Preparation of Metallic Chlorides

A facile preparation of imidazolinium chlorides.

A process for the preparation of symmetric and unsymmetric imidazolinium chlorides that involves reaction of a formamidine with dichloroethane and a base (a) is described. This method makes it possible to obtain numerous imidazolinium chlorides under solvent-free reaction conditions and in excellent yields with purification by simple filtration. Alternatively, symmetric imidazolinium chlorides ...

A Note on the Preparation of Small Quantities of Labeled Fatty Acid Chlorides.

Preparation of polyaluminum chlorides containing nano-Al13 from Egyptian kaolin and application in water treatment

In this study, a novel approach to metakaolin dealumination to produce aluminum chloride from Egyptian kaolin has been described and the prepared aluminum chloride can be used to produce polyaluminum chlorides (PACs) with various basicities (B = OH/Al values). The prepared PACs which contain Al13 ([AlO4Al12(OH)24(H2O)12] 7+ ) was investigated using XRD and colorimetric method . In XRD spectra, ...

exploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination

the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
