  A study on the reducing abilities of tris(alkylthio)silanes

  摘要：

  Tris(methylthio)silane and tris(isopropylthio)silane effectively reduce a variety of organic substrates via free radical mechanisms. These silanes can also be used as hydrosilylating agents for alkenes having electron-donating substituents. The bond dissociation energy of the Si-H bonds have been measured by photoacoustic calorimetry and found to be around 83 kcal mol-1. The absolute rate constants for the reaction of the tert-butoxyl radical with (RS)3SiH have been measured by a laser flash photolysis technique and the optical absorption spectra of the corresponding radicals have been obtained. Multiple scattering X(alpha) calculations showed that the dominant absorption detected in the UV-vis region was due to sigma(Si-S)(e) --> SOMO and SOMO --> sigma*(Si-S)(e) transitions.

• Enhanced Coagulation on Reservoir Water by Dual Inorganic Coagulants

  This study evaluated the effect of enhanced coagulation on reservoir water using Al-2(SO4)(3), PACl, FeCl3, and PFS as coagulants. The treatment efficiencies were evaluated by the removals of soluble organic matter, turbidity, and bacteria. PFS was found to give better dissolved organic carbon (DOC) removal with less residual iron than FeCl3. Al-2(SO4)(3) performed best in removing turbidity, color, and bacteria, but was not, however, effective in DOC removal. When Al-2(SO4)(3) and PFS were combined, the best improvement in water treatment was achieved when PFS was added at the start of the rapid mixing and the Al-2(SO4)(3) was added sometime during the last 30 s of the rapid mixing. It was also discovered that a combination of high dose of PFS and low dose of Al-2(SO4)(3) gave efficient enhanced coagulation.
