Basis for the maximum permissible concentration of ethyl, isopropyl, isobutyl and isoamyl xanthogenates of potassium in rats. Ovanesyan, R. D. (NII Obshch. Gig. Profzabol., USSR). Zh. Eksp. Klin. Med., 24(4), 344-8 (Russian) 1984. CODEN: ZKMAAX. ISSN: 0514-7484. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Section cross-reference(s): 59 Acute toxicity of K Et xanthogenate [140-89-6], K iso-Pr xanthogenate [140-92-1], K iso-Bu xanthogenate [13001-46-2] and K isoamyl xanthogenate [928-70-1] (used for flotation enrichment of Cu-Mo ores) decreased in correlation with mol. wt. of the compds. Chronic inhalation of K Et xanthogenate (13.65 mg/m2, 1-3 mo) caused decreases in body wt., O consumption, urinary concn. of hippurate [495-69-2], and hepatic activity of MAO [9001-66-5] and increases in serum concn. of free SH-groups, blood sugar concn., mortality of fetuses, and the no. of chromosome aberrations. Max. permissible concns. recommended for Et xanthogenate and for the other 3 xanthogenates are 0.5 and 1.0 mg/m3, resp.

Several applications of some ion-selective liquid membrane electrodes for the analysis of organic compounds

Several applications of some ion-selective liquid membrane electrodes for the analysis of organic compounds. Cosofret, Vasile V.; Zugravescu, Paul G. (Rom.). Rev. Chim. (Bucharest), 28(8), 785-9 (Romanian) 1977. CODEN: RCBUAU. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Six pharmaceuticals and intermediates in pharmaceutical synthesis, i.e. ethanolamine-HCl [2002-24-6], 2-chloroethylamine-HCl [870-24-6], p-acetylaminobenzenesulfonyl chloride [121-60-8], 6-phenyl-2,3,5,6-tetrahydroimidazo[2,1-b]thiazole-HCl [4641-34-3], 4'-(b-piperidinoethoxy)-2-carbomethoxybenzophenone-HCl [1248-42-6], and 2,2-diphenyl-4-piperidinobutyramide-MeBr [125-60-0], were detd. potentiometrically, using Ag+- and Hg2+-selective electrodes with liq. membranes (Cosofret, V.V., 1976). Trans-1-chloro-1-hepten-3-one [65316-84-9], an intermediate in prostaglandin synthesis, was reduced with NaBH4, and detd. potentiometrically using a Ag+-selective electrode. The error was ±0.5% for 1.6-11.4 mg samples. K isobutylxanthogenate [13001-46-2] was detd. with a Cu2+-selective electrode using as a membrane Cu(II) salicylaldoximate in CHCl3. The titrn. was carried out with 10-2 M CuSO4. 6-Carbethoxy-as-triazine-3,5(2H,4H)-dithione [29769-65-1] was titrated with 10-2 M AgNO3 in a NaOAc-HOAc buffer (pH 6), using an Ag+-selective electrode, and Ag dithizonate in CCl4 as membrane.
