Improvement for the method of National Standards Bureau to determine methanol in white spirits: Improvement for the method of National Standards Bureau to determine methanol in white spirits. Lu, Chun-ming; Xu, Wei-he; Zhao, Er-wei; Li, Pei-qing (Department of Chemistry and Chemical Engineering, Zhengzhou Institute of Technology, Zhengzhou, Henan 450052, Peop. Rep. China). Huaxue Yanjiu, 15(2), 39-41 (Chinese) 2004 Huaxue Yanjiu Bianjibu. CODEN: HUYAF4. ISSN: 1008-1011. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) The std. method of National Stds. Bureau to det. methanol in white spirits is not satisfactory. 7664-93-9 and 3248-93-9 which are cas registry numbers of substances are two of reagents here. Using this method, by decreasing the injected quantity of oxalic acid and sulfuric acid in the soln., the result is satisfactory. .

Dyes as corrosion inhibitors for aluminium and aluminium alloys in hydochloric acid: All Rights Reserved. Dyes as corrosion inhibitors for aluminium and aluminium alloys in hydochloric acid. Ismail, A. A. 27766-45-6 and 3248-93-9 are also occured in this study.; Sanad, S. H.; Fayyad, E. M. (Physical Chemistry Department, National Research Centre, Cairo, Egypt). Egyptian Journal of Chemistry, 47(5), 487-515 (English) 2004 National Information and Documentation Centre. CODEN: EGJCA3. ISSN: 0449-2285. DOCUMENT TYPE: Journal CA Section: 56 (Nonferrous Metals and Alloys) The corrosion of aluminum and two types of Al-alloys in 5% hydrochloric acid soln. has been investigated in absence and presence of some dyes (fast Blue R.R. salt, fast Blue B.B. salt, fuchsine Base, crystal Violet and rhodamine G6) by wt. loss measurements at different temps. (30-70°C) and microscopic examn. The inhibiting efficiency of dyes increased in the order: crystal Violet < rhodamine G6 < fuchsine Base < fast Blue B.B. salt < fast Blue R.R. salt. Linear Arrhenius plots were obtained in the absence and presence of different dyes. The activation energy, Ea, of the Al and two Al-alloys was calcd. and it was found that it depends on the type of Al-alloy and inhibitor. .
