Synthese des aldehydes et des acides marques a partir de CH₄−¹⁴CO₂−Ar par decharges electriques moderees

Abstract

The following results of distribution of initial activity (μCi) in the synthesis products have been obtained: Initial¹⁴CO₂−490.0±65.0, final gas−142.4±35.0, products−134.1±22.0 (C₁−29.3; C₂−5.7; C₃−9.6; C₄−9.8; C₅−6.4; C₆−6.9; C₇−2.0; not identified products−54.4); carboxyl products −25.7±3.6 (C₁+C₂−2.2; C₃−10.1; C₄−0.4; C₅−0.8; C₆−2.5; C₇−7.6; C₈−1.4; C₉−0.6); deposit of polymers on the surface of the ozonator −52.3±8.2. The mean values of specific activity of the carbonyl and carboxyl fractions has nearly the same values of activity as the initial¹⁴CO₂ (27.0±3.6 Ci/mM), the specific activities of carbonyl products increased from 15±4 (C₁) to 60±15 (C₆) μCi/mM. The IR and mas-spectra of the polymeric product are given.
