Description

Product Details

Chemical name: Pyrogallol; Pyrogallic acid

Other name: 1,2,3-trihydroxybenzene

Appearance: white crystalline powder

Molecular formula: C6H3 (OH) 3

Molecular weight: 126.11

Melting point: 309 ° C

CAS No.: 87-66-1

Product introduction

Pyrogallic acid is a chemical reagent and chemical raw material with multiple uses, widely used in pharmaceutical synthesis, dyes, food, pesticides and electronic products, as a developer, heat sensitive agent, auxiliary agent of polymer materials, chemical analysis reagent, etc., and in some fields, it can not be replaced by other products. At present, the main raw material for producing pyrogallic acid is gallic acid. Gallic acid is obtained by hydrolysis of gallnut or tara, a forest product. Galla is a special product of China, with good quality and large quantity (the output accounts for about 1/4 of the world output). Therefore, it has great economic and social benefits to do a good job in the deep processing of Chinese nutgall.

This product is a white luster crystal, with a melting point of 131~134 ℃, a boiling point of 309 ℃, a relative density of 1.46, and UV when pH=5.4 in water λ max2. 88nm。 Easily soluble in water, alcohol and ether, slightly soluble in benzene, chloroform and carbon disulfide. Heating can sublimate. Exposed light or in the air will become brown. When the solution is alkaline, it will soon absorb oxygen and change color. Packaging: The products are packed in cardboard drums, each with a net weight of 25kg.

Application

1. Cosmetic additives

2. Important catalysts and additives in chemical industry

3. In medicine, strong reducing agent, fungicidal

4. One of the important feed formulas

5. High efficiency and low residue insecticide

6. New imaging materials, metallurgical flotation agents
