Scientific paper

The authors report the results of a laboratory study of some ion-molecule reactions relating to the production and loss of HCl in interstellar clouds. It is found that H2Cl+ ions (which are probably formed in interstellar clouds via the reactions of Cl+ and HCl+ with H2) rapidly transfer protons to CO molecules at low temperatures, and so this process, rather than dissociative recombination, is dominant in the production of HCl from H2Cl+ in dense interstellar clouds. The reactions of H+, H3+, C+ and CH3+ with HCl have also been studied, since they are possible destruction processes for HCl.
