<p>A process for synthesising compounds of aluminium and alkaline earth metals containing hydride hydrogens and alkoxy radicals, of formula - xB in which 0.5? n ? 3.5; OR is an alkoxy radical derived from a primary, secondary or tertiary alcohol; R is an aliphatic, cycloaliphatic or aromatic hydrocarbon radical; M is an alkaline earth metal; R is a Lewis base; x can vary between 0 and 4; and R can also contain functional groups such as OR', SR', NR'2 wherein R' is a hydrocarbon radical. This process consists in reacting together: a) a halide of an alkaline earth metal; b) an alanate of an alkaline earth metal of formula M' AlH4 (M' = alkaline metal); c) an alcohol chosen from primary, secondary or tertiary aliphatic, cycloaliphatic or aromatic alcohols containing 1 to 20 carbon atoms. The so-obtained compounds are useful as hydrogenation agents or as drying agents for solvents.</p> |
