Synthesis of charged chitosan nanoparticles as functional biolubricant
Colloids and Surfaces B: Biointerfaces, 2021Osteoarthritis has been a major disease in recent years, which is mainly related to the breakdown of the lubrication function of the cartilage sliding interface, along with the inflammation of the joint capsule. In this paper, one kind of novel biomimetic nanoparticles (NPs) lubricant, named CS-PS, is synthesized through chemically grafting hydrophilic

Synthesis biolubricant from rubber seed oil
AIP Conference Proceedings, 2017The objective was biolubricant preparation from rubber seed oil (RSO) using polymerization reactor with/without catalyst in batch reactor. Before become reactant in polymerization reaction, a non-edible rubber seed oil was converted into methyl ester by esterification/tranesterification reaction with methanol and acid/base catalyst.

Synthesis of biolubricants using sulfated zirconia catalysts
Applied Catalysis A: General, 2013Abstract Synthesis of biomass-derived lubricants via esterification, transesterification, and simultaneous reactions of both was studied by using sulfated zirconia catalysts. Soybean oil or free fatty acids derived from soybean oil were used as a biomass-derived resource for the synthesis of biolubricants.

Oleyl oleate (liquid wax ester); is a principal component of sperm whale bubbler oil has an important industrial application such as cosmetic, pharmaceutical and biolubricant. In this work, synthesis of oleyl oleate was carried out through esterification between oleoyl alcohol and oleic acid using acidic heterogeneous catalyst, sodium hydrogen sulfate.

Chemical Modification of Dehydrated Castor Oil for Synthesis of Biolubricant
SSRN Electronic Journal, 2020Vegetable oils have been used as the potential feedstock for the synthesis of biolubricants. This paper focuses on the chemical modification of dehydrated castor oil (DCO). Biolubricant is synthesized via epoxidation of a blend of dehydrated castor oil with waste cooking oil (analyzed by GC-MS), prepared by reaction of oil with peroxyformic acid (H2O2 ...

Diesel biolubricants - synthesis and characterisation
2023Over the past decade, regulations have been changed to reduce the environmental impact of diesel fuel reducing the content of sulphur and aromatics. This has resulted in a deterioration of low-temperature properties and lubricity. Also more attention has been given to renewability of the products to lessen the impact on the environment.

Green synthesis of biolubricant base stock from canola oil
Industrial Crops and Products, 2013Abstract A green process for the preparation of biolubricant base stock from canola oil was developed. Three branched chain products were synthesized from commercially available canola oil. This process involves two steps, first, the preparation of epoxidized canola oil by using amberlite IR 120 catalyst followed by ring opening reaction with ...

Biolubricant from spent bleaching earth oil through propylene glycol ester synthesis
AIP Conference Proceedings, 2020An ester type biolubricant, propylene glycol ester, has been synthesized from spent bleaching earth oil (SBEO). First, SBEO was pretreated to remove coloring materials via adsorption using activated carbon, to reduce FFA (free fatty acid) via esterification using acid catalyst, to separate glycerol via transesterification using methanol, and to produce

Synthesis and characterization of neopenthyl glycol diolete as a biolubricant base
AIP Conference Proceedings, 2015Neopenthyl glycol is a polyol that is potential to be a good base for biolubricant via esterification process with oleic acid. In this study, esterification reaction between NPG and oleic acid has been carried out in the presence of 2% w/w sulphuric acid (based on weight of FA) as a catalyst to produce NPG dioleate.
