Chemical Research Letters, May 2021. 22990-19-8, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.22990-19-8, Name is 1-Phenyl-1,2,3,4-tetrahydroisoquinoline, molecular formula is C15H15N. In a Patent，once mentioned of 22990-19-8
The present invention provides a 1-phenyl -1, 2, 3, 4-isoquinoline method for the preparation of, the, benzoyl chloride or benzoic acid, phenethylamine, alkali metal hydroxide is mixed with water, after the reaction, to obtain N-(2-phenethyl) benzamide; then with the phosphorus pentoxide, phosphorus chloride and benzene solvent mixed, the heating reaction, to obtain 1-phenyl -3,4-dihydro-quinoline; further and 1st alcohol solvent and borohydride mixing, the product is obtained after the reaction. Compared with the prior art, first of all, the invention does not add any organic solvent and the product N-(2-phenethyl) benzamide not dissolved in aqueous solution, therefore in post-treatment process in the steps such as the liquid does not need to be, the advantages of simplifying the post-processing operation; secondly, without the added organic solvent the cost is also reduced, to avoid the pollution of the environment; once again, adopts a phosphorus pentoxide and phosphorus chloride oxidation reaction loop, avoiding poly phosphoric acid is heated and decomposed to produce the hypertoxic the phosphorus oxide is flue gas.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.22990-19-8, you can also check out more blogs about22990-19-8
