The invention provides a method for recovering a cyclosporine crude product from production waste liquid and the cyclosporine crude product, and relates to the technical field of
chemical separation engineering. The method for recovering the cyclosporine crude product from the production waste liquid comprises the following steps: concentrating the waste liquid; primary
crystallization; and performing secondary
crystallization and
drying. According to the method for recovering the cyclosporine crude product from the production waste liquid, 45%-65% of cyclosporine in the waste liquid can be recovered, and the method is very economical, practical and suitable for industrial production. According to the method, cyclosporine in the waste liquid is recycled, the recycled cyclosporine crude product can be put into cyclosporine refining production, the production cost of cyclosporine can be greatly reduced, and the method is simple in process
route, small in
material consumption and small in three-waste emission, and meets the requirements of economic, environmental and social progress.
