    Abstract: Azo dyes of the formula in which R and R are each hydrogen, C1-C4-alkyl or C1-C4-alkoxy, R is hydrogen or C1-C8-alkyl which is optionally substituted by hydroxyl and can be interrupted by 1 to 3 oxygen atoms, R is C1-C8-alkyl which is optionally substituted by hydroxyl and can be interrupted by 1 to 3 oxygen atoms, and X is cyano or optionally substituted C1-C8-alkoxycarbonyl, with the proviso that at least one hydroxyalkyl radical is present in the molecule, mineral oils containing one or more of the novel dyes, and the use of the novel dyes for labelling mineral oils.

    Abstract: Sulphatobetaines of formula (I) are prepd. by reacting an amine-SO3 adduct of formula (II) with an alkylene carbonate of formula (III). Reaction is at 80-220 deg.C, using an inert solvent and/or an excess of (II) and/or an excess of (III) as solvent. R1, R2 = 1-22C (un)branched satd. alkyl, 5-7C cycloalkyl, phenyl, naphthyl or 7-12C aralkyl; or the R1 gps. and the N form a 5-6 member ring, opt. contg. other heteratoms and opt. with a condensed benzene ring and R2 is 1-4C alkyl; or the R1 gps., R2 and N form a 5-6 member unsatd. ring, opt. contg. other heteroatoms and opt. with a condensed benzene ring; R3 = H or 1-7C alkyl; R4 = H, 1-20C alkyl or phenyl; and R3 and R4 are interchangeable.
