Abstract:
3,4-Dihydro-1,2,3-oxathiazinones, a class of chemical compounds having a ring system, are obtained by converting the enolether of a Beta -ketocarboxylic acid amide-N-sulfone to the enol and treating the enol with an aqueous base. The compounds and their salts are artificial sweetening agents. All of the compounds are organic intermediates having a plurality of reactive groups.
Abstract:
The installation has a continuous conveyor belt that is borne by supporting cables and moved along guide cables from a loading station to an unloading station. The belt is guided over deflecting drums in the loading and the unloading station. A respective turning device is located downstream of the unloading station and upstream of the loading station, and fastened on supporting frames. The device turns the return strand of the belt. The guide is formed with a helically running guide track that turns the belt downstream of the unloading station and upstream of the loading station.
Abstract:
Combining non-enzymatic preservations with enzymes having an N-acetylmuramidase activity results in effective synergism, notable for the fact that foodstuffs, drugs and cosmetic products, in particular, as well as packing materials, tobacco and tobacco products can be conserved for a comparatively longer period than by means of the individual ingredients.
