Product: 2-tert-butylhydroquinone (MTBHQ）
Chemical Name: tertiary butylhydroquinone、tert-Butylhydroquinone or mono-tert-Butylhydroquinone
Chemical Formula：C10H14O2
Molecular Weight：166.22
CAS: 1948-33-0
EINECS Number: 217-752-2
Product Introduction
At a concentration of 0.01%-1.0%, MTBHQ is a very effective antioxidant for unstable organic liquids (such as fluorohydrocarbons, oils, aldehydes and aldehydes). Used as a polymerization inhibitor, light and heat stabilizer and industrial antioxidant for polymers, MTBHQ is more effective than hydroquinone, it has higher solubility and higher efficiency at high temperatures, and is more useful than hydroquinone wide。
Application
1. Anti-aging agent in rubber and plastic industry
2. PVC additives (anti-fisheye agent)
3. Used in pharmaceutical intermediates and organic synthesis
4. Stabilizer: Prevent oxidation of resin and other substances
5. It can be used as an antioxidant in industrial oils (such as lubricating oil), fatty acid esters of oil, linseed oil and other greases, as well as in inks, pigments, dyes, and pharmaceutical intermediates.
