Micro-syntheses for the use of carbon 13 or carbon 14. Micro-preparations of methyl alcohol, methyl iodide, and sodium acetate labeled in the methyl group
Description
Apparatus and technique are described in detail for (1) reduction of CO2 to CH3OH with LiAlH4, (2) conversion of the methanol to CH3I by HI, (3) formation of the Mg Grignard reagent, and (4) addition of inactive CO2 to form CH3COOH. All these operations have been carried out on 0.005 moles. Methyl-labeled Na acetate has been prepared in 67% yield based on the Ba14CO3 used as starting material. (author)

Description detaillee d'une technique deja connue pour la reduction du gaz carbonique en alcool methylique par LiAlH4. Conversion du methanol en iodure de methyle. Ce dernier transforme en reactif de Grigard, et carbonate, fournit de l'acide acetique. Toutes ces operations on ete effectuees sur 5 x 10-3 moles. La methode a ete appliquee a la synthese d'acetate de sodium marque par le groupement methyle par 14C avec un rendement global de 67% base sur le carbonate de baryum radioactif mis en oeuvre.
