This paper discussed some physical and chemical properties of trihydrated MgCO3 and its hydrolytic product-basic MgCO3 is obtained from NH4HCO3 reacting with MgCl2 solution. The trihydrated MgCO3 and basic MgCO3 are examined with differentia thermal gravimetric, differential thermal, infrared spectra and X-Ray diffraction analyses. Besides, we find out that the two molecules of crystal water in MgCO3·3H2O have different bonding abilities, that the structural formulae of MgCO3·3H2O and 3MgCO3·Mg (OH)2·4H2O...

This paper has dealt with the relationship between the composition of the rare earth benzilate complexes and the conditions of their preparation. The solubilities of these complexes in organic solvents, the results obtained from the infrared, nuclear magnetic resonence, ultraviolet spectra, thermorgravimetric and differential thermal analyses have been studied and discussed. It is found that all these comlexes contain hydroxyl groups and crystal water. The number of crystal water varies with the condition of preparation. These complexes dissolve difficultly in many organic solvents. The solubility of these compounds in absolute ethyl alcohol, the association degree and the temperature of thermal dicomposition decrease with the increase of the atomic number of the rare earth elements.
