| use | Didecyl phthalate is the primary plasticizer for vinyl resins and has also been shown to be compatible with polystyrene and cellulose. |
| application | Didecyl phthalate has low volatility, only one-fourth that of dioctyl phthalate (DOP), and has low migration and good extraction resistance. It can be used as a plasticizer for vinyl resin and cellulose resin. It is also used as gas chromatography stationary liquid. The maximum operating temperature is 150°C. The solvent is acetone, chloroform or methanol. It can selectively retain and separate aromatic compounds, unsaturated compounds and various oxygenated compounds (alcohols, aldehydes, ketones and esters). etc.), halogenated hydrocarbons and hydrocarbon compounds below G. |
| Prepare | Didecyl phthalate is synthesized from the esterification of phthalic anhydride and decanol. The production method of phthalate plasticizer is relatively common, see the production method of dioctyl phthalate (C24H38O4, [117-84-0]). In actual industrial products, there is no complete linear chain didecyl phthalate, but a mixture of branched chain esters, but the proportions of isomers are different. |
| definition | ChEBI: Di-n-decyl phthalate is a phthalate ester and diester. |
