INNOVATIVE PROCESS TO SEPARATE MONO-OLS AND POLYOLS FROM THE AQUEOUS STREAM USING REACTIVE EXTRACTION TECHNOLOGY

摘要

The present invention deals with separation of mono-ols polyols from the aqueous stream by reactive extraction technology. In many of the chemical processes, mono-ols and polyols remain in the aqueous phase. Because of their high solubility in water, separation of these compounds is difficult. The conventional method for recovering these compounds is to evaporate water from the solution, distillation or evaporative crystallization. Because of incorporation of distillation or evaporation step, the process of separation of mono-ols and polyols becomes very energy intensive. In this innovation mono-ols and polyols are converted to their corresponding acetals / ketals & are separated from the aqueous stream.
