Synthesis of charged chitosan nanoparticles as functional biolubricant

Colloids and Surfaces B: Biointerfaces, 2021
Osteoarthritis 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 and characterization of biolubricant obtained by methyl epoxidation of sunflower oil

III SEVEN INTERNATIONAL MULTIDISCIPLINARY CONGRESS, 2023
One of the issues present in the determinations of the National Solid Waste Policy concerns the disposal of vegetable oil from frying generated in homes and commercial establishments. In Brazil, it is estimated that three billion liters of edible vegetable oil are produced per year. Of this total, only 2.5% is reused for some purpose, while the rest is

Synthesis biolubricant from rubber seed oil

AIP Conference Proceedings, 2017
The 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, 2013
Abstract 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.

Chemical Modification of Dehydrated Castor Oil for Synthesis of Biolubricant

SSRN Electronic Journal, 2020
Vegetable 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

2023
Over 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.

Synthesis and characterization of neopenthyl glycol diolete as a biolubricant base

AIP Conference Proceedings, 2015
Neopenthyl 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.

Green synthesis of biolubricant base stock from canola oil

Industrial Crops and Products, 2013
Abstract 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 ...

Synthesis, Characterization, Tribological and Rheological Properties of Oleyl Oleate Based Biolubricant

Egyptian Journal of Chemistry, 2021
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.
