Diallyl phthalate wikipedia
Phthalates are colorless, odorless liquids produced by reacting phthalic anhydride with an appropriate alcohol (usually 6- to 13-carbon). The mechanism by which phthalates and related compounds effect plasticization to polar polymers has been a subject of intense study since the 1960s. [46] 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 … 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, See more Phthalates are easily released into the environment. In general, they do not persist due to rapid biodegradation, photodegradation, and anaerobic degradation. … See more Due to the ubiquity of plasticized plastics, the majority of people are exposed to some level of phthalates. For example, most Americans tested by the Centers for Disease Control and Prevention See more PVC Plasticisers Between 90 and 95% of all phthalates are used as plasticisers for the production of flexible PVC. They were the first commercially important compounds for this role, a historic advantage that has led to them becoming … See more Phthalate esters are the dialkyl or alkyl aryl esters of phthalic acid (also called 1,2-benzenedicarboxylic acid, not be confused with the structurally isomeric terephthalic or isophthalic acids); … See more WebDibutyl phthalate ( DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range.
