乙酰甲胺磷是广谱、低毒杀虫剂,但国内需求量并不大,目前供需基本保持平衡,每年还有少量出口。现在国内乙酰甲胺磷年产量为5000-6000吨。如果新建、扩建装置全部建成投产,年生产能力将达到30000吨,将造成产品大量积压。国内乙酰甲胺磷生产水平较低,以甲胺磷计,乙酰化收率不到90%,母液经结晶得到的工业 Acetomethamine is a broad-spectrum, low-toxic insecticide, but domestic demand is not large. Currently, supply and demand are basically balanced, and there is still a small amount of exports every year. At present, the annual output of acephate is 5000-6000 tons. If all new and expansion devices are completed and put into production, the annual production capacity will reach 30,000 tons, which will cause a large backlog of products. The domestic acephate production level is relatively low, with methamidophos, the acetylation yield of less than 90%, the mother liquor obtained by the crystallization of the industry
