- W2391260004 abstract "With catalyst,formaldehyde and butanal in turn after aldol condensation and hydrogenation reaction,trimethylolpropane (TMP) was synthesized.Aldol condensation reaction used triethylamine as catalyst and hydrogenation reduction reaction with palladium carbon as the catalyst.The factors influencing aldol condensation reaction and the hydrogenation reduction was studied by changing the single variable.The research showed that when the ratio of formaldehyde, butanal and triethylamine was 2.3:1.0:0.55,yield of TMP can reach 47.5%.The optimal reaction conditions were aldol condensation temperature 65℃,reaction time 4 h and the hydrogenation pressure 5 MPa,temperature 120℃and high pressure reaction kettle stirring rate 550 r/min." @default.
