Hydration of Portland cement with red mud as mineral addition

Journal of Thermal Analysis and Calorimetry - The use of red mud from Bayer process in association with Portland cement has been shown to be promising because of its good performance on the...     

Montmorillonite clay-catalyzed cyclotrimerization and oxidation of aliphatic aldehydes

A temperature-dependent equilibrium is observed for the cyclotrimerization of aliphatic aldehydes in the presence of Montmorillonite K10 clay, while aerobic oxidation of aliphatic aldehydes to the corresponding carboxylic acids is favored at room temperature in the presence of Montmorillonite KSF clay.     

Montmorillonite clay-catalyzed hetero-Diels-Alder reaction of 2,3-dimethyl-1,3-butadiene with benzaldehydes

Montmorillonite K10 clay was found to catalyze the hetero-Diels-Alder reaction of 2,3-dimethyl-1,3-butadiene with o-anisaldehyde and other benzaldehyde derivatives; a transition state involving chelation of the clay’s metal ions with the dienophile’s heteroatoms is proposed.
