl acrylate or methacrylate, the blend being, for instance, obtainable during the transesterification of methyl (meth)acrylate with an alcohol to form a higher boiling ester such as dimethylaminoethyl (meth)acrylate or 2-ethylhexyl acrylate.
