A Knudsen effusion and oxygen transpiration study of the vaporization of MgO indicates that gaseous MgO is of little importance in the vapor phase at about 2000°K. A D00 for gaseous MgO of about 80 kcal./mole is obtained. Knudsen experiments with MgAl2O4 support a negative heat of formatio...
Since biodiesel is commonly produced by converting vegetable oil into its methyl esters with the help of catalysis of alkali-hydroxide dissolved in methanol, it is necessary to eliminate the homogeneous catalyst from the crude biodiesel by washing with a large amount of water. With a view of stud...
