Method and composition for inhibiting corrosion: Method and composition for inhibiting corrosion. Coffey, M. Dewayne; Kelly, Mary Y.; Kennedy, Weldon C., Jr. (Dow Chemical Co., USA). U.S. US 4493775 A 15 Jan 1985, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: ICM: C09K003-00. NCL: 252008550C. APPLICATION: US 83-537887 30 Sep 1983. DOCUMENT TYPE: Patent CA Section: 55 (Ferrous Metals and Alloys) An improved corrosion inhibitor for ferrous metals in acidic environments contg. H2S is described. Thus, a reaction mixt. (50 vol.%) contg. acetophenone 53.51, paraformaldehyde 29.4, cyclohexylamine 7.7, tall oil 1, and HCl 8.39% at 220 °F was used to prep. an inhibitor contg. 4-ethyl-1-octyn-3-ol [5877-42-9] 12.5, formalin [50-00-0] 10, isopropanol 12.5, and nonionic surfactant Tergitol TMN6 [60828-78-6] 15 vol. %. Specimen of J 55 [61287-14-7] was placed for 24 h in 100 mL 15% HCl soln. contg. the inhibitor 0.2 vol.%. The corrosion rate was lower than that for a conventional inhibitor contg. no acetylenic alc.
