The main raw materials are described as follows: Purified terephthalic acid (PTA) CAS-No.: 100-21-0, Synonym: 1,4 benzenedicarboxylic acid. Sum formula: C6H4(COOH)2, mol. weight: 166.13,Dimethylterephthalate (DMT) CAS-No.: 120-61-6.
Synonym: 1,4 benzenedicarboxylic acid dimethyl ester, Sum formula: C6H4(COOCH3)2, mol. weight: 194.19.
Mono-ethylene glycol (MEG) CAS No.: 107-21-1, Synonym: 1,2 ethanediol,Sum formula: C2H6O2 , mol. weight: 62.07.
To make a polymer of high molecular weight a catalyst is needed. The most common catalyst is antimony trioxide :Antimony trioxide (ATO) CAS-No.: 1309-64-4, mol. weight: 291.51, Sum formula: Sb2O3
In 2008, about 10,000 tonnes Sb2O3 were used to produce around 49 million tonnes polyethylene terephthalate.
Polyester is described as follows: Polyethylene terephthalate CAS-No.: 25038-59-9, Synonyms/abbreviations: polyester, PET, PES,
Sum formula: H-[C10H8O4]-n=60–120 OH, mol. unit weight: 192.17.
