Sulfonated porous carbon catalyzed esterification of free fatty acids
The esterification of free fatty acids (FFA) with methanol is studied using Sulfonated Porous Carbon (SPC) as catalyst. In compare to the amorphous sugar catalyst and protonated Nafion, the proposed catalyst shows stability and high efficient performance in biodiesel production. The highest initial rate of oleic acid conversion is obtained at catalyst loading of 1 mmol H+ and mole ra...

متن کاملHigh Free Fatty Acids
Biodiesel is an alternative fuel for diesel engines consisting of the alkyl monoesters of fatty acids from vegetable oils or animal fats. Most of the biodiesel that is currently made uses soybean oil, methanol, and an alkaline catalyst. The high value of soybean oil as a food product makes production of a cost–effective fuel very challenging. However, there are large amounts of low–cost oils an...
متن کاملTitration of free fatty acids
Dole’s titrimetric method for determination of the free fatty acide of plasma has been modified to improve ita specificity. The fatty acid solution which is to be titrated ie first washed with 0.06 per cent H,SO, and thus freed of lactic acid and of an acetone-insoluble material which interferes. With this change, the Dole procedure yields results which agree well with those of Gordon’s me...
متن کاملMyocytes by Free Fatty Acids
Using rat ventricular cells, we studied the actions of free fatty acids and their ability to modulate the ATP-sensitive K' channel and to activate a new type of ATP-insensitive K' channel previously identified in rat atrial cells. Perfusion of the cytoplasmic face of the membrane with unsaturated fatty acids (10-50 ,M) such as arachidonic, linoleic, and eicosatrienoic acids inhibited the ATP-se...
