Electric Literature of 1806-29-7, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.1806-29-7, Name is 2,2-Biphenol, molecular formula is C12H10O2. In a patent, introducing its new discovery.
The invention discloses a double-phosphite ester synthesis method, the method uses reagent of phosphorus trichloride, 2, 2 ‘- biphenol and 3, 3’, 5, 5 ‘- uncles butyl – 2, 2’ – biphenol as raw materials, the phosphorus trichloride is dissolved in the organic solvent to form a solution, then is added under mixing to dissolved with the 2, 2 ‘- biphenol, organic alkali and catalyst in organic solution, phosphorus trichloride solution after the adding, the reaction solution to continue the reaction for several hours; adding to the above-mentioned reaction solution is dissolved with the 3, 3’, 5, 5 ‘- uncles butyl – 2, 2’ – biphenol organic solution, after the adding, the reaction solution to continue stirring for several hours, then heated to 80 – 120 C reflux for a few hours; after the completion of the reaction the reaction cooling to room temperature, filtered, washing the filter cake, the filtrate after the merger of the evaporation concentration to obtain the solid, solid acetonitrile washing, recrystallization to obtain the products. The process of the invention has double-phosphite ester production rate high, phosphorus trichloride is little consumption, few by-products, the reaction time is short, simple post-treatment and the like.
