The reaction in aqueous solutions between carbon disulphide and morpholine has been studied experimentally at 303 K using a conductimetric stopped‐flow technique. The observed pseudo‐first order rate constant does not vary linearly with amine concentration but follows the equation:\documentclass{article}\pagestyle{empty}\begin{document}$$ k_{obs} = k_{Am} [R_2 NH]^2 + k_w [R_2 NH][H_2 O] $$\end{document}. This equation is compatible both with (i) zwitterion intermediate and (ii) single‐step termolecular reaction mechanisms which were previously proposed for the corresponding reactions of CO 2 and COS. Values of rate constants k Am and k w at 303 K are also reported.
