Production technology of abamectin

Abstract

The invention discloses a production technology of abamectin. The technology comprises the following production steps of S1, performing strain culture: firstly culturing a strain, placing the strain on a culture shelf for culture work, then producing an inclined plane on the surface of the strain after the culture is completed so as to downwards drip a bacterial suspension, and collecting the bacterial suspension; and S2, performing fermentation: culturing the collected bacterial suspension, and adding a corresponding culture solution. By adopting the technology different from a traditional abamectin processing technology, a crystallization processing mode is improved in the production process, and a three-time crystallization mode is adopted, so that the purity of mycelia can be greatly improved; and two processes of leaching and desugaring are additionally added in two processes of fermentation and crystallization, so that impurities in the mycelia can be removed before the mycelia are crystallized; and particle impurities and other components in the mycelia are removed, so that the crystallized mycelia can be purer, and the production process is more reasonable.

Description

technical field [0001] The invention relates to the technical field of chemical substances, in particular to a production process of abamectin. Background technique [0002] Abamectin is a chemical substance, its molecular formula is C49H75NO13; C48H73NO13, the original drug is white or light yellow crystalline powder, the melting point is 141-146 ° C, soluble in acetone and methanol, slightly soluble in water, insoluble in hexane, when stored Stable under normal storage conditions, its toxicity and poisoning symptoms: high toxicity of the original drug, low toxicity of the preparation, almost non-toxic; early symptoms after poisoning are dilated pupils, movement disorders, muscle tremors, vomiting in severe cases, and accidental poisoning. Induce vomiting immediately and give the patient either syrup of ipecac or ephedrine. [0003] When the existing abamectin is produced, the entire processing and production process is relatively simple, which leads to the fact that the p...

AI Technical Summary

Problems solved by technology

[0003] When the existing abamectin is produced, the entire processing and production process is relatively simple, which leads to the fact that the purity and quality of the mycelium itself are prone to substandard situations during subsequent production, so that after the finished product is produced It is prone to a large number of defective products, which cannot meet the high-quality requirements of products during production
