Abstract
This paper discusses the synthesis of 2-methyl-2-pentena from self-Aldol condensation of propionaldhyde,with hydroxide sodium solution as the catalyst of the condensation.The optimum conditions are established:reaction temperature is 293K,the number of benzene as the solvent is 5ml,the concentration of catalyst 2M,reaction time is 1h,NaOH:CH 3CH 2CHO(mol/mol)=2:15,and 2-methyl-2-pentenal can be obtained with 98.4% yields.
