Abstract: Aqueous mercerizing solutions containing alkali metal hydroxide and 0.1 to 5 g/l of a phosphonic acid derivative of the formula 2/6 IN WHICH R is aliphatic hydrocarbon radical and X and Y each is hydrogen, an alkali metal ion or a lower aliphatic radical, and the use of these solutions in a process for mercerizing cellulose fibrous material..

Abstract: Process for the preparation of 4,4'-dinitrodiphenylamine which comprises reacting 1 mole of 4-halonitrobenzene with about 1 to about 3 moles of an alkali metal cyanate in the presence of about 0.5 to about 5 moles of water in dimethylsulfoxide at temperatures of about 150 DEG to about 170 DEG C.

Abstract: A process for the preparation of 3-(acyl)amino-4-alkoxy-phenyl- beta -hydroxyethyl-sulfone (sulfates) of the formula (1) (1) in which R1 is alkyl having 1-4 carbon atoms and R2 is hydrogen or one of the groupings +TR with the proviso that n=1 if R2=H and n=0 if R2=acyl, by converting 2-alkoxyacylanilines of the formula (2) (2) in which R1 and R2 have the meanings given, in a known manner to the corresponding sulfochlorides substituted in the p-position relative to the alkoxy group, reducing the sulfochlorides with an alkali metal sulfite or ammonium sulfite in an aqueous medium at pH 7.0-8.5 and at -5 to +40 DEG C. to give the corresponding sulfinates, alkoxylating the latter with ethylene oxide in an aqueous medium at pH 6.0-8.5 and 40 DEG -80 DEG C. to give the 3-acylamino-4-alkoxyphenyl- beta -hydroxyethyl-sulfones of the formula (1) (with R2=acyl and n=0) and, if appropriate, esterifying the latter, with deacylation, with concentrated sulfuric acid at 70 DEG -150 DEG C. to give the compounds of the said formula (1) (with R2H and n=1).

Abstract: Peracylated aliphatic polyamines are useful as activators for inorganic peroxo compounds, i.e., they set free the available oxygen of the peroxo compounds in aqueous solutions at temperatures below 80 DEG C and are thus useful as additives to detergents especially inasmuch as they are compatible with usual detergent brighteners.
