“…As an important chemical raw material (Vasishtha et al, ), due to its low toxicity and high temperature resistance, sebacic acid remained the highest castor oil derivatives consumption in 2015 and held more than 20% of the global market revenue (Grand view research, ). It can be used for the manufacture of high temperature lubricating oil such as isopropyl sebacate, high quality engineering plastics such as nylon‐610 and nylon‐810, artificial perfume such as diethyl sebacate, as well as resins, fibres and cosmetics (Ito et al, ; Raouf, ; Shende et al, ; Tang et al, ; Xia et al, ).…”

Castor oil and its three derivatives including methyl ricinoleate, sodium ricinoleate and ricinoleic acid were used as the raw material for alkali fusion to prepare sebacic acid. The reaction parameters including catalyst, ratio of oleochemicals/NaOH, reaction time and reaction temperature were optimized. It was found that Pb3O4 (1%) showed the best catalytic performance, and 553 K was considered as the most suitable reaction temperature. The oleochemicals/NaOH ratios of 15:14, 15:14, 15:12 and 15:14 were determined as the optimal ratio for alkali fusion of castor oil, methyl ricinoleate, sodium ricinoleate and ricinoleic acid, respectively. In addition, the optimal reaction time of alkali fusion of castor oil was 5 hours, and that of its derivatives was 3 hours. The maximum yield in sebacic acid of 68.8%, 77.7%, 80.1%, 78.6% can be obtained by using castor oil, methyl ricinoleate, sodium ricinoleate and ricinoleic acid as the raw material, respectively. High purity of sebacic acid was confirmed by GC and melting point analysis. ICP‐OES results illustrated that the content of Pb in sebcic acid was less than 1 mg kg−1. Separating glycerol from castor oil was beneficial for alkali fusion, by which, the yield of sebacic acid was increased of approximately 10%, and the reaction time was reduced from 5 to 3 hours. This study provided guiding significance for the future industrial production of sebacic acid.

“…Sebacic acid (C 10 H 18 O 4 ) is the main product of alkali fusion. As a saturated aliphatic dicarboxylic acid containing ten carbon atoms, with the chemical similarity of saturated dibasic acid, this important chemical raw material has been widely used in producing high-temperature-resistant lubricant, high-temperature lubricating oil such as isopropyl sebacate, artificial perfume such as diethyl sebacate, high-quality engineering plastics such as nylon-610, and biodegradable polyesters for the medical industry. − …”

A green and environmentally friendly route of no thinning agent was designed to prepare sebacic acid. Sodium ricinoleate was selected as the raw material to carry out solid-phase cleavage in a tubular furnace. The reaction parameters including catalyst, ratio of sodium ricinoleate/KOH, reaction time, reaction temperature, and absolute pressure were optimized to obtain a high yield of sebacic acid. A satisfactory yield (70.2%) of sebacic acid was received in the presence of 1% catalyst (Fe 2 O 3 ) by weight (w/w), with 5:4 (w/w) ratio of sodium ricinoleate/KOH at 543 K under the absolute pressure of 0.09 MPa in 60 min. Sebacic acid was identified by gas chromatography analysis, and the purity (98.1%) of the product was further assessed by its melting point (306.3 K). Alkaline enhancement generates a better cracking effect. The yield of sebacic acid can be improved by a certain absolute pressure as a result of avoiding oxidation of sodium ricinoleate as well as reducing the residence time of hydrogen.
