权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:A process for synthesis of an organosilicon compound is provided herein. Also, novel organosilicon compounds prepared by the present process is provided herein. The process comprises the reaction of a halosilane with an organofunctional alkyl halide in the presence of a metal catalyst, a promoter, and an optional co-catalyst. The process provides an efficient synthetic route to produce organosilicon compounds. The process also allows synthesis of organosilicon compounds with a plurality of different functional groups.

摘要:The process for synthesizing a poly(amic acid) polymer or a polyimide polymer is improved by using a solvent system consisting essentially of: (A) a first component consisting essentially of at least one of a sulfoxide, e.g., DMSO, and an alkyl phosphate, e.g., triethyl phosphate, and (B) optionally, a second component consisting essentially of at least one aprotic glycol ether, e.g., dipropylene glycol dimethyl ether.

标题:Process for removal of hydrogen sulfide from gases
发明人：LYNN SCOTT
权利人:UNIV CALIFORNIA
摘要:Two stage removal of hydrogen sulfide from a gas. In the first stage solutions of hydrogen sulfide and sulfur dioxide in a solvent react to produce sulfur and water. An excess of hydrogen sulfide is maintained in the first stage resulting in a solution containing sulfur, water and the excess hydrogen sulfide, or resulting in a gas containing the excess hydrogen sulfide. The excess hydrogen sulfide in the solution or in the gas is then treated in a second stage with a solution in the same solvent of sulfur dioxide in excess of or closely equal to that required to react with the hydrogen sulfide. Excess sulfur dioxide in the vapor phase from the second stage may be absorbed in neat solvent. The solvent is selected to have a high solvating power for sulfur dioxide, a lesser but substantial solvating power for hydrogen sulfide and to promote the reaction of hydrogen sulfide with sulfur dioxide. Such gases as natural gas, synthesis gas, and the tail gas of a claus plant may be so treated. By appropriate selection of solvents and/or conditions, accompanying minor components of the gas stream being treated may be removed and recovered if of value, e.g., propane from natural gas, carbon dioxide and water from synthesis gas, etc. The process avoids the need to maintain exact stoichiometric ratios of hydrogen sulfide and sulfur dioxide, it avoids the need to use high flow rates of solvent, a liquid phase capacitance for hydrogen sulfide is provided which dampens the effect of fluctuations in hydrogen sulfide content in the gas stream, etc.

摘要:The present disclosure describes methods of polyimide synthesis and polyimides made therefore. The method includes placing a tetracarboxylic compound and a solvent in a reaction vessel and adding a first amount of a diamine. The first amount of the diamine is not more than 99.5 mol % of the tetracarboxylic compound inside the reaction vessel. The method can include agitating the mixture and determining a viscosity of the mixture. The method can further include adding a second amount of the diamine. The last steps can be repeated until the viscosity increases to a target value. The target viscosity can be correlated to a peak weight-averaged molecular weight of the polyimide.
