Tetradecanedioic Acid CAS 821-38-5 TDA

Tetradecanedioic acid is an important industrial product among the long chain dibasic acids.It is mainly used in the synthesis of polymer materials, spices, drugs and so on.For example, as the main raw material for the synthesis of musk ketone, the raw material for the synthesis of high performance lubricants with special performance requirements of long carbon chain dibasic acid dibasic ester, the synthesis of high-performance polyamide hot-melt adhesive condensation monomer, as well as as the polymerisation of polymerisation monomer and diamine polymerisation reaction to synthesize the long carbon chain nylon, with tetradecanedioic acid as the raw material, as a polymerization monomer and the diamine polymerisation reaction to synthesize the long carbon chain nylon, the main ones areNylon 1314, nylon 1414 and nylon 614, etc.
