WebNov 12, 2007 · Methanol was used in order to dissolve sodium hydroxide. Methanolysis was, also, observed to some extent in the presence of higher-levels of methanol. This interesting observation encouraged us to study and develop an efficient and practical saponification process in non-aqueous conditions that would be applied to a variety of esters (Eq. 1). WebIn the reaction, the triglycerides are readily transesterified batch wise in the presence of the catalyst at an atmospheric pressure and temperature of 60–70°C in the presence of excess methanol [150]. The main drawback with the process is the formation of soap at high free fatty acid concentrations [151].
