Advantage of Terephthalic Acid CAS No. 100-21-0

1. The most widely used and economical production method in industry is the high temperature liquid phase oxidation of p-xylene as raw material.

2. High temperature oxidation of p-xylene with acetic acid as solvent, cobalt acetate - manganese acetate as catalyst, tetrabromoethane as cocatalyst, p-xylene oxidation to terephthalic acid at 221-225℃, 2.5-3.0MPa.

3. Organic synthesis, determination of residual alkalinity of wool, gas chromatographic mop. Fatty acids can be separated and analyzed by adding polyethylene glycol 200.
