Abstract

The invention discloses a method for preparing octenylsuccinate hydroxyethyl bean-dreg cellulose ester from hydroxyethyl bean-dreg cellulose and octenyl succinic anhydride, which comprises the following steps: dissolving hydroxyethyl bean-dreg cellulose in a water / ethanol system to form a silt state, carrying out an esterification reaction with octenyl succinic anhydride in an alkaline environment, washing with ethanol, drying and pulverizing to obtain the product. The product is light yellow powder, has the advantages of no peculiar smell and high solubility, and has certain emulsibility and surface activity. The preparation method provided by the invention has the advantages of cheap and easily obtained raw material (bean dregs), and low production cost, is simple and easy to operate, can increase the added value of the bean dregs, and partially solves the problems of waste of resources and environmental pollution caused by waste bean dregs.

Description

technical field

[0001] The invention relates to the modification of okara cellulose, in particular to the preparation of octenyl succinic acid hydroxyethyl okara cellulose ester. Background technique

[0002] my country is the main country that grows soybeans in the world, and it is also the main consumer country of soybeans. It has rich experience and relatively mature technology in soybean processing and treatment. Because soybeans are rich in various nutrients, the soybean processing industry is booming and in the ascendant. With the increase of soybean processing, the output of the main by-product bean dregs in the processing technology is also increasing day by day. Due to the poor taste of bean dregs and high water content, it is not easy to store, so except that some bean dregs are used as animal feed, most of the bean dregs are not obtained. Making full use of them will not only cause waste of resources, but also cause environmental pollution.

[0003] There are ma...
