| Abstract: | The manupacturing process of 25% glutaraldehyde solution from dicyclopentadiene via gasphase depolymerization, selective hydrogenation and catalytic oxidation was vsvified in a sot/a pilot plant, the total yield of glutaraldehyde was 50%. The coking was effectively controlled by optimizing the structure of depolymerization reactor. The selectivity of cyclopentene was increased by using the adjusting catalyst to avoid further hydrogenation of cyclopentene. By using new catalyt system and the outside circulation of kettle reactants to remove the reaction heat, the yield of glutaraldehyde was increased. |
