结果在低氯离子浓度（< 0.2 M）条件下，采用带磁搅拌棒的折痕烧瓶对乙烯的吸收速率进行传质控制。然而，当采用专门为气液转移设计的高速反应器时，发现反应包括非常快速的初始乙烯吸收，随后是较慢的乙烯吸收。最初吸收的乙烯体积超过了用乙烯使溶液饱和所需的体积。超出溶解度要求的乙烯吸收量发现不受酸浓度的影响，但随着氯离子浓度的增加而减少。
Results At low chloride ion concentration (< 0.2 M) the rate of ethylene uptake was mass-transfer controlled when creased flasks with magnetic stirring bars were used.However, when a high speed reactor especially de-signed for gas-to-liquid transfer was employed, the re-action was found to consist of a very rapid initial ethyl-ene uptake followed by a slower ethylene absorption. The volume of ethylene initially taken up exceeded that required to saturate the solution with ethylene. This volume of ethylenetaken up in excess of solu-bility requirements was found to be unaffected by acid concentration but decreased as the chloride ion con-centration increased.
