| Abstract: | Glutaraldehyde was synthesized by oxidation of cyclopentene with 30% aqueous solution of hydrogen peroxide.Effects of the dosage of catalyst,reaction temperature,reaction time and solvents were discussed.The results showed that the highest yields of glutaraldehyde(dosage of catalyst composite H 2WO 4 B 2O 3 0 534%,temperature 35 ℃,time 22 h) were 62 5%,63 7%,and 56 2% when t butyl alcohol,i propyl alcohol,and n butanol were used as the solvents respectively. |
