| titleOfInvention | Preparation method of magnetic solid acid catalyst and extraction process of saponin |
| abstract | The invention provides a preparation method of a magnetic solid acid catalyst and a saponin extraction process. The magnetic solid acid is used as a catalyst to hydrolyze diosgenin, the catalytic performance is high, and the magnetic adsorption can be separated, recovered and reused, and the aqueous solution can be recovered and reused during hydrolysis. , can avoid a large number of discharges with high acidity and high organic concentration due to strong acid hydrolysis, and greatly reduce the environmental pollution caused thereby; Efficient use of turmeric resources, the entire process can obtain saponin, using double separation method to separate out The cellulose and starch in turmeric can greatly reduce the problem of extremely high COD in the mother liquor caused by the hydrolysis of cellulose and starch. At the same time, starch can be recovered. As a raw material for the wine industry, cellulose can be used as a compound fertilizer raw material for the extraction of turmeric soap. It provides a clean and efficient production process route; in order to minimize the discharge of waste liquid and slag, a circulating water process is adopted in the process route to achieve clean production. |
