Diallyl phthalate is used to prepare vinyl ester resins with excellent electrical insulation properties, these are used to manufacture of electronics components. Alkyds are sometimes classes as phthalates, as they meet the technical definition, however, being polymeric esters of phthalic acid their properties … See more Phthalates , or phthalate esters, are esters of phthalic acid. They are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity. They are used … See more Phthalates are produced industrially by the acid catalysed reaction of phthalic anhydride with excess alcohol. The synthesis of diethyl phthalate is illustrative of this: The properties of the phthalate can be varied by changing the alcohol, allowing for an almost … See more The development of cellulose nitrate plastic in 1846 led to the patent of castor oil in 1856 for use as the first plasticizer. In 1870, camphor became the more favored plasticizer for cellulose nitrate. Phthalates were first introduced in the 1920s and quickly replaced … See more Due to the ubiquity of plasticized plastics, the majority of people are exposed to some level of phthalates.
