  • Method of manufacturing propynol
    Patent number: 4847440
    Abstract: A process for manufacturing propynol from formaldehyde and acetylene is disclosed. In this process the acetylene is first dissolved in a dimethoxymethane solvent under strong cooling and at slight gauge pressure. The cool acetylene-containing solution is then fed to a reactor charged with formaldehyde and a catalyst.

  • Distillation of butinediol-1,4
    Patent number: 4373999
    Abstract: A process permitting hazard free purification by distillation of compounds which are distillable per se but which present the risk of explosive decomposition under the effect of elevated temperatures. A desensitizing substance is added to the compounds to be distilled.Aliphatic alcohols for instance are suitable additives for alkinols.Examples are provided for the distillation of butinediol-1,4 together with the additive glycerin.
