Problems solved by technology

But owing to still having following problem: (1) used sieving step in one step of separation, needs to use a large amount of water like this, and then causes pollution, and simultaneously sieving process also can have part saponin loss; Filtration separation process steps, this technology consumes a lot of energy and is not very suitable for large-scale production requirements
(2) In the above-mentioned patent, the possibility of comprehensive utilization of the experiment is only pointed out, and how to implement it is not involved; in fact, there are still many specific problems in the process of implementation, such as: polysaccharides and monosaccharides in the solid slag after separation Coexistence brings difficulties to further utilization

Abstract

The invention discloses a clean manufacturing method and utilizing method of dioscin with low-pollution low-energy consumption and high-receiving rate, which is characterized by the following: utilizing slurry with rich polysaccharide; complementing alchol manufacturing technique through by-product; transmitting waste into industrial product partially; reducing pollution and improving economic benefit.

Description

Method for clean production and comprehensive utilization of diosgenin technical field The invention relates to the field of chemical product production, and more specifically relates to a method for clean production and comprehensive utilization of diosgenin. Background technique Dioscin is the basic raw material for the synthesis of hundreds of seedling drugs such as cortisone, prednisone, and dexamethasone. Dioscorea saponin is extracted from wild plant yam collar. Take diosminum scutellaria as an example, which contains 35-40% plant fiber, 45-50% starch, 10% water-soluble matter, and only 1-2.5% saponin content . The conventional process is to put the whole plant body into hydrolysis, 0.3N hydrochloric acid solution, and under the condition of 136°C, 85% of the substances are dissolved in acid water. An average of 70 tons of yams are used to produce 1 ton of saponin, and 25 tons of hydrochloric acid are consumed. The acid solution is filtered out, and the material is...
