Phthalates are the esters of 1,2-dibenzene dicarboxylic acid; their general structure is given in Figure 1. They are produced by the addition of an excess of branched or normal alcohols to phthalic anhydride in the presence of a catalyst.

Phthalates are a group of chemicals used to make plastics more durable. They are often called plasticizers.

They are not chemically bound to plastics, so they can be released from consumer products into the environment and may result in human exposure. There is public concern about phthalates because of their widespread use, including in products for children, and their potential effects on human health.

Phthalates, a family of industrial chemicals used to soften polyvinyl chloride (PVC) plastic and as solvents in cosmetics and other consumer products, can damage the liver, kidneys, lungs, and reproductive system.

Phthalates have been found in dairy products, meats, fish, oils & fats, baked goods, infant formula, processed foods, and fast foods. This is true even if the food is organic. Phthalates are added to some food packaging and to materials used to handle and process food.

A: In 2017, the Consumer Product Safety Commission banned the use of eight ortho-phthalates in children’s toys and child-care articles. But in terms of their use in vinyl plastics and personal care products, there’s currently no specific legislation by other governmental agencies.

We have a balanced chemical equation in which we now know the exact quantity of one of the reagents (KHP) – NaOH(aq) + KHC8H4O4(aq) = KNaC8H4O4(aq) + H2O(l) – thus we can determine the number of moles of NaOH that reacted with the KHP….Stoichiometry and Solutions.

Potassium hydrogen phthalate, often called simply KHP, is an acidic salt compound. It forms white powder, colorless crystals, a colorless solution, and an ionic solid that is the monopotassium salt of phthalic acid.

For all phthalates the most abundant ion in the mass spectra was m/z 149, corresponding to the protonated phthalic anhydride ion [C 8 H 5 O 3] +●, except for dimethylphthalate, which gave a base ion at m/z 163 [M-31] +●. However, when analysing phthalate mixtures better group profiling is needed with more characteristic ions.

Phthalate(2-) is a phthalate that is the dianion obtained by the deprotonation of both the carboxy groups of phthalic acid. It has a role as a human xenobiotic metabolite. It is a conjugate base of a phthalate(1-).

Phthalates are a group of chemicals used in hundreds of products, such as toys, vinyl flooring and wall covering, detergents, lubricating oils, food packaging, pharmaceuticals, blood bags and…
