Storage method

50% gel suspension, 2kg plastic bottle, plus carton, net weight 20kg per box. Contact with alkaline substances should be avoided, stored in a cool place, and the packaging equipment should be sealed to prevent fire.

Synthesis method

It is derived from the condensation of trichloroacetaldehyde and monochlorobenzene in the presence of fuming sulfuric acid. Put trichloroacetaldehyde and chlorobenzene into the condensation pot, and add fuming sulfuric acid dropwise while stirring. The condensed material is allowed to stand for stratification, and the waste acid is discharged. The acidic DDT-chlorobenzene solution is washed with hot water and then with sodium hydroxide solution. Then the chlorobenzene is recovered by distillation, and the residue, namely molten DDT, is placed in a drum crystallizer for cooling and crystallization to obtain the finished product. The condensation reaction is carried out at 10-23°C. During the condensation, the waste acid produced by the condensation reaction (including p-chlorobenzenesulfonic acid generated by the side reaction) is added at the same time, or the side reaction is suppressed to reduce the amount of p-chlorobenzenesulfonic acid generated, and sulfuric acid is added dropwise. The time is about 2.5h. The para-position content of first-grade DDT raw powder is ≥74.0%.

Purpose

DDT was once one of the widely used pesticides. It has stomach poisoning and contact effects, and can be processed into powder, emulsion or oil. In our country, it was mainly used to control cotton bud and boll-stage pests, fruit tree borers, field crop armyworms, vegetable cabbage caterpillars, etc. It is also used for environmental sanitation and prevention of mosquitoes, flies, bed bugs, etc. DDT is not easily degraded into non-toxic substances, and it can easily accumulate during use and pollute the environment. DDT remaining in plants can enter the bodies of humans and animals through the “food chain” or other ways, causing poisoning and affecting human health. Its use is currently prohibited. However, some industrial uses of DDT, including pesticides using it as raw material, also require DDT as an intermediate, such as dicofol.

Properties and stability

The effect of estrogen can promote the development of secondary sexual characteristics and the final formation of sexual organs in underage girls. In adult women, in addition to maintaining the above-mentioned secondary sexual characteristics, it can also cause a series of changes in the endometrium to produce cyclic menstruation. It can also increase the activity of the uterus and fallopian tubes and increase the sensitivity of uterine muscles to oxytocin. In addition, estrogen can also increase the deposition of bone calcium salts and accelerate epiphyseal closure. In large doses, it can increase serum triglycerides and phospholipids, causing water and sodium retention. At larger doses, estrogen can also act on the hypothalamic-pituitary system, inhibit the secretion of gonadotropins and prolactin, and offset the main effects of androgens.

Storage method

This product should be sealed and stored in a dry place away from light.

Synthesis method

1. Use androst-4-en-19-desmethyl-3,17-dione to introduce bromine at the 2- and 6-positions through bromination, and then add bromine to 4-ethyl-2-methylpyridine In the presence of dehydrobromination (elimination), 2,4,6-androstatriene-19-desmethyl-3,17-dione is generated, which is then cracked at high temperature to generate estrone, and then lithium aluminum hydrogen is reduced to produce Get this product.

Purpose

1. Intermediates of estradiol valerate and estradiol benzoate.

2.Estrogen drugs. It is used for functional uterine bleeding, primary amenorrhea, menopausal syndrome and prostate cancer.
