Evaluation of the performance of a castor-oil based formulation in limiting pesticide residues in strawberry crops
(Sociedade Brasileira de Química, 2014)
Study of the biodegradation of a polymer derived from castor oil by scanning electron microscopy, thermogravimetry and infrared spectroscopy
(Associação Brasileira de Polímeros, 2006-06-01)
The aim of this research is to study the biodegradation of a polyurethane derived from castor oil, which contains polyester segment in its molecular structure, thus becoming susceptible to the microorganisms attack. The ...

Preparation and physicochemical characterization of drug loaded in castor oil-based polyurethane
(Springer, 2020-02-01)
Castor oil is an environmentally friendly alternative to hydrocarbon-based feedstocks for the synthesis of polyurethanes due to its major constituent, ricinoleic acid. This work aimed to obtain and characterize castor ...
Kinetics of the Esterification of Maleic Anhydride with Castor Oil
(Plapiqui, 2011-03)
Kinetics reaction between castor oil and maleic anhydride without condensation and catalyst was studied. On the other hand, the products concentration, kinetics and thermodynamics parameters were determined using mathematical ...
Kinetics of the Transesterification of Castor Oil with Maleic Anhydride Using Conventional and Microwave Heating
(Springer, 2012-01)
The transesterification of castor oil with maleic / anhydride was studied using conventional and microwave heating. Reactions were followed by measuring the acid value and the reaction products were characterized by FTIR ...
Production of biodiesel from castor oil using sub and supercritical ethanol: Effect of sodium hydroxide on the ethyl ester production
(Elsevier Science BvAmsterdamHolanda, 2013)
Transesterification of soybean and castor oil with methanol and butanol using heterogeneous basic catalysts to obtain biodiesel
(Pergamon-Elsevier Science Ltd, 2018-09)
This paper focuses on the preparation and characterization of CaO, MgO and ZnO, both bulk and supported on γ-Al2O3 and their catalytic activity in the transesterification of soybean oil and castor oil with methanol and ...
Polyurethane elastomers-based modified castor oil and poly( -caprolactone) for surface-coating applications: Synthesis, characterization, and in vitro degradation
(Journal of Elastomers and Plastics, 2014)
Polyurethanes (Pus) were synthesized from castor oil and modified through transesterification by pentaerythritol, poly(ε-caprolactone)diol (PCL), and isophorone diisocyanate to form PU coatings. The ratio of NCO/OH groups ...
