Reliance is at a disadvantage to its competitors because it makes its own raw material, purified terephthalic acid.
12.
Also as above, polyethylene terephthalate can be hydrolyzed to terephthalic acid and ethylene glycol under high temperature and pressure.
13.
The two monomer units used in producing this polymer are : 1, 3-propanediol and terephthalic acid or dimethyl terephthalate.
14.
AMOCO went on to become the world's largest manufacturer of terephthalic acid, and was later acquired by British Petroleum.
15.
The barium salt ( as its hexahydrate ) is very soluble ( a distinction between phthalic and terephthalic acids ).
16.
Yangzi supplies Yizheng with purified terephthalic acid ( PTA ), which accounts for about 60 percent of Yizheng's cost of sales.
17.
Rhodiaco is the sole producer in South America of a key raw material used in making polyester fiber, purified terephthalic acid.
18.
Virtually the entire world's supply of terephthalic acid and dimethyl terephthalate are consumed as precursors to polyethylene terephthalate ( PET ).
19.
Since approximately 40, 000, 000 tons of terephthalic acid are produced per year, CBA is a relatively large scale industrial chemical.
20.
This method is developed to reduce concentration of 4-carboxybenzaldehyde content in final product terephthalic acid to 200-300 ppm without separate purification step.
