Abstract
A process for alkoxylation of a di, tri or polyalcohol, being solid at applied reaction temperature, in the presence of a catalytically effective amount of at least one alkoxylation catalyst is disclosed. The process is a solvent free process and comprises the steps of i) under effective stirring submitting at least one said di, tri or polyalcohol to reaction with at least one alkylene oxide, said di, tri or polyalcohol being coated with a catalytically effective amount of said at least one alkoxylation catalyst, and ii) under effective stirring charging to in step (i) obtained product and submitting to reaction further amounts of at least one said di, tri or polyalcohol and at least one alkylene oxide, and optionally iii) under effective stirring submitting in step (ii) obtained product to reaction with a further amount of at least one alkylene oxide and/or at least one di, tri or polyalcohol.
