Heterocyclic compounds containing a hetero-ring with eight ring members, namely N,N''-substituted 2,5-dioxa-3,7-diazacyclooctanes are provided. These compounds are manufactured by eliminating water from the N,N-dimethylol compounds or the mixtures for the formation of these N,N-dimethylol compounds from formaldehyde and the corresponding amides or carbamic acid esters. The heterocyclic compounds are suitable as finishing agents for cellulose-containing materials, e.g., for creaseproofing, softening, hydrophobizing or oleophobizing textiles. Furthermore they may be useful as flameproofing or antimicrobical agents, or as intermediates in the manufacture of various products. |
