Heptylates Chemical is a term that refers to a group of organic compounds that have the same molecular formula, C8H16O4, but different structures. These compounds are called isomers of bis(2-ethylhexyl) phthalate, or DEHP, which is the most common member of the class of phthalates that are used as plasticizers. DEHP is the diester of phthalic acid and the branched-chain 2-ethylhexanol. Heptylates Chemical is widely used in the manufacture of flexible polyvinyl chloride (PVC) products, such as flooring, tubing, medical devices, and toys. It is also used as a solvent, lubricant, and additive in cosmetics, paints, and adhesives. Heptylates Chemical is a colorless, oily liquid that is soluble in organic solvents but not in water. Heptylates are also involved in some chemical reactions, such as hydrolysis, oxidation, and transesterification. These reactions can produce different products, such as phthalic acid, 2-ethylhexanol, aldehydes, ketones, and other phthalate esters. Heptylates can also react with halogens, such as chlorine and bromine, to form halogenated derivatives.
