Experimental Conditions
The experiments were designed to study the feasibility of 3 mixtures of fresh non-refined vegetable oil and used frying oil as feedstock in the alkali-catalyzed methanolysis and the effect of the used frying oil content in oil
feedstock on the reaction.
For the latter purpose,the methanolysis of each fresh vegetable oil and used frying oil was also conducted to compare with the mixed oil feedstocks.
In this study,potassium hydroxide (KOH) was used as a catalyst for all experiments and the other reaction conditions are shown in Table
