Effect of Castor Oil as an Auxiliary Stabilizer in the Production of Flexible Polyurethane Foams

Researchers from Nigeria performed an experiment to castor oil polyurethaneanalyze the effect of castor oil as an auxiliary stabilizer in the production of polyurethane foams.  Castor oil was used as a substitute to silicone oil at different percentages.

The results showed that castor oil could be a best partial substitute for silicone oil at higher densities.

Tribological Properties of the Castor Oil affected by the Additive of the Ionic Liquid [HMIM]BF4

Scientists from China conducted an experiment to investigate the influence of ionic liquid [HMIM]BF4  as an additive on the tribologicaal properties of castor oil. The experiment was done by using a four-ball friction test rig.

Castor oil

The results showed that a small amount of ionic liquid can postpone the peak coefficient of friction and decrease the wear behaviour. In addition, the chemical adsorption of castor oil and ionic liquid on a steel surface is more significant than physical adsorption. Thus, the study could be of great importance to understand the potential engineering application of castor oil.

Synthesis of Bio-Castor Oil Polyurethane Flexible Foams and the Influence of Biotic Component on their Performance

Scientists from China conducted an experiment to synthesize bio-castor oil polyurethane flexible foams and study the influence of biotic component on their performance. A series of biobased polyurethane foams were synthesized bCastor oil polyurethaney substituting polyether polyol with castor oil and polyethylene glycol (PEG). The influence of castor oil component on the structure and physical properties of polyurethane foams were studied.

Results showed that the Young’s modulus and compression resilience improved with increased content of castor oil. They also exhibited lower water absorption and higher contact angle with increase in content of castor oil.

Studies on Interfacial Tension and Contact Angle of Synthesized Surfactant and Polymeric from Castor Oil for Enhanced Oil Recovery

Researchers from India performed an experiment to study interfacial tension and contact angle of synthesized surfactant and polymeric from castor oil. The polymeric surfactant was synthesized from pre-synthesized sodium methyl ester sulfonateCastor oil (surfactant) and acrylamide for application in chemical enhanced oil recovery.

The synthesized surfactant and polymeric surfactant were used to measure interfacial tension between their aqueous phase and crude oil phase. Contact angles of solid-crude oil-surfactant interface were also measured. Results showed that interfacial tension was lower which is effective for oil recovery.

Response Surface Methodology for Optimization of Bio-Lubricant Basestock Synthesis from High Free Fatty Acids Castor Oil

Scientists from India performed an experiment to optimize the synthesis of biolubricCastor oilant basestock from high free fatty acid castor oil via epoxidation reaction. Influence of various process parameters was optimized.  Central composite design (CCD) was used to evaluate the effects of process variables on maximum oxirane oxygen content (OOC).

From the response surface methodology study, it could be concluded that low FFA CO could act as a suitable feedstock for lubricant synthesis with improved physico-chemical properties.
