Benzoic Acid
CAS NO.: 65-85-0
Molecular Formula: C₇H₆O₂
Molecular Weight: 122
The benzoic acid is a colorless crystalline solid and a simple aromatic carboxylic acid. And it is an important precursor for the industrial synthesis of many organic substances. The salts and esters of benzoic acid are widely known as benzoates. Usually, the benzoic acid is classified into industrial grade, pharmaceutical grade and food grade benzoic acids. It is the precursor to many substances, like plasticizers, sodium benzoate and related preservatives, benzoyl chloride.
Main Applications:
The benzoic acid is widely used as preservative in a wide selection of industrial applications, like antimicrobial agent of latex, toothpaste, jam, dyeing and printing mordants, pharmaceutical and dyeing intermediates to prepare plasticizer, spices and rust inhibitor of steel equipment, etc. Also it serves as a building block for the synthesis of alkyd resins.
Snowhite benzoic acid products are classified into:
- Benzoic acid tech grade
- Benzoic acid food grade
- Benzoic acid feed grade
- Benzoic acid pharmaceutical grade
