Abstract
Hydrogen cyanide and acetic acid are obtained by decomposing oximino-acetone in solution or suspension in a liquid at a temperature within the range from 20-300 DEG C., preferably in the presence of a catalyst. Neutral or acid catalysts specified include oxides or mixed oxides of elements of Groups Ia, IIa-IIIa of the Periodic Table, alkali metal or alkaline earth metal hydrogen sulphates, metal oxides of Groups IV to VI of the Periodic Table, silicates and mixed silicates of elements of Groups Ia, IIa and IIIa, kaolinite, montmorillonite, zeolite and ion exchange resins splitting off water. They may be supported on carriers such as silica gel or pumice. Basic catalysts include inorganic compounds such as sodium carbonate, organic derivatives of NH3, PH3; AsH3, SbH3\t and BiH3, and cyclic tertiary amines such as quinoline, pyridine and their alkyl substitution derivatives of low molecular weight. A list of suitable solvents is also included. The process may also be carried out in the presence of dehydrating agents such as carboxylic acid anhydrides, used in stoichiometric amounts based on the oximinoacetone: in these circumstances the decomposition may be carried out in the presence of at least one mol. of water per mol. of oximino-acetone. The process may be carried out by dissolving the oximino-acetone in a selected solvent, adding the catalyst and heating to reaction temperature, the products being separated by distillation.ALSO:Hydrogen cyanide and acetic acid are obtained by decomposing oximino-acetone in solution or suspension in a liquid at a temperature within the range from 20-300 DEG C., preferably in the presence of a catalyst.
