Open publisher page 1 citations

Abstract

Trimethylolpropyl triacrylate(TMPTA) was synthesized using trimethylolpropane and acrylic acid as the raw materials.Using hydroquinone as the inhibitor,the optimum synthesizing condition of TMPTA with yield of 88.3% was obtained through orthogonal experiment and single factor experiment and as followes:mole ratio of trimethylolpropane to acrylic acid 1:4.2,the reaction temperature 80 ℃,the reaction time 4 hours.The chemical structure of TMPTA was characterized by FT-IR and 1H NMR.The purity of TMPTA measured by high performance liquid chromatography was 95%.
