    Abstract: The invention relates to compounds of the general formula (I) in which A is a dye radical, optionally the radicals Y independently of one another are oxygen, sulphur, R -N or a direct bond, n is the number 1 or 2, the radicals R independently of one another are hydrogen or optionally substituted C1- to C4- alkyl and Z is a bridging member. The compounds according to the invention are highly suitable for dyeing textile material which contains hydroxyl groups.

    Abstract: The invention relates to compounds of the general formula I in which R is hydrogen or a (cyclo)aliphatic, araliphatic, aromatic or heteroaromatic radical which is optionally substituted by fluorine, chlorine, bromine, methoxy, ethoxy, nitro, C1- to C4-alkyl, methylsulphonyl, ethylsulphonyl, cyano or hydroxysulphonyl. The compounds according to the invention are suitable after linkage to dyestuffs as reactive compounds.

    Abstract: Methyl m-nitrobenzoate is prepared by a process in which an isomer mixture is treated with from 10 to 1000% by weight of water in the presence of from 0.05 to 20% by weight of an emulsifier, the percentages being based on the weight of the isomer mixture, (a) in a first stage at from 55 DEG to 100 DEG C. and a pH from 2 to 8 and then (b) in a second stage at from 10 DEG to 40 DEG C. and a pH of not less than 9. The methyl m-nitrobenzoate obtainable by the process of the invention is a useful starting material for the preparation of dyes and crop protection agents.

    Abstract: Fatty acid esters of ascorbic acid are prepared by a process in which a homogeneous mixture of (a) ascorbic acid, (c) concentrated sulfuric acid having a concentration of not less than 96% and (c) a methyl or ethyl ester of a fatty acid of 12 to 18 carbon atoms is reacted at from 20 DEG to 50 DEG C. Using the novel process, the fatty acid esters of ascorbic acid, in particular ascorbyl palmitate, which are very desirable antioxidants are obtained by a procedure which is technically simpler and hence cheaper than the conventional processes, but in equally good yields.
