Under the conditions of this study, the rate constants ([k.sub.obs]) depended on the total concentrations of the phosphate and acetate buffers, which indicated that the components of the buffers catalyzed the degradation of EP (general acid-base catalysis).
Since in the reaction solutions of EP in HCl and borate buffer general acid-base catalysis was not observed, in that pH range, the values of [k.sub.obs] = [k.sub.pH].

The biodiesel was synthesized from the bleached oil under acidic, basic and two step acid-base catalysis using methyl alcohol for transesterification process.
Therefore, the mechanism of catalysis is a concerted mechanism (acid-base catalysis) as illustrated in Figure 1:
