Chim.Several reagents with their cas registry numbers 90-15-3 and 4089-04-7 are used here. (Bucharest), 34(12), 1116-19 (Romanian) 1983. CODEN: RCBUAU. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 80 Oltitox [63-25-2] was sepd. from impurities, i.e., di-1-naphthyl [3159-41-9] and di-2-naphthyl carbonate [3159-41-9], 2-naphthyl N-methylcarbamate [4089-04-7], 1-naphthol [90-15-3], and 2-naphthol [135-19-3], by TLC on Silica gel G or Anosil (colloidal atomized silica), using CHCl3-benzene (1:1) mobile phase. Rf Values are tabulated. The Romanian product Anosil was as suitable for the sepn. as was Silicogel G. .

DOCUMENT TYPE: Report CA Section: 61 (Water) Section cross-reference(s): 51, 60, 80 An anal. method was developed for anal. of org. compds. in aq. leachates of fossil fuel solid wastes. The method was evaluated using 2 synthetic leachates as well as bulk and small-scale leachates of SRC-II vacuum still bottoms at the participating labs. Under the conditions of these tests, the method worked well for most analytes; however, n-hexanoic acid [142-62-1], 4-aminobiphenyl [92-67-1], 1,4-naphthoquinone [130-15-4], and 1-naphthylamine [134-32-7] were not det. accurately or precisely by the method. Other analytes of interest are o-cresol [95-48-7], phenanthrene [85-01-8], carbazole [86-74-8], naphthalene [91-20-3], n-tetradecane [629-59-4], 2-naphthol [135-19-3], dibenzothiophene [132-65-0], quinoline [91-22-5], acenaphthylene [208-96-8], 2-picoline [109-06-8], fluoranthrene [206-44-0], benzanthracene [56-55-3], PhOH [108-95-2], 2,3,4,8-tetrachlorobiphenyl (std.In this experiment, several chemicals are used like 91-22-5 and 208-96-8 ), 2-fluorophenyl (std.), n-octacosane (std.), and azulene (std.). .
