程序升温液相反应技术

Temperature Programmed Liquid Reaction Technique

液相反应在化学反应中占有极其重要的地位,而有气体消耗或逸出的液相反应在实际生产过程和实验室研究中屡见不鲜,对于此类反应的研究常采用稳态定温手段求取动力学参数,但耗费大量的时间和精力.为此,本文提出了适合此类反应的程序升温液相反应(TPLR)技术.

The technique of Temperature Programmed Liquid Reaction is advanced in thias paper and the calculating method of reaction kinetic parameters from the curves of TPLR is established at the same time.The advantage of this technique is that some kinetic parameters such as activation energy,frequency factor and reaction order are obtained by means of a TPLR experiment.In comparison with classical steady state method,the TPLR,dynamic state technique,has many advantages such as fast,handy and so on.The instrument used in this technique,the work principles,operational conditions and process diagram are described.Feasibility of TPLR technique is illustrated by handling the liquid reaction system of decomposition of phenyl diazonium chloride.The calculated results of kinetic parameters are compared with that obtained by other authors and the results is proved to be reliable.
