    Abstract: Prodn. of N-substd. morpholinium salts of formula (I) comprises cyclisation of bis (2-hydroxyalkyl)ammonium salts of formula (II) by dehydration at pH 2-6. R1HN+(CHR2.CHR2.OH)2 n Xn- (II) In the formulae, R1 and R2 are each aliphatic group, R2 can also be H and R1 can also be cycloaliphatic, araliphatic or aromatic group; X is an acid anion; n = 1 or 2. Free morpholine bases corresp. to (I) are useful for making surfactants, anticorrosion agents and plant-protection agents. (I) are prepd. without use of large amts. of acid, special solvents, or catalysts from readily available starting materials. Yields and purity of (I) are better than in known processes, esp. impurities which can damage plants are not produced.
