Abstract: NEW (B-CARBAMOYL-B-HYDROXYETHYL) - ALKYLAMMONIUM SALTS HAVING A LONG CHAIN ALKYL RADICAL AND THEIR PRODUCTION BY REACTION OF PRIMARY OR SECONDARY LONG CHAIN ALKYLAMINES WITH GLYCIDAMIDE FOLLOWED BY FURTHER REACTION OF THE RESULTANT INTERMEDIATES WITH ACIDS OR QUATERNIZING AGENTS. THESE SATLS ARE VALUABLE FAT-LIQUORING AUXILIARIES FOR LEATHER, HAVE THE ABILITY OF INCREASING THE ABSORPTIVTIY OF PAPER, ARE USEFUL AS ORE FLOTATION AGENTS, AND ARE EFFECTIVE REWETTING AGENTS FOR FIBROUS MATERIALS.

OR THE RADICAL

R3-N(-R2)-COO-

X DENOTING HALOGEN OR A CYANO, NITRO, ALKYL, ALKENYL ALKOXYL, HALOALKYL OR HALOALKENYL RADICAL (THE VARIOUS MEANINGS OF X MAY BE IDENTICAL OR DIFFERNT), M DENOTES ONE OF THE INTEGERS FROM 0 TO 4, N DENOTES ONE OF THE INTEGERS FROM 0 TO 6, R2 DENOTES HYDROGEN OR A LOWER ALKYL RADICAL OR ALKENYL RADICAL AND R3 DENOTES HYDROGEN OR THE TRICHLOROETHYLOL RADICAL

(CL3-CH(-OH)-

THE CHLORAL COMPOUNDS HAVE A GOOD HERBICIDAL ACTION. IN PARTICULAR, THEY ARE SUITABLE FOR CONTROLLING UNWANTED PLANTS BETWEEN CROP PLANTS WITHOUT DEMAGING THE LATTER. THE CHLORAL COMPOUNDS HAVE AN ESPECIALLY STRONG ACTION ON UNWATED GRASSY PLANTS.

Abstract: A process for purifying indigo comprises extracting an aqueous leuco indigo alkali metal salt solution with an inert solvent, eg toluene under oxygen-excluding conditions and conventionally regenerating the indigo by oxidation. The solution may be made by dissolving the as-synthesized indigo in water by reduction in the form of the alkali metal salt of its leuco form.
