The mixture of oleic acid,water,pelargonic acid and acetic acid was treated with ozone at 0～15℃ before the reaction was fully carried out.

Pelargonic acid has a obvious antifeedant action to the imago of Pissodes punctatus Langor et Zhang.

Four carboxylic acids, nonanoic acid, 10-undecenoic acid, oleic add, z-15-tetracosenoic acid, were decarboxylated to 1-alkenes by catalyst (ph3P)2PdC12 effectively.

Improved synthesis process for azelaic acid with ionic liquid as a basic reaction system;

Study on the process for separation and purification of high purity azelaic acid;

Production of azelaic acid by the compound solvent-ozonization-catalytic oxidation process from oleic acid;

Calcium pimelate, calcium azelate and zinc azelate are prepared by alkali neutralization process, and calcium dimer are prepared using double decomposition reaction, the effect of binary carboxylate heat stabilizer on PVC thermal stability is studied adopting Congo red method and toast with heat method.
