Chapter two 4-Hydroxybenzoic acid is connected with PEG6000 through defoliant DCC at rooom temperature, then the product is refluxed with chloroacetic acid in acetone to afford PEG-bound phenyloxyacetic acid, which is reacted with thionyl chloride, ammonium thiocyanate and arylamines in turn to give PEG-bound disubstituded thioureas. After the cleavage with sodium methoxide in methanol, the eleven disubstituted thioureas are obtained.

第二章 利用PEG6000作载体，通过脱水剂DCC在室温下将对羟基苯甲酸以酯键连接在PEG6000上，再与氯乙酸在较温和的条件下生成PEG6000支载的芳氧乙酸，然后，依次与亚硫酰氯、硫氰酸铵、芳胺反应，生成PEG6000支载的硫脲，最后用甲醇钠的甲醇溶液切割PEG，得到了十一种1，3-二取代硫脲。

The concentrations of CO2, CF4, thionyl sulfide (SOF2), sulfuryl fluoride (SO2F2), disulfuryl decafluoride (S2OF10), sulfur dioxide (SO2) and sulfureted hydrogen (H2S) were in partial normal distribution. The concentrations of CO2, CF4, SOF2, SO2F2, S2OF10 were all below 0.1%; the concentrations of SO2 were below 3μL/L; the concentrations of H2S were below 1μL/L. The SF6 byproducts concentrations in 500kV GIS were lower than those in 220kV GIS. The SF6 byproducts concentrations were lower in GIS that have been operating longer. The SF6 byproducts concentrations were significantly different in equipment from different manufacturers.
