A process for making non-phthalate, 1,2-phenylene oxo-diester plasticizers for polymer compositions, by selectively hydrogenating naphthalene to form a partially hydrogenated naphthalene, oxygenating said partially hydrogenated naphthalene to form phenylene diacids, and esterifying said phenylene diacids with oxo-alcohols to form 1,2-phenylene oxo-diesters. Also a process for making phenylene oxo-diester plasticizers by selectively brominating xylenes to form bisbromomethylbenzene, catalytic carboalkoxylation of the bromo-compound to form phenylene diacetate, followed by transesterification to form the phenylene oxo-diester.
一种制造非邻苯二甲酸酯、1,2-苯基氧代二酯增塑剂用于聚合物组合物的方法,通过选择性加氢萘形成部分加氢萘,将部分加氢萘氧化成苯基二酸,然后酯化苯基二酸与氧代醇形成1,2-苯基氧代二酯。另外一种制造苯基氧代二酯增塑剂的方法是通过选择性溴化二甲苯形成双溴甲基苯,催化羧酸酯化溴化合物形成苯基二乙酸酯,然后通过酯交换反应形成苯基氧代二酯。
