Uses and synthesis of 1,2-Phenylenediamine powder

1,2-Phenylenediamine powder is also known as 1,2-diaminobenzene and 1,2-phenylenediamine. White to light yellow leafy crystals when precipitated from water, prismatic crystals when precipitated from chloroform. 1,2-Phenylenediamine CAS 95-54-5 Changes colour easily when exposed to air, from white to yellow, brown, violet, and finally black. 1,2-Phenylenediamine Raw Materials Slightly soluble in cold water. Slightly soluble in cold water (4.15 at 35℃), easily soluble in hot water (733 at 81℃), ethanol, ether, chloroform and benzene.

Applications / Functions of 1,2-Phenylenediamine powder

1. 1,2-Phenylenediamine powder is used as the intermediate of cationic dyestuff, and is the main raw material of the pesticide carbendazim and other antifungal agents.
2. 1,2-Phenylenediamine CAS 95-54-5 Used as analytical reagent, fluorescent indicator, also used in organic and dye synthesis
3. Used as pesticide, medicine, dye intermediates
4. 1,2-Phenylenediamine Raw Materials is the intermediate of fungicide carbendazim, thiophanate-methyl, thiabendazole, and also the intermediate of insecticide quinalphos, and it is an important intermediate in dye industry.

Physicochemical Property of 1,2-Phenylenediamine powder

Colourless monoclinic crystals, darkening in air and sunlight. Slightly soluble in cold water, more soluble in hot water, easily soluble in ethanol, ether and chloroform.

Production methodprocess of 1,2-Phenylenediamine powder

o-Nitroaniline and sodium sulphide reduction method React with o-Nitroaniline and sodium sulphide solution under the pressure of 98~196kPa, reaction temperature of 105~110℃, and also under the reaction temperature of 120~130℃ and atmospheric pressure, the reaction time is 3~4h, to get 1,2-Phenylenediamine powder.

O-Nitroaniline Hydrogenation Reduction Method Using o-nitroaniline as raw material and Lanny nickel as catalyst, the reaction was carried out in an autoclave at a controlled temperature of 95~105℃, and hydrogen was passed continuously until the pressure did not drop, and the reaction was stirred at a pressure of 1.960MPa to obtain 1,2-Phenylenediamine CAS 95-54-5.
