Abstract: Monoalkylene glycol monoether production involves reacting an alcohol with an alkylene oxide in presence of a heterogeneous catalyst in a liquid phase. The liquid phase is in the form of a catalytically active agent composition. The monoalkylene glycol monoether having general formulae (I,II), are new. The alcohol has general formula (III), the alkylene oxide has general formula (IV), and the catalytically active agent has general formula (VI).
