Abstract: N-acyl urethanes useful as cocatalysts for lactam polymerization are obtained by reacting organic acid amides, such as carboxylic acid amides, carbamic acid esters or ureas, with trihalogenoacetic acid esters, whereby trihalogeno-methane is split off. The process is preferably catalyzed by amines, especially by tertiary or sterically hindered amines.

Abstract: POLY-B-AMIDES ARE PREPARED IN A TWO-PAHSE DISPERSION BY POLYMERIZING B-LACTAMS WHICH ARE UNSUBSTITUTED AT THE NITROGEN ATOM. ONE OF THE PAHSES CONSISTS OF AN ALIPHATIC OR A CYCLOALIPHATIC HYDROCARBON AND THE OTHER OF A SOLUTION OF THE LACTAM IN A HIGHLY POLAR SOLVENT. THE PREPARATION IS CARRIED OUT IN THE PRESENCE OF CATALYSTS, PROMOTERS AND EMULSIFIERS, THE POLY-B-AMIDES PRODUCED ARE SUITABLE FOR THE MANUFACTURE OF MOLDED ARTICLES, FILMS AND FILAMENTS.

Abstract: IN WHICH R1 and R2 stand for lower alkyl radicals, R3 represents a hydrogen atom or a methyl group, X is an oxygen or a sulfur atom, Y is an oxygen atom or a group of the formula -NR-, wherein R stands for a hydrogen atom or a lower alkyl group, and n represents 1, 2 or 3. The polymers and, in particular, the filaments, fibers or sheets manufactured on the basis of these polymers containing phosphorus are marked by a reduced inflammability and and improved capability of being dyed.

Phosphorus-containing homopolymers and copolymers are disclosed which comprise recurring units of the formula

Abstract: 6-Methyl-3,4-dihydro-1,2,3-oxathiazin-4-one 2,2-dioxide and its non-toxic salts are prepared by reacting acetoacetamide with an S-O compound of the formula I FSO2Y (I) wherein Y=F, Cl, -OSO2F or -OSO2Cl, preferably only F, in the presence of bases. The non-toxic salts-especially the potassium salt-are valuable synthetic sweeteners.

Abstract: of the disclosure: The invention relates to new 2-ketosulfonamides of the formula and to a process for their preparation, wherein the 3-amino-2-sulfamoylalk-2-enoic acid esters of the formula obtained by reacting 3-aminoalk-2-enoic acid esters of the formula with amidosulfonyl chlorides of the formula X-S02-NH-R2, are subjected to hydrolysis and decarboxylation. The invention also relates to the 3-amino 2-sulfamoylalk-2-enoic acid esters which can be isolated as intermediates. The 2-ketosulfonamides of the formula (I) are precursors for new plant-protection agents and pharmaceuticals. They are also analogs of acylacetamides, which in turn are useful as coupling components for azo dyes and pigments.
