The influence of temperature, H2 pressure and erythritol concentration on the hydrogenolysis of erythritol was studied using Ir/ReOx/TiO2. Under the conditions used here, four reaction routes coexist: isomerization, dehydration, C-O and C-C hydrogenolysis. The initial rates as well as reaction orders and activation energy were estimated for each pathway. The variation of the hydrogen pressure produced slight changes in the isomerization, dehydration, and C-C hydrogenolysis routes, whereas C-O hydrogenolysis showed order 1 with respect to this reagent. The change in erythritol concentration affected more the dehydration, resulting in a reaction order for this reactant close to 1, while for the other routes the order was close to 0.5. Regarding the influence of the temperature, dehydration of erythritol showed the highest activation energy (212.1 kJ mol-1) and the isomerization the lowest (20.0 kJ mol-1). Furthermore, it was found that the ruptures of C-C bonds require higher energy than C-O bonds break. In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Application In Synthesis of (2R,3S)-rel-Butane-1,2,3,4-tetraol).
(2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Application In Synthesis of (2R,3S)-rel-Butane-1,2,3,4-tetraol
