Problems solved by technology

[0002] At present, the preparation of glucose and alcohols is mainly made of corn, and the by-products produced during the preparation process cannot be rationally utilized. For example, the produced corn sugar dregs and corn alcohol dregs, whether liquid or solid, used to belong to industrial Waste materials cannot be utilized, and how to safely and harmlessly dispose of these waste materials is also an industry problem; therefore, there is an urgent need for a method for preparing biomass phthalic anhydride polyols by utilizing corn deep processing by-products

Abstract

The invention relates to a preparation method of a biomass phthalic anhydride polyol. The preparation method comprises the steps of 1) feeding 20-130 parts by weight of corn sugar residue, 0-0.9 part by weight of B-glucanase, 0-0.6 part by weight of cellulase and 5-90 parts by weight of water into a reactor, next, increasing the temperature of the reactor to the range from 40 to 65 DEG C, stirring for reacting for 1-6 hours and then obtaining a liquid corn sugar residue zymolyte; and 2) feeding the liquid corn sugar residue zymolyte obtained in the step 1), biomass diglycol, phthalic anhydride, butyl titanate, propylene glycol, corn alcohol residue, antimony acetate, biomass glycerol and castor oil in parts by weight into the reactor, increasing the temperature of the reactor to the range from 140 to 215 DEG C, reacting for 4-6 hours and obtaining the biomass phthalic anhydride polyol. The preparation method of the biomass phthalic anhydride polyol is simple in steps, capable of rationally utilizing the side product of corn deep processing, and simple in process; the prepared biomass phthalic anhydride polyol is stable in physical properties, and can be used as a novel foam material, and further is not easy to deform; and therefore, reutilization of wastes can be realized, which is advantageous for environmental protection.
