Description

technical field [0001] The invention relates to a compound synthesis device, in particular to a production device of polyoxypropylene polyoxyethylene glyceryl ether. Background technique [0002] Polyoxypropylene polyoxyethylene glyceryl ether is mainly used as a defoamer in the pharmaceutical industry. It is widely used in the production of oxytetracycline, tetracycline and other antibiotics to replace soybean oil for defoaming. The defoaming efficiency is 25 to 30 times higher than that of soybean oil, which can reduce the stock loss. Most of the existing production devices are relatively complicated. Polyoxypropylene polyoxyethylene glyceryl ether is used as a defoamer. The pros and cons of the production device have important economic significance for improving product quality and reducing by-product content. Contents of the invention [0003] The object of the present invention is to provide the production device of polyoxypropylene polyoxyethylene glyceryl ether, ma...
