Abstract
A process for the preparation of alpha-amino acids by converting an aldehyde by means of ammonia and a cyanide in a single step to the corresponding alpha-amino nitrile, and subsequently hydrolyzing the formed nitrile, characterized in that the conversion to alpha-amino nitrile is carried in a reaction medium in which, together with the components necessary for the reaction, have been dissolved, for each mole of aldehyde to be converted, at least 0.5 mole of a compound, which increases the solubility of the ammonia in the medium of reaction, or a mixture of said compounds, and the ammonia content in the reaction medium is taken at least equal to the saturation value that can be reached if together with the components necessary for the reaction, have been dissolved per mole of aldehyde to convert, 0.5 moles of said class of compounds.
