Recently, the pilot research project of hydrogenation of dimethyl sebacate to decandiol undertaken by Sinopec Nanjing Chemical Research Institute Co.
, Ltd.
passed the evaluation
of scientific research results organized by the Ministry of Science and Technology of Sinopec.
The project completed the pilot research package of hydrogenation of dimethyl sebacate to decanediol of 200 tons/year, and prepared the feasibility study report of the pilot study
.
The project developed a continuous hydrogenation process and special catalysts, and built a pilot plant
with a scale of 200 tons/year.
The results of the pilot study showed that the conversion rate of dimethyl sebacate was not less than 99.
5%, the selection rate of decylene glycol was not less than 97%, and the purity of the product was not less than 99.
2%.
In addition, the project has applied for 6 Chinese invention patents, and 4 have been authorized
.
As a fine chemical raw material, 1,10-decanediol can produce a series of new fine chemical products, which are used in the fields of flavor additives, pharmaceutical intermediates and high-performance materials, and have broad
market application prospects.
