(Germany). CODEN: GWXXBX. CLASS: IC: C23G001-10. PRIORITY: JP 76-2737 14 Jan 1976. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) Methylcyclohexanol [25639-42-3] and/or cyclohexanol [108-93-0] 0.1-5 g/L are added to an acid H2O2-contg. soln. for etching Cu and Cu alloys. The addn. prevents the retarding effect of trace chloride impurities in the soln. Thus, oxidized Cu-40Zn [12621-84-0] was dipped 1 min. at 40° in an aq. soln. contg. H2O2 20, HNO3 70, nonionic surfactant 1, cyclohexanol 0.5 g/L, 2-ethoxyethanol 10 mL/L, and Cl- 5 ppm. Etching was satisfactory. The same soln. without cyclohexanol did not dissolve the surface oxide.
