Terephthaloyl chloride: a key precursor for high-performance fibers

In chemical fiber plants and laboratories, terephthaloyl chloride (TPC), a special chemical, is quietly driving the progress of materials science. As an important diacyl chloride compound, it has become the core raw material for the preparation of a variety of high-performance polymers.

Why is TPC irreplaceable in material synthesis?

The key is that both ends of its molecular structure carry highly active acyl chloride groups, which can undergo condensation reactions with various amine compounds. This property makes it an ideal monomer for the preparation of high-performance fibers such as aramid and polyamide. In particular, when making para-aramid fibers, the polymerization reaction of TPC and paraphenylenediamine can form a rigid molecular chain structure, giving the material extraordinary strength.

The materials developed based on TPC have three outstanding properties:

1. Excellent thermal stability, with a decomposition temperature exceeding 500℃

2. Mechanical strength is 5-8 times that of steel wire

3. Excellent chemical corrosion resistance

From bulletproof vests to optical cable reinforcements, from high-temperature filter felts to aerospace composites, high-performance materials derived from TPC are playing an important role in key areas. This seemingly simple chemical molecule is actually an important bridge connecting basic chemicals and cutting-edge materials.
