Esterification of 5-Norbornene-2,3-Dicarboxylic Anhydride under Titanium Catalyst
Abstract:
Norbornene dicarboxylate was synthesized through esterification under titanium catalyst. The alcohols are 2-ethyl-1-hexanol, n-octanol, 3,5,5-trimethyl-1-hexanol, and n-decanol. The Structures of compounds were identified by 1H-NMR, and then components were identified by high performance liquid chromatography (HPLC). The yield and purity was over 90 % and 95 %, and color of compounds was colorless or light yellow. The maleate as a by-product was occured by the retro Diels-Alder reaction.
