Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless, tasteless, and almost odorless crystalline chemical compound, [5] an organochloride. Originally developed as an insecticide, it became infamous for its environmental impacts. DDT was first synthesized in 1874 by the Austrian chemist Othmar Zeidler.

2025年3月6日 · DDT (dichloro-diphenyl-trichloroethane) was developed as the first of the modern synthetic insecticides in the 1940s. It was initially used with great effect to combat malaria, typhus, and the other insect-borne human diseases among both military and civilian populations.

6 天之前 · DDT, a synthetic insecticide that belongs to the family of organic halogen compounds and is highly toxic toward a variety of insects as a contact poison that apparently exerts its effects by disorganizing the nervous system. Learn more about DDT in this article.

2021年12月13日 · Dichlorodiphenyltrichloroethane (DDT) is a notorious insecticide that was considered to be a great scientific breakthrough. It goes by many other names, including the more formal 1,1’-(2,2,2-trichloroethylidene)bis(4-chlorobenzene) and 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane.

Dichlorodiphenyl-trichloroacetic acid (or DDT) is a chlorinated hydrocarbon that has been widely used as an insecticide. DDT is virtually insoluble in water , but is freely soluble in oils and in the fat of organisms. DDT is also persistent in the environment.

DDT is an organochlorine compound that was introduced for commercial use in 1945 and was used heavily in populated areas for vector control and in agriculture for pest control. DDT is an extremely persistent compound due to its near insolubility in water and tendency to bioaccumulate in fatty tissue and biomagnify throughout trophic levels.

DDT的化学名是二氯二苯基三氯乙烷，它并不是天然存在的物质，人们通过氯醛 ( CCl3CHO ) 和两个当量的氯苯 ( C6H5Cl )，在酸性催化剂下合成。 其实，DDT的发现历史非常悠久，早在1874年，奥地利化学家Othmar Zeidler就已经合成并提取了DDT。 不过，在接下来很长的一段时间里，人们并不知道这种东西可以用来当作杀虫剂。 随着工业革命的脚步，全球人口显著增长，提高粮食产量迫在眉睫，世界各地的研究团队为此寻找和合成了许多可以杀虫的化学物质。 然而，当时 …

When we refer to DDT, we are generally referring to p,p’-DDT, which was produced and used for its insecticidal properties. However, technical-grade DDT, the grade that was generally used as an insecticide, was composed of up to 14 chemical compounds, of which only 65–80% was the active ingredient, p,p’-DDT.

DDT, or dichlorodiphenyltrichloroethane, is a chemical compound with the formula C14H9Cl5. Learn about the properties of DDT along with its uses and the effects of this compound on human health Login

What are DDT, DDE, and DDD? DDT (dichlorodiphenyltrichloroethane) is a man-made chemical that does not occur naturally in the environment. It is a white, crystalline solid with no odor or taste . DDE (dichlorodiphenyldichloroethylene) and DDD (dichlorodiphenyldichloroethane) are chemicals similar to DDT that can form when DDT breaks down.
