Adding a certain compound to certain chemical reactions, such as: 626-43-7, name is 3,5-Dichloroaniline, belongs to chlorides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 626-43-7, 626-43-7
EXAMPLE 6; Preparation of 1,3,5-triaminobenzene from 3,5-dichloroaniline; hydrolysis with sulfuric acid of the 1,3,5-triaminobenzene to phloroglucinol, and purification; A pressurized vessel is charged with 30 g (18.6 mmol) of 3,5-dichloroaniline and 1.5 g of copper chloride in 160 ml of 28% aqueous ammonia. The mixture is heated at 190 C. and under a pressure of 37 bars for 24 hours. The contents of the vessel are poured into 200 ml of water and then the excess ammonia is removed. Then 37 g of 98% sulfuric acid are added and the mixture is heated at 110 C. for 20 hours. Following filtration, the solution is concentrated to a third and then cooled in an ice bath until the phloroglucinol precipitates. The precipitate obtained is subsequently recrystallized from 350 ml of a water-ethanol (93 V-7 V) mixture.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3,5-Dichloroaniline, other downstream synthetic routes, hurry up and to see.
