Researchers from China performed an experiment to synthesize and characterize waterborne nitrocellulose dispersion that was modified with castor oil. Castor oil modified waterborne nitrocellulose dispersion (CWNC) was castor oilsynthesized by self-emulsification and reaction among isophorone diisocyanate (IPDI) trimer, dimethylol propionic acid (DMPA), nitrocellulose (NC) and castor oil.

The characterization of CWNC was carried out with FTIR and thermal gravity analysis (TGA). TGA results showed that CWNC film had better thermal resistance.

Researchers from Malaysia performed an experiment to analyse the efficiencycastor oil biodiesel of biodiesel conversion from crude castor oil to castor oil biodiesel.  Acid-base catalysed transesterification reaction was carried out under different reaction conditions to obtain high yield of castor biodiesel.

Diesel engine performance and emission tests with different castor biodiesel blends showed that B20 blend of castor biodiesel had same engine power output as other mineral diesel with lower average percentage of change in CO and HC emissions. Thus, B20 blend of castor biodiesel could be a suitable alternative to diesel.

Scientists performed an experiment to analyze the effect of catalysis pyrolysis ofCastor seeds castor seed on the yield of oil. Catalytic pyrolysis was carried out at 400°C for different ratios of catalyst to biomass using zeolite as catalyst.

Results showed that compared to thermal pyrolysis of castor seed, catalytic pyrolysis decreased the yield of oil and that the bio oil contained compounds with carbon chain length in the range of C4-C24 that is similar to most of the fuels used.

Researchers from China performed an experiment to prepare a novel zwitterionic surfactant from castor oil. The novel zwitterionic surfactant was prepared uCastor oilsing a high yield route and its performance for oil recovery was analyzed.

Experimental results showed that the biobased surfactant exhibited strong electrolyte tolerance, temperature resistance, and thermo stability, better wetting and foaming performance, which implies that biobased surfactants could be of great potential to replace traditional petroleum based surfactants.
