Kinetic analysis of the conversion of aqueous erythritol solution on Ir/ReOx/TiO2 in a batch slurry reactor was written by Virgilio, Emanuel M.;Sad, Maria E.;Padro, Cristina L.. And the article was included in Applied Catalysis, A: General in 2022.Name: 1,2-Propanediol This article mentions the following:
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, 1,2-Propanediol (cas: 57-55-6Name: 1,2-Propanediol).
1,2-Propanediol (cas: 57-55-6) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Name: 1,2-Propanediol
