Lanthanide dodecyl sulfates, a potent family of catalysts for the preparation of biobased epoxy thermosets.

Lanthanide dodecyl sulfates, LnDS, are remarkably effective to catalyze the reaction of diepoxides with diamines in the liquid and solid states, a key reaction in the formation of epoxy thermosets. Among all lanthanides, the lanthanum complex LaNa(DS)(HO) is the most active, allowing a decrease of 60 kJ mol of the activation energy between polyethylene imine and limonene dioxide, a biobased epoxy monomer.

Correlation between the hydrophilic character and affinity towards carbon dioxide of montmorillonite-supported polyalcohols.

Polyalcohol incorporation was found to enhance the hydrophilic character of montmorillonite and its affinity towards carbon dioxide. CO2 adsorption occurred in both dry and humid conditions, but higher amounts were retained in the presence of moisture. This suggests two adsorption pathways: 1.
