Flash Vacuum Thermolysis of Phenylcyclopropanecarbaldoximes and Its Methyl Ethers

Flash vacuum thermolysis of 1-phenylcyclopropane-1-carbaldoxime at 500 °C produced mainly 3-phenylpyrrole. The products after thermolysis of its oxime methyl ether were α-methoxymethylstyrene, α-methylstyrene, and a dimer 2,5-dipheny 1-1,5-hexadiene.     

Triplet excited states and radical intermediates formed in electron pulse radiolysis of amino-substituted fluorenones

Electron pulse radiolysis of four differently substituted amino derivatives of fluorenone, namely, 1-amino-, 2-amino- 3-amino-, and 4-aminofluorenone, has been carried out to study the effect of structure on the spectroscopic and kinetic characteristics of the triplet excited states as well as the transient free radical intermediates formed under reducing and oxidizing conditions. The triplet states of these compounds have been generated in benzene by pulse radiolysis and in other solvents by flash photolysis technique and their spectral and kinetic properties have been investigated. Hydrated electron (e_aq⁻) has been found to react with these fluorenone derivatives to form the anion radical species with a diffusion-controlled rate constant. The spectral and kinetic properties of the transient ketyl and anion radicals have been studied by generating them in aqueous solutions of suitable pH. The pK_a values of ketylanion radical equilibria are in the range of 6.8–7.7 for these derivatives. The oxidized species have been generated by reaction with the azide radical. Hydrogen atom adducts as well as the cation radicals of these derivatives have also been generated by pulse radiolysis and characterized.     

气体流动热量计和苯、苯-环己烷气体热容的测量

随着化学热力学理论研究的深入和石化工业的迅速发展,混合物热力学性质的实测数据日显短缺.气体热容的测量一直为人们所重视,先后出现了各种各样的测量方法,其中以流动量热法最突出,发展也较完善.对于混合气体热容的测量,国际上尽管有一些文献报导,但由于没有解决好稳定混合气流的产生问题,测量对象仅为一些沸点相近的二元物系,且测量温度不高,很难推广到多元物系乃至不定组成物系如石油馏分的测量.本文依据Powers等人热量计和Clarke 快速蒸发器的设计原理,从结构上进行了一些改进.并将两者有机地结合起来,建立了一套可在中、低压下测量各种气体热容的金属量热装置.
