Abstract

1,259,676. Modifying copper surfaces. OBAYASHI GUMI K. K., KAJIMA KENSETSU K. K., SHIMIZU KENSETSU K. K., TAISEI KENSETSU K. K., TAKENAKA KOMUTEN K. K. and PARKER KAKO K. K. Jan. 10, 1969 [March 6, 1968], No. 1684/69. Heading C7U. Verdigns is formed on a copper or copper alloy surface by contacting with a solution (pH 4 to 5) containing ammonium and copper sulphate and mercuric chloride and then drying in an oxygen containing atmosphere. The verdigns so formed may be treated with a solution containing an alkyl (ethyl) nitrite, Examples of solutions are (g/l): (a) (NH 4 ) 2 SO 4 70, CuSO 4 SH 2 O 2 , HgCl 2 5, and (b) NH 4 Cl 15, NaCl 50, Cu(NO 3 ) 3H 2 O 100 to which 100 c. c. of 15% alcoholic ethyl nitrite is added. The first solution is dried for 10 to 30 minutes at 5 to 35‹ C. at a humidity of 50 to 90%.
