Quaternaryonium salts of halides can be efficiently converted into the corresponding quaternaryonium salts of various anions [NO3–, BF4–, PF6–, CF3SO3–, CH3SO3–, ClO4–, p-CH3C6H4SO3–, CF3CO2–, 2,4-(NO2)2C6H3O–] by treating the oniumhalide with trimethyl phosphate under neat condition in the presence of an equivalent amount of conjugate acid of the desired anion.

This invention concerns a promoted catalyst system for making one or more alkanols from synthesis gas. The catalyst system contains a ruthenium compound and a halogen promoter dispersed in a low-melting tetraorganophosphonium salt. The halogen promoter is a compound capable of generating HX (where X═Cl, Br, or I) under reaction conditions. The invention also concerns a process for selectively preparing one or more alkanols from synthesis gas using the promoted catalyst system.
