Di Octyl Phthlate

Supported by knowledgeable experts, we are importing, trading, distributing, manufacturing and supplying an excellent quality collection of Di Octyl Phthlate in Coimbatore, Tamil Nadu, India. DOP softener oil available in 210 kilograms sealed drums. Also known as kanatol 800 widely used as a plasticizer in manufacturing of articles made of PVC.[4] Plastics may contain 1% to 40% of DEHP. It is also used as a hydraulic fluid and as a dielectricfluid in capacitors. DEHP also finds use as a solvent in glowsticks.

Approximately three billion kilograms are produced annually worldwide. It is estimated that at least 241 million pounds of DEHP were produced in the US in 1999.

Industrial production entails the reaction of phthalic anhydride with 2-ethylhexanol:

C6H4(CO)2O + 2 C8H17OH a C6H4(CO2 C8H17)2 + H2O
2-Ethylhexanol is chiral, and the resultant DEHP consists of a mixture of (R,R)-, (S,S)-, and (R,S)-isomers (left).

PVC is used extensively in sewage pipe due to its low cost, chemical resistance, and ease of jointing. Phthalate plasticizers are essential to the utility of PVC, which is otherwise too brittle.
