description The invention relates to a process for the separation of colloidal barium phosphate or colloidal barium sodium phosphate, used as a heterogeneous catalyst in the alkoxylation of an active hydrogen containing organic compound, from the alkoxylated product, which comprises contacting the alkoxylated product with an amount of water sufficient to break the colloidal state of the barium phosphate or barium sodium phosphate, and collecting the phosphate.
