In order to investigate the molecular structure and rotational isomerism, the electron diffraction camera having a rotating sector was designed and constructed and its application to some fluorochloroethanes was made successfully. The shortening of the C–F and the C–Cl bond by the substitution of...
The CAMD-step identifies real working fluids with similar performance as the optimal fluid. The best identified working fluid is chloroethane with anet power outputof 17.8MW, which is only 9% less than the output of the optimal fluid. The ranking of the working fluids according to their net ...
polychloroethane; under the protection of nitrogen, adding certain amount of the intermediate polychloroethane and ammonia water into a reactor and carrying out a heating reaction so as to obtain a solid mixture of polyethylenediamine and ammonium chloride; successively adding phenothiazine hydrochloride ...
The GC-MS analysis was performed on Agilent 7890 A Gas Chromatograph equipped with a HP-5 capillary column and a FID detector, with hexachloroethane (C2Cl6) added as internal standard to determine the light soluble “coke” amount. Prior to measurement, a calibration of GC-MS was performed...
13C NMR analysis of the polyethylene was recorded at 120 ◦C on a ARX 300 spectrometer operating at 75 MHz. The polyethylene samples were dissolved in 1,1,2,2,-tetra- chloroethane and 1,2,4-trichlorobenzene (25% v/v) in a 1.0 cm sample tube. The chemical shifts were referenced ...
the reaction byproducts such as sodium chloride, chlorohydrin, cyclochloroethane, glycol and the like can be easily removed once through a membrane separation technology, the obtained product has proper MS and a ratio of C2:C6, and the obtained product quality can reach or be superior to the ...
