Popis:	Liquid-phase cross-aldol condensation of acetaldehyde and formaldehyde in the presence of salts of various saturated and unsaturated linear amines, aromatic amines, diamines, and nitrogen bases, as well as in the presence of substituted piperazines, linear and cyclic amino acids and their derivatives, and nitrogen-containing ionic liquids, was studied. The cross-condensation products were formed in considerable amounts when amine hydrochlorides, N-benzoyl amino acids, and amino acid esters were used as catalyst. The formation of cross-condensation products is favored by increased basicity of the amino nitrogen atom in the salt and of the solvent.
