Abstract
1318676 Any-foaming agent for pickling HENKEL & CIE GmbH 1 Feb 1972 [2 Feb 1971] 4593/72 Heading C7E An acid pickling solution contains a wetting agent, and as anti-foaming agent, a mixture of octadecanediol-1,12 and a paraffin oil. The acid may be HCl, H 3 PO 4 , or H 2 SO 4 , the wetting agent may be ethoxylated nonyl phenol with or without an alkylbenzene sulphonic acid, the paraffin oil preferably has viscosity 100-200 cSt at 20‹C, the ratio octadecanediol-1,12 to paraffin oil may be 4:1 to 1:3, and the solution may contain 0À5-10% of the anti-foam agent based on the weight content of wetting agent and 0À05-2% based on the weight content of acid. The solution may also contain a chlorohydrocarbon such as trichloroethylene.
