Synthesis of fatty acid methyl esters from pomace oil catalyzed by zinc stearate: A kinetic study of the transesterification and esterification reactions
(Multidisciplinary Digital Publishing Institute, 2019-12)
In this work, the simultaneous transesterification and esterification reactions of olive pomace oil with methanol catalyzed by zinc stearate were studied. This catalyst is a crystalline solid at room temperature, but it ...
Effect of di(2-ethyl hexyl phthalate)/epoxidized soybean oil and calcium stearate/zinc stearate ratios on the tensile properties of plasticized PVC formulations. A study for calcium stearate rich formulations
(2009)
Two series of plasticized PVC formulations were prepared, containing one of the following di (2-ethyl hexyl phthalate)/epoxidized soybean oil ratios (phr/phr): (a) 35/3, (b) 55/3, (c) 45/0 or, (d) 45/6. For each ratio, the ...

Response surface study and kinetic modelling of biodiesel synthesis catalyzed by zinc stearate
(Pergamon-Elsevier Science Ltd, 2018-12-01)
This contribution reports experimental and theoretical studies on the transesterification of soybean oil with methanol catalyzed by zinc stearate. This reaction produces fatty acid methyl esters (FAME) and glycerol, and ...
Superhydrophobic brass and bronze meshes based on electrochemical and chemical self-assembly of stearate
(Elsevier Science, 2019-01)
The preparation and characterization of superhydrophobic membranes formed on metal meshes (brass and bronze) by coating from stearic acid is presented. The membranes were prepared by two methods: electrolysis and acid ...
Thermal stability characterization of plasticized PVC compounds using calcium and zinc stearates
(2004)
Thermal stability of plasticized PVC compounds (50 phr di(2-ethyl hexyl) phthalate and 0 or 5 phr of epoxidized soybean oil) was studied. The effect of Ca/Zn stearate ratio (0.0/1.0, 0.2/0.8, 0.4/0.6, 0.6/0.4, 0.2/0.8 and ...
