Use of 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine for the determination of iron in wines

Use of 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine for the determination of iron in wines. Mandrou, B.; Fabre, H.; Mattras, H. (Lab. Chim. Anal. Toxicol., Fac. Pharm., Montpellier, Fr.). Ann. Falsif. Expert. Chim., 69(738), 219-28 (French) 1976. CODEN: AFECAT. DOCUMENT TYPE: Journal CA Section: 16 (Fermentations) 3-(2-Pyridyl)-5,6-diphenyl-1,2,4-triazine (I) [1046-56-6] was used to detn. Fe in wine according to the method of Schilt and Taylor (1970), with the exceptions of extg. with EtOAc instead of isoamyl alc. and asking with H2O2 instead of by heat alone. The method gives results comparable to other colorimetric methods. The Cu levels of wine do not interfere. The method is 1.7 times more sensitive than the std. o-phenanthroline method. However, it is not recommended because it requires the extn. step, and the greater sensitivity is of no consequence with respect to the Fe levels found in wine.

Electroless copper coating bath

Electroless copper coating bath. 60-00-4 which is the cas registry number of one of substances is just one of reagents here. (Toshiba Corp., Japan). Jpn. Kokai Tokkyo Koho JP 59059872 A2 5 Apr 1984 Showa, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C23C003-02. APPLICATION: JP 82-169866 30 Sep 1982. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) Section cross-reference(s): 76 The bath contains water-sol. Cu salt, complexing agent(s) for Cu2+, reducing agent(s), pH adjusting agent(s), and 31 complexing agent(s) for Cu1+ selected from (I), (II), and (III) [R,R1 = H, substituted phenyl; R2 - R5 = H, lower alkyl; R6, R7 = H, substituted arom.; R8, R9 = lower alkyl]. Coating with Cu at high rates is possible, and the coatings have excellent mech. properties. The bath is useful for manufg. printed elec. circuit wiring boards. Thus, a paper-epoxy resin type laminated circuit board was surface roughened in an aq. soln. of CrO3 and H2SO4, rinsed, redn. treated in an aq. NaHSO3 soln., rinsed, sensitized in an aq. soln. of SnCl2 and HCl, rinsed, immersed in an aq. soln. of PdCl2 and HCl, rinsed, and coated with Cu in a bath at pH 12.3 and 70° contg. CuSO4.5H2O 10, EDTA [60-00-4] 32, HCHO 1.5 g/L, and 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine [1046-56-6] 30 mg/L. The coating rate was 3.7 m/h, and the Cu coating had an elongation of 3.5% and tensile strength of 33 kg/mm2. .
