Toluene → 2,2-Dimethyl-3-hydroxypropanal trimethylolethane

참여 물질

반응 단계

102.1 parts of 2,2-dimethyl-4-hydroxypropanal, 120 parts of trimethylolethane, 5 parts of p-toluenesulfonic acid and 400 parts of toluene were charged in the same reactor as in Synthesis Example 1. The reaction was carried out in the same manner as in Example 1 until 18 parts of water was formed. The reaction temperature was 92° to 115° C. The solvent was distilled off under reduced pressure and the residue was filtered out and then purified to obtain 2,2-dimethyl-3-hydroxypropanal/trimethylolethane condensate. The condensate was a white solid having a hydroxyl value of 549.9 and melting point of 127° to 129.5° C.
