Evaluation of KHSO4 as a recyclable catalyst in the production of dehydrated castor oil to be applied in alkyd resins
(Elsevier, 2021-12)
Due to its lower solubility, this work proposes the use of KHSO4 as a re-usable heterogeneous catalyst in the dehydration of castor oil. Refined and degummed castor oil were considered to determine the effect of the ...
Efficiency of castor oil–based polyurethane foams for oil sorption S10 and S500: Influence of porous size and statistical analysis
(2021-01-01)
This study evaluates the efficiency of castor oil–based polyurethane foams for oil sorption S10 and S500, focusing on the influence of the pores’ size. Different foams were produced by varying the polyol: isocyanate ratio ...
Castor oil-based polyurethanes containing cellulose nanocrystals
(Wiley, 2011-06-23)
Partially foamed and nanocellulose-reinforced polyurethanes (PU) based on castor oil (CO) were prepared and their different properties were measured and related to their structures. A castor oil-based polyol (COPO) was ...
Comparison between polyurethanes containing castor oil (Soft Segment) and cancellous bone autograft in the treatment of segmental bone defect induced in rabbits
(2007-01-01)
The aim of this study is to compare polyurethanes containing castor oil (soft segment) in granular form compared to cancellous bone autograft applied to a segmental bone defect. Norfolk adult female rabbits - approximately ...

Interesterification and blending with Sacha Inchi oil as strategies to improve the drying properties of Castor Oil
(Elsevier Science SA, 2021-10)
Because castor oil is a non-drying oil, interesterification and physical blend of castor oil with sacha inchi oil were compared as methods to produce drying oils that could be used for the synthesis of alkyd resins. No ...
