Abstract

Procedure for obtaining O, N or N, N-acetals, of general formula ** (See formula) ** where y represents an integer from 1 to 5, R'means a 1-4-valent aliphatic or cycloaliphatic moiety, with a maximum of 10 carbon atoms, the carbon chain of which can be interrupted by heteroatoms, preferably oxygen or nitrogen atoms, and R represents a C1-C6-alkyl, C4-C10 cycloalkyl residue, the carbon ring of which contains, optionally, heteroatoms, preferably oxygen atoms, or a C7-C14 residue, aralkyl, and ** (See formula) ** where z represents 1 or 2, R'' means C1-C6, -alkyl, (see formula), A = C1-C6 alkyl, C7-C14-aralkyl, C4-C10-cycloalkyl residues or a group -CH2-CH2-OH and R'''means C1-C6-alkyl, C6-C14- residues. aryl, C7-C14-aralkyl, C4-C10, cycloalkyl, or a hydrogen atom, and ** (See formula) ** wherein R4 signifies a C1-C6-alkyl moiety and R'''has the indicated meaning, and ** (See formula) ** in which R and R'''have the meaning already indicated, by reaction of secondary amines and alcohols with aldehydes or secondary amines with aldehydes, characterized in that secondary amines are reacted, of general formula: ** (See formula) ** with formaldehyde and alcohols of formula R'(OH) and either aldehyde of general formula R''' -CHO with secondary amines of general formula R'''(NH-CH2-CH2-OH) z, or aldehyde of general formula R'''- CHO with secondary amines of general formula R4 -NH- CH2-CH2-NH-R4 or aldehyde of general formula R''' -CHO with secondary amines of formula ** (See formula) ** in a molecular ratio of 1: 2.
