Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1806-29-7, Name is 2,2-Biphenol, Recommanded Product: 1806-29-7.
The invention discloses a 2,2 ?-bis (benzo [d, f] [1, 3, 2] unites non-Si -6-yloxy) – 1,1 ?-biphenyl method for synthesizing intermediate, the steps of : (1) measure 2, the 2-biphenyl-diphenol […], then adding phosphorus trichloride solution of the product of the reaction of 6-chloro -5,7-dioxo-6-phosphate-diphenyl heterocycle heptenonic ; (2) re-weighing 2, the 2-biphenyl-diphenol […] the quality of such as 2, the 2-biphenyl-diphenol […], completely dissolved in the mixed solvent of toluene and a tertiary amine, to form the mixed solution of three ; (3) the step (1) product is in responds the bath, gradually dropped after step (2) of the mixed solution, after the dipping to be completely, closed low-temperature thermostatic responds the bath, and to continue the reaction to obtain the product 2,2 ?-bis (benzo [d, f] [1, 3, 2] unites non-Si -6-yloxy) – 1, and-biphenyl 1 ? purifying the product. Output rate by this method is as high as 80% or more. (by machine translation)
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Recommanded Product: 1806-29-7. In my other articles, you can also check out more blogs about 1806-29-7
