Separation of glycol dialkyl ethers from monoalkyl ether |
| abstract |
A procedure is provided for the separation of close boiling impurities from products which have slightly higher polarity than the impurities, for example, separation of di-propylene glycol di-tert-butyl ether (DE) from di-propylene glycol mono-tert-butyl ether (DPTB) by distillation, water or steam being used as stripping component with heat provided by a reboiler. |
