The protonation equilibria of 1,2-benzisothiazoles, involving substituents at position 3, or the ring nitrogen at position 2, have been investigated by potentiometric and/or spectrophotometric methods.The values of the protonation constants (log Kobs) have been compared with values calculated according to the linear relationships of Barlin and Perrin.For compounds with substituents at position 3, the protonation constants have been determined potentiometrically.The presence of the benzisothiazole moiety induces an increase of base strength, with respect to that expected from the calculated substituent effects according to Barlin and Perrin.The protonation constants of the heterocyclic nitrogen at position 2 have been determined spectroscopically in very acidic solutions.The comparison of the values observed with those calculated following Barlin and Perrin for substituted isoquinoline shows that the ring nitrogen is less basic than expected.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.23031-78-9, Name is Benzo[d]isothiazol-3-amine, molecular formula is C7H6N2S. In a Patent£¬once mentioned of 23031-78-9, SDS of cas: 23031-78-9

The dyes according to the invention consist of a chromophore and a radical which, on heating, forms an isocyanate or isothiocyanate group. The latter reacts with a suitable group in the environment. Dyeings of excellent thermomigration fastness are obtained. The disclosed dyes are of the formulae STR1 where F is the radical of an azo, anthraquinone or tricyanovinyl dye which is free of water-solubilizing groups, B and B’ are each independently of the other a direct bond or a bridge member, selected from the group consisting of a straight-chain or branched alkylene group having 2 to 8 C atoms or one of the following groups STR2 where R is hydrogen or C1 -C6 alkyl, n is an integer from 1 to 8 and m is an integer from 2 to 4, Z is O or S, V is a group which at a temperature between 180 and 240 C. is eliminated as a radical HV, and V’ is a direct bond which is cleaved at a temperature between 180 and 240 C. or is a group which at such temperature turns, by ring opening and cleavage of the bond V’-C, into a group V’H, with the provisos that in the azo dyes the diazo component is not aminobenzisothiazole and the coupling component is not N-(beta-phenylureidoethyl)-1-naphthylamine when the diazo component is 2,4-dinitro-6-bromoaniline.
