Conclusion

  1. 1.

    The condensation of formaldehyde to form carbohydrates in the presence of Ca(OH)2 and Pb(OH)2 takes place in a definite range of alkaline pH values, which is necessary for the formation of complexes of the catalysts with the carbohydrates, these complexes being the true catalytically active particles in this reaction.

     
  2. 2.

    The value of the pH of the reaction system varies in a complicated manner over the course of the reaction and is determined by the ratio between the concentrations of the reaction products and the complexes of the catalyst with formaldehyde and the carbohydrates.
