Reactions are usually slow, but might become violent if local heating accelerates their rate. the Succinic group leads Succinic acid is one of the most promising bio-derived platform chemicals because it could potentially replace the current maleic anhydride C4 platform. J. However, several significant challenges hinder the widespread adoption of bio-SA in the market. This small peak is supposed to be due to the conversion of succinic acid into succinic anhydride because the pure succinic acid also shows a bunch of endothermic peaks at the same temperature range (Fig. 3). Characterization results showed that Ni particles were highly dispersed in the catalysts so that they possessed the high density of active Ni sites, and thus the high activities for the reaction. The esterification of succinic anhydride with methanol proceeds in two steps represented by the following stoichiometric equations: 0 0 0 0 O-CH3 + HzO O-CH3 Succinic acid is a four-carbon dicarboxylic acid (butanedioic acid or amber acid, C 4 H 6 O 4; Figure 8).
