摘要

"Aqueous solution of formaldeu00ecdo, processes to prepare the same and reaction products, and the use of an aqueous solution of formaldeu00ecdo".The invention relates to an aqueous solution of formaldehyde and formaldehyde in monomeric form of formaldehyde.Methylene glycol and polyoxymethylene glycols in a total concentration x 242 65% by weight, characterized by the fact that the molar mass average sym of polyoxymethylene glycols.As a function of the concentration of formaldehyde.Is equal to or less than the values given in equation I: in which: - 242 is the molar mass average; - x is the total concentration of formaldehyde in monomeric form of formaldehyde.Methylene glycol and polyoxymethylene glycols in% by weight (total concentration of formaldehyde).
