Reduction of the viscosity of the high molecular weight by-products in the production of 1,3-propanediol

摘要

In this process, improves the production of 1,3-propanediol in the form of an aqueous solution of 3-hydroxy propanal formation, if used in The Catalyst is removed from the solution and Sodium hydroxide was added to NEUTRALIZE The Acid present in any way Such that the PH is at least 5The neutralized aqueous solution is subjected to a hydrogenation to produce 1,3-propanediol mixture is distilled to produce 1,3-propanediol, Water, and reactive compounds of high molecular weight.Improving this process includes replacing the Sodium hydroxide and the hydroxide selected AMMONIUM HYDROXIDE, alkali metal hydroxides than Sodium hydroxide of alkali earth metal hydroxides, and to reduce the viscosity of the reactive compounds of High Weight mo Lecular.
