Process of separating 1-methoxy-2-propanol and 2-methoxy-1-propanol from aqueous compositions

摘要

The present invention refers to process of separating 1-methoxy-2-propanol and 2-methoxy-1-propanol from aqueous compositions, comprising: dewatering of the aqueous composition comprising 1-methoxy-2-propanol and 2-methoxy-1-propanol to a concentration of 1-methoxy-2-propanol and 2-methoxy-1-propanol of at least 90 percent by weight in total and isolation of 1-methoxy-2-propanol, 2-methoxy-1-propanol or mixtures thereof by means of distillation.
