Title: Glycidol isolation by azeotropic distillation with a lower-boiling entrainer
IPC: C07D301/32
Filed: 1971-03-23
Abstract: This specification discloses a process for isolating glycidol from a solution in a solvent which boils above 126 DEG C. and which forms a low-boiling azeotrope with glycidol that is homogeneous when condensed and cooled to room temperature. The glycidol separation is affected by adding to this solution, tetrachloroethylene or a liquid aliphatic, cycloaliphatic or chlorinated aliphatic hydrocarbon these additives form even lower boiling azeotropes with glycidol, and the lower boiling azeotrope can be distilled away from the original solvent. The noted additives have the property that their lower boiling azeotropes with glycidol, upon condensation and cooling, separate at 20 DEG to 40 DEG C. and even above, into two phases one phase is rich in glycidol and the second phase contains relatively little glycidol. The two phases can be easily separated, for example, by decantation. If glycidol of higher purity than that of the glycidol-rich phase is desired, it may be obtained by distillation of that phase.
