Esterification of levulinic acid over Sn(II) exchanged Keggin heteropolyacid salts: An efficient route to obtain bioaditives

Marcio Jose Da Silva et al.

Summary: This paper describes a process to convert biomass derivatives into bioadditives using solid Sn1.5PW12O40 catalysts, which exhibit high activity and selectivity for the main reaction products. The impacts of the main reaction parameters were investigated, highlighting the use of renewable raw materials and efficient, recyclable catalysts as the main positive features of this process.

Transition Metal-Substituted Potassium Silicotungstate Salts as Catalysts for Oxidation of Terpene Alcohols with Hydrogen Peroxide

Marcio Jose da Silva et al.

Summary: The catalytic activity of transition metal-substituted potassium silicotungstate salts on the oxidation reactions of terpene alcohols was investigated in this work. Among the salts studied, K5SiFeW11O39 showed the highest activity and selectivity, attributed to its highest Lewis acidity.

Monoterpenes etherification reactions with alkyl alcohols over cesium partially exchanged Keggin heteropoly salts: effects of catalyst composition

Marcio Jose da Silva et al.

Summary: The study found that phosphotungstate is the most effective Keggin heteropolyacid catalyst, and Cs2.5H0.5PW12O40 salt is the most active and selective catalyst. Investigation on the effects of reaction parameters such as temperature, time, catalyst load, etc. showed that the simultaneous presence of cesium ions and protons plays an important role in the reaction, with an optimal molar ratio of 2.5-0.5. The Cs2.5H0.5PW12O40 salt can be efficiently recovered and reused without losing catalytic activity.
