Lactic and Ricinoleic Acid Based Copolyesters Stereocomplexation
Macromolecules, 2005A systematic study of the synthesis and stereocomplexation of l-lactic acid and ricinoleic acid based copolyesters is reported. l-lactic acid and ricinoleic acid based copolyesters were synthesized by melt condensation and transesterification of high-molecular-weight poly(lactic acid) (PLA) with ricinoleic acid and repolymerization by condensation to ...

Determination of ricinoleic acid by differentiating titrations
Journal of the American Oil Chemists' Society, 1965AbstractA technique based on a method of differentiating titrations was developed for the resolution of mixtures of ricinoleic, sulfuric and ethylsulfuric acids. The total and partial acid values were determined by potentiometric titration with a glass‐calomel electrode using aqueous sodium hydroxide as titrant.

QSAR studies of antibacterial ricinoleic acid derivatives
Pharmaceutical Chemistry Journal, 2007A series of ricinoleic acid derivatives has been synthesized and tested for antibacterial activity with respect to four standard strains. Dibromoricinoleic acid (DBRA) showed high activity comparable with that of the reference drug ciprofloxacin. QSARs between various physicochemical indices and the antibacterial activity of a training set including 12

Surfactant enhanced ricinoleic acid production using Candida rugosa lipase
Bioresource Technology, 2010In this study, ricinoleic acid was produced on surfactant enhanced castor oil hydrolysis using Candida rugosa lipase. The most effective surfactant was Span 80. Employing fractional factorial design, the most suitable temperature and surfactant concentration were found to be 31 degrees C and 0.257% (w/w in buffer) respectively whereas pH, enzyme ...

Polyester polyols and polyurethanes from ricinoleic acid
Journal of Applied Polymer Science, 2008AbstractTriols of molecular weights (MWs) 1000–4000, suitable for flexible foams, were prepared by transesterification of methyl esters of ricinoleic acid with trimethylol propane. These polyols were noncrystallizing, relatively low‐viscosity liquids. They were reacted with diphenylmethane diisocyanate (MDI) to obtain elastomers having glass transition
