Clean synthesis of biolubricants for low temperature applications using heterogeneous catalysts

Production of environmentally adapted lubricant basestock from jatropha curcas specie seed oil

“…According to Ghazi et al [11] and Rao et al [49], VI of 180 for Jatropha curcas-derived TMP esters and 162-172 for polyol esters of 10-undecenoic acid were obtained. Furthermore, Å kerman et al [52] reported that TMP esters of C 5 -C 18 fatty acids had VI of 80-208. When compared with previous results, JBL had shown a relatively favourable VI.…”

Bio-lubricants Derived from Waste Cooking Oil with Improved Oxidation Stability and Low-temperature Properties

“…As shown in Table 1, both WCO PP 2 and CP 4 and SBO PP 8 and CP 0 present a pour point above 10 , which is much higher than their mineral oil counterpart. This can be explained that triglycerides based oils WCO and SBO have a tendency to form macro crystalline structures at low temperature through uniform stacking of the bend triglyceride backbone and such macro crystals limit the easy flow of the fluid due to loss of kinetic energy of individual molecules during self-stacking 9,12,14 . Transforming glycerol group in vegetable oils to other branching alkyl chains would disrupt this stacking process and improve the low-temperature properties of WCO.…”

“…Gryglewicz and Akermana developed vegetable oil based trimethylolpropane TMP ester from vegetable oils methyl ester through transesterification 13 . Transesterification eliminates the β-hydrogen atom of the vegetable oil substrate, thus improving the oxidative and thermal sta-bility of the bio-lubricant base-stock 13,14 . Honary et al systematically investigated genetically modified high oleic soybean oil based lubricant and developed dozens of biolubricants 15 17 .…”

Oleochemical Industry Future through Biotechnology

“…Production of one of the most important lubricants which is trimethylolpropane trioleate on industrial scale was achieved by reaction of trimethylolpropane with free fatty acids or esters catalyzed by a homogeneous or heterogeneous chemical catalyst such as acidic resins, acid oxides, and organic ion exchange resins 42 46 trimethylolpropane trioleate was produced in Akerman and Gaber research 42 , using three different catalysts, included two heterogeneous acidic catalysts which are silica-sulphuric acid .…”
