Nitric acid system for etching magnesium plates

Nitric acid system for etching magnesium plates. Czirr, David L.; Kroll, Harry (Hunt, Philip A., Chemical Corp., USA). U.S. US 4032379 28 Jun 1977, 20 pp. Division of U.S. 3,935,118. (English). (United States of America). CODEN: USXXAM. CLASS: IC: B41C001-00. NCL: 156659000. APPLICATION: US 73-337879 5 Mar 1973. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) Photoengraved letter-press printing and pattern plates of Mg and Mg alloys contg. .ltoreq.95% Mg are etched by directing a HNO3-contg. aq. soln. against the surface. The etching soln. also contains (1) nonreactive C6-26 fatty monocarboxylic acid (2) organophosphoric acid (3) alkylaryl sulfonic acid (4) surfactant or coupling agent. Thus, a fresh etching soln. contg. HNO3 170, hexyl cellosolve [112-25-4] 2.2, butyl carbitol [112-34-5] 4.5, caprylic acid [124-07-2] 0.Some commonly used reagents like 27253-43-6 is used in this experiment.6, triethanolamine salt of sulfonataed oleic acid (surfactant) 2.1, isopropylamine dodecylbenzenesulfonate [26264-05-1] 2.5, isostearic acid [30399-84-9] 5.1, polyethylene glycol mono(tert-octylphenyl) ether [9036-19-5] 1.7, and 1-hydroxyethane-1,1-diphosphonic acid [2809-21-4] 3.3 g/L was used to etch Mg plates for newspaper type. The etching depth was 7.5 mils, which gave satisfactory images. After letting the soln. stand idle for 18 h, the etching depth was 9.0 mils. Similar prior-art solns. not contg. the organophosphoric acid had etching depths of 12-16 mils which gave unacceptable images. .

CLASS: IC: B01F017-34; B01F017-12. APPLICATION: DE 83-3320601 8 Jun 1983. PRIORITY: GB 82-17136 12 Jun 1982. DOCUMENT TYPE: Patent CA Section: 61 (Water) Section cross-reference(s): 46, 51 A dispersing agent for petroleum and petroleum products in cold seawater contains a nonionic surfactant comprising C12-20 fatty acid esters of polyalkoxylated sorbitol or sorbitan 8-28; an anionic sulfonate salt surfactant 7-53; C5-10 alcs., glycol, or glycol ether solvents 85-30; and water 0-15%. Thus, a mixt. of Atlox G 1086 [57171-56-9] (polyoxyethylated sorbitol hexaoleate) 37.5, Arylan PWS (isopropylamine dodecylbenzenesulfonate) [26264-05-1] 22.5, and Butyl Oxitol [111-76-2] 40% gave 90% effectiveness in a Mackay dispersant effectiveness test with Kuwait crude.
