Abstract: The invention relates to the production of bright zinc-plated or zinc-alloy-plated shaped parts by the electrolytic desposition or zinc or a zinc alloy from an acidic aqueous galvanic bath containing as its essential components one or more zinc salts and optionally salts of other alloy metals, one or more conducting salts, one or more surface-active agents and one or more brighteners. Used as brighteners are compounds of the formula (I), in which R is a C1-C8 alkoxy, phenoxy, benzyloxy, amino, C1-C6 alkylamino or di(C1-C6) alkylamino group; R is a C1-C4 alkyl, phenyl or benzyl group or one of the groups given for R ; Ar is a phenyl or naphthyl group which may be substituted by one to three C1-C4 alkyl or C1-C4 alkoxy groups.

Abstract: Tetrachloro-3-imino- isoindolin-1-one (I) or its alkali metal salts (Ia) is prepd. by reacting tetrachloro-orthophthalodinitrile (II) with LiOH, NaOH and/or KOH in substantially anhydrous tert. butanol as solvent, and opt. liberating the (I) from the (Ia) formed by treatment with a dil. acid: M = Li, Na, K. Pref. the finely divided alkali metal hydroxide is used in an amt. of 1.0-5.0 mol. per mol. (III), and the tert. butanol has a water content of less than 5 wt. % and is used in an amt. of 5-15 times the wt. of (II). The reaction is carried out at 26-80 deg. C.
