  • Patent number: 4226810
    Abstract: A chemical method for splitting the pyran ring of compounds such as 2,6,6-trimethyl-5,6-dihydro-4H-pyran is disclosed which consists in reacting the 4H-pyran derivatives concerned with water and a halogen-containing or halogen-donating catalyst at a comparatively low temperature, i.e. from 50.degree. C. to 130.degree. C. Interesting results are obtained and a selection field is afforded as regards the products of the pyran-ring cleavage.

  • Patent number: 4219508
    Abstract: This invention relates to an improved process for the preparation of a mixture of various low molecular weight hydroxyaldehydes, hydroxyketones and polyhydric alcohols by the condensation of formaldehyde with itself. The essential feature of the improvement is that unpurified synthesis gases of the kind obtained from the large scale industrial production of formaldehyde can be used directly as the source of formaldehyde.
