Phthalate

Diisobutyl Phthalate (DIBP) is prepared by esterification process of isobutanol and phthalic anhydride. Its structural formula is C6H4(COOCH2CH(CH3)2)2. Refractive index is 1.488 - 1.492 (20 °C, D).

Diisodecyl phthalate (DIDP) is a commonly used plasticizer used in the production of plastic and plastic coating to The coating on furnishings, cookware, pharmaceutical pills, food wrappers and many other products may have DIDP and other phthalates in them. There has been recent concern in the USA and European Union for their toxicity and bioaccumulative qualityincrease flexibility.

Diisononyl phthalate (DINP) is a phthalate used as a plasticizer. [2] DINP is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid.

Dimethyl terephthalate (DMT) is an ester of terephthalic acid and methanol and is used in the production of polyesters, including polyethylene terephthalate and polytrimethylene terephthalate. It consists of benzene with methyl ester groups attached in the para position, or to the first and fourth carbon atoms.

Potassium hydrogen phthalate, often called simply KHP, is a white or colorless, ionic solid that is the monopotassium salt of phthalic acid. The hydrogen is slightly acidic, and it is often used as a primary standard for acid-base titrations because it is solid and air-stable, making it easy to weigh accurately.

Dimethyl terephthalate (DMT) is an ester of terephthalic acid and methanol and is used in the production of polyesters, including polyethylene terephthalate and polytrimethylene terephthalate. It consists of benzene with methyl ester groups attached in the para position, or to the first and fourth carbon atoms.

Phthalates or phthalate esters, are esters of phthalic acid and are mainly used as plasticizers (substances added to plastics to increase their flexibility, transparency, durability, and longevity). They are primarily used to soften polyvinyl chloride.
