Related Products of 1806-29-7, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 1806-29-7, Name is 2,2-Biphenol, molecular formula is C12H10O2. In a Patent,once mentioned of 1806-29-7
The invention discloses a double-phosphorous acid ester synthetic method, the method uses reagent of phosphorus trichloride, 2,2 the and-biphenol […] 3,5-di-tert-butyl -3 ?, 5 ?-dimethoxy -2,2 ?-biphenol as raw materials, the phosphorus trichloride is dissolved in water to form a solution in organic solvent, then added to the solution under stirring with a 2,2 the-biphenol […] and organic alkali, in organic solution, phosphorus trichloride solution is added after the completion, stirring for several hours to continue the reaction solution; to the above-mentioned reaction solution is added with 3,5-di-tert-butyl -3 ?, 5 ?-dimethoxy -2, an organic solution of 2 ?-biphenol, after the completion of addition, the reaction solution is continuously stirred for several hours, subsequently heating up to 80-120 C reflux for several hours; after the reaction the reaction cooling to room temperature, filtered, washing the filter cake, combined filtrate is concentrated by evaporation of solid, solid acetonitrile washing, recrystallization to obtain the product. The process of the invention with double phosphite high ester production rate, phosphorus trichloride there is little consumption, there are few by-products, the reaction time is short, after treatment is simple, and the like.
