ABSTRACT:
The instant invention relates to an improved process for the production of formose from formaldehyde. The improvement resides in using relatively small quanities of basic lead compounds as catalysts for the condensation reaction of the formaldehyde and, at the same time, for controlling the pH-value. By following this technique, organic or inorganic bases which, hitherto, have normally been used for this purpose are no longer needed.
