RADIOACTIVE TRACER STUDY ON THE PHOTOCHEMICAL REACTION OF ¹⁴CS₂ WITH OH IN THE PRESENCEOF O₂

摘要：用放射示踪法研究¹⁴CS₂和OH的光化学反应,指出氧对反应有促进作用,在反应体系中(¹⁴CS₂-H₂O₂-C₃H₈-N₂-O₂)主要产物为O¹⁴CS,¹⁴CO及少量¹⁴CO₂。O¹⁴

Abstract：The photochemical reaction of ¹⁴CS₂ with OH has been studied. The results indicated that the main products of the reaction were O14CS and 14CO with a small amount of ¹⁴CO₂ in the reaction system (¹⁴CS₂-H202 -C₃H8-N2-O₂) .The reaction was promoted by oxygen. O¹⁴CS₂ and 14CO had the similar kinetic curves while 14CO, got a different kind. The overall rate constant increased with the increasing of oxygen pressure. The rate constant for the removal of ¹⁴CS₂ was k1 = 3.4 × 10^-12cmimolecule-1s-1 at 33330 Pa O₂. The conversion of ¹⁴CS₂ to ¹⁴CO₂ at room temperature was observed and the possible mechanism of the photochemical reaction was discussed.
