Abstract: Process comprises reacting phthalamidic acid alkali salts with hypohalite in aq. medium in presence of Br2, I2 and/or a cpd. X.NR1R2 (R1 = SO3H, SO2NH2 or sulphonate R2 = H, Cl, Br; X = Cl, Br or H; R1 and R2 may also together with N form a heterocycle having >=1 sulphonic gp, or gp. of formula -P(O)OR3 adjacent the ring N; R3 = H or alkali or R1 and R2 are together -CO.R4.CO-, R4 = alkylene, -N(R5)CON(R5)- or N(R5).C(R6)2-; R5 = H, Cl or Br; R6 = aliphatic residue). Isatoic anhydrides, which are inters. for dyes, plant protection agents and flavouring, are obtd. in good yield and purity.

Abstract: o,o'-Dithiodibenzoic acids are prepared by a process wherein a diazotized anthranilic acid or anthranilate is reacted with sulfur dioxide in the presence of an acid, water and a copper salt, and if desired in the presence of an alkali metal iodide, in a 1st stage at from 20 DEG to 50 DEG C. and then in a 2nd stage at from 80 DEG to 100 DEG C. The o,o'-dithiodibenzoic acids obtainable by the process of the invention are useful starting materials for the preparation of crop protection agents, dyes and drugs.

Abstract: 1,2-Benzisothiazolones and their alkali metal salts are prepared by reacting 2,2'-dithiodibenzamides in the presence of oxygen or oxygen donors in an aqueous alkaline medium to which a water-soluble organic solvent may be added and, if desired, freeing the benzisothiazolones from the alkali metal salts with acid.

Abstract: A process for the preparation of saccharin by reacting an aqueous hydrochloric acid solution of o-methoxycarbonylbenzenediazonium chloride with sulfur dioxide, wherein (a) the aqueous diazonium salt solution is reacted with sulfur dioxide at from 0 DEG to 100 DEG C. in the presence of a water-immiscible or only partially water-miscible inert organic solvent, (b) in order to decompose the diazonium salt, the reaction mixture is treated simultaneously or subsequently with a diazonium salt decomposition catalyst, (c) the aqueous organic reaction mixture, or the organic phase obtained after removing the aqueous phase, is treated with an oxidizing agent at from 0 DEG to 100 DEG C.

Abstract: A process for the preparation of compounds of the formula I I where R is alkyl, by sulfonation, chlorination and nitration starting from an alkylbenzene, wherein the alkylbenzene is sulfonated with from 2.5 to 3, preferably from 2.65 to 2.75, moles of concentrated sulfuric acid per mole of alkylbenzene, the reaction product is then reacted with from about 1.1 to 1.3 moles of chlorine in the absence of a catalyst, the product is subsequently nitrated with highly concentrated nitric acid at elevated temperatures and the nitro compound is isolated.
