Acute intoxication from antimony trichloride.
an additional, slightly delayed onset of gastro-intestinal disturbance including abdominal pain and persistent anorexia. Urine antimony estimations revealed a concentration in excess of i mg./litre in these five men. Environmental measurements suggest that they were briefly exposed to air containing up to 146 mg. hydrochloric acid and 73 mg. antimony per m.3 expressed as the metal. These findin...
متن کاملThe colorimetric reaction between vitamin A2 aldehyde and antimony trichloride.
1. Columns of Sephadex G-25 have been used for the preliminary fractionation of tryptic digests of casein. 2. Fractions from Sephadex columns have been examined for their ability to stimulate the growth of a strain of Streptococcus equi8imili8. Maximum stimulatory activity appeared to be localized in a fairly narrow region of the total peptide material. 3. Further fractionation of peptides deri...
متن کاملStudies on the reaction of certain carotenoids with antimony trichloride.
Since both carotene and vitamin A yield a blue color with SbCla, attempts to determine t,he vitamin quantitatively in a mixture depend, among other things (1, 2)) upon the accuracy with which the blue color due to carotene can be estimated. Values published for the blue equivalent of carotene range from 3.5 to 13, calculated as micrograms of apparent vitamin A per 100 y of carotene (3). This di...
متن کاملDirect coupling of alcohols with alkenylsilanes catalyzed by indium trichloride or bismuth tribromide.
Indium halides or bismuth halides catalyzed the coupling of various alcohols with alkenylsilanes to give the corresponding alkenes stereospecifically without any other activators.
متن کاملAn Efficient Synthesis of 3,4-Dihydropyrimidin-2-(1H)-one Derivatives Promoted by Antimony Trichloride under Thermal and Solvent-free Conditions
An efficient and simple one-pot approach for the synthesis of 3,4-dihydropyrimidin-2-(1H)-one derivatives using antimony trichloride (SbCl3) as a mild catalyst by means of three-component Biginelli reaction between β-keto esters, aldehyde derivatives and urea/thiourea under thermal and solvent-free conditions with excellent yields and short reaction times is reported. This m...
