In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 496-41-3, name is Benzofuran-2-carboxylic acid, introducing its new discovery. Safety of Benzofuran-2-carboxylic acid
Preparing a cosmetic additive 2 – (benzofuran -2 – yl) benzoxazole new method (by machine translation)
The invention relates to a technical field of fine chemicals, discloses a process for preparing cosmetic additive 2 – (benzofuran – 2 – yl) benzoxazole new method. Specific steps: to benzoxazole with benzofuran – 2 – carboxylic acid as the raw material, nickel chloride as catalyst, silver carbonate and 1, 3 – double (2, 6 – diisopropyl phenyl) imidazole chloride as an additive, in chlorobenzene 160 degree Celcius reaction 20 hours, to obtain 2 – (benzofuran – 2 – yl) benzoxazole. Compared with the prior art, this method has simple and rapid, one-step direct constructing target product. In addition, the use of inexpensive, easy to store of the carboxylic acid as the coupling reagent, with potential industrial value, is worthy of application. (by machine translation)
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 496-41-3, and how the biochemistry of the body works.Safety of Benzofuran-2-carboxylic acid
