It is a non-phthalate plasticiser, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol. This colorless viscous liquid used for softening PVC plastics is known for chemical similarity to general purpose phthalates such as DEHP and DINP, but without any negative regulatory pressure. It possesses very good plasticizing properties and may be used as a direct replacement for DEHP and DINP in many applications. ==Production== The process entails the reaction of dimethyl terephthalate with 2-ethylhexanol: :C6H4(CO)2(OCH3)2 + 2 C8H17OH → C6H4(CO2 C8H17)2 + 2CH3OH 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Dioctyl terephthalate」の詳細全文を読む スポンサード リンク
