Diethyl phthalate is produced by the reaction of ethanol with phthalic anhydride, in the presence of a strong acid catalyst: It finds some use as a specialist plasticiser in PVC, it has also been used as a blender and fixative in perfume. [3]

Phthalates can plasticise ethyl cellulose, polyvinyl acetate phthalate (PVAP) and cellulose acetate phthalate (CAP), all of which are used to make enteric coatings for tablet and capsule medications. These coatings protect drugs from the acidity of the stomach, but allow their release and absorption in the intestines.
Bis(2-ethylhexyl) phthalate (DEHP) also commonly known as (dioctyl phthalate, [12] DOP or diethylhexyl phthalate), historically used in flooring materials, medical devices, myriad consumer products, and high explosives, such as Semtex. DEHP was the most common plasticizer for decades and still holds that title globally even as it has largely ...
The most common way to prepare cellulose acetate phthalate consists of the reaction of a partially substituted cellulose acetate (CA) with phthalic anhydride in the presence of an organic solvent and a basic catalyst. The organic solvents widely used as reaction media for the phthaloylation of cellulose acetate are acetic acid, acetone, or ...
It is a phthalate and is the diester of phthalic acid and the 10-carbon branched-chain alcohol 2-propylheptanol. This colorless, viscous liquid is used for softening PVC plastics and is a general purpose PVC plasticizer. [2] It possesses very good plasticizing properties and may be used as a direct replacement for DEHP and DINP in many ...
[1] [2] In Ireland and the UK, the comparable preparation is surgical spirit B.P., which the British Pharmacopoeia defines as 95% methylated spirit, 2.5% castor oil, 2% diethyl phthalate, and 0.5% methyl salicylate. [3] Under its alternative name of "wintergreen oil", methyl salicylate is a common additive to North American rubbing alcohol ...
Bis(2-ethylhexyl) phthalate (di-2-ethylhexyl phthalate, diethylhexyl phthalate, diisooctyl phthalate, DEHP; incorrectly — dioctyl phthalate, DIOP) is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. DEHP is the most common member of the class of phthalates, which are used as plasticizers.
