Abstract
Compounds of the general formula <FORM:0692413/IV (b)/1> where Ar is an ortho arylene radical, R is an alkylene group and n is an integer, for use as pickling inhibitors, are prepared by introducing into 2-mercaptoarylenethiazoles one or more hydroxyalkyl radicals. The former may be 2-mercaptobenzothiazole, 2 - mercaptonaphthothiazole, 2 - mercapto - 4 - phenylbenzothiazole, 2 - mercaptochlorobenzothiazole or 2 - mercaptotolylthiazole and condensation may be effected with ethylene oxide, propylene oxide, glycide, epichlorhydrin, glycol, glycerine or polyglyamine or two such compounds may be caused to react consecutively. Alkaline reacting agents or nickel sulphate may be employed as catalysts. In an example, 2-mercaptobenzothiazole is dissolved in dioxane, absorptive carbon added and ethylene oxide passed into the solution at 96-105 DEG C.; insoluble material is, when reaction ceases, filtered from the hot solution, solvent removed and the residue heated to 90 DEG C. under 5 mm. pressure. The product is then recrystallized from benzene. Alternatively, monochlorobenzene, orthodichlorobenzene, tetrachlorobenzene or the diethyl ether of diethylene glycol may be used as solvent. The reaction of mercaptobenzothiazole with ethylene oxide in varying ratios in the presence of caustic potash is also described to yield products in which n varies from 1-15. Products may also be prepared as described in Specification 692,414.ALSO:Ferrous metals are pickled in a mineral acid solution containing a small proportion of a compound of the formula <FORM:0692413/II/1> where Ar is an ortho arylene group, R is an alkyline radical and n is an integer: R may be an ethylene group and n may be between 5 and 31. The preparation of these compounds is described, (see Group IV(b)), and Specification 692,414, [Group IV(b)], is referred to.
