Tin-Catalyzed Esterification and Transesterification .

Despite of high molar ratio of ethyl alcohol : oleic acid (120 : 1), the reaction without catalyst reached only a poor conversion (ca. 10%) after 12 hours monitoring the reaction.Contrarily, using a Lewis acid catalyst (SnCl 2 ·2H 2 O), a conversion of 87% was achieved at the same reaction time. Probably the catalyst Sn (II) activates the carbonyl group of the fatty acid, favoring his attack .

Methods of Stopping Kinetic Transesterification Reactions

On the other hand, Table 2 reveals that reaction time (Sample), concentration of quenching reagent (Column) and interaction among them have very high significant effects on viscosity. There is a possibility that excess sulphuric acid catalyses the esterification reaction with the free fatty acids and glycerols to produce more ester. 4. Conclusion

Chemical reactors - Essential Chemical Industry

It is important that the reactor can operate for several months without a shutdown. The residence time in the reactor is controlled by the feed rate of reactants to the reactor. For example, if a reactor has a volume of 20 m 3 and the feed rate of reactants is 40 m 3 h-1 the residence time is 20 m 3 /40 m 3 h-1 = 0.5 h. It is simple to control .

Catalysts | Gelest, Inc.

Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant.
