The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6. In a Article，once mentioned of 14187-32-7, name: Dibenzo-18-crown-6
In 1967 Pedersen described dibenzo-18-crown-6 (1).We report the preparation of its isomeric dihydroxy derivatives 2c and 3c.Nitration of 1 in acetic acid and chloroform yields the dinitro compounds 2a and 3a. 2a and 3a have different solubility in ethylene glycol monomethyl ether and can be separated.Catalytic reduction of the dinitro derivatives with hydrazine and Raney nickel leads to the diamines 2b and 3b.The diazonium salts of 2b and 3b are heated in dilute sulfuric acid and yield the phenols 2c and 3c. – Key words: Dibenzo-18-crown-6, Isomeric Dihydroxy Derivatives
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.name: Dibenzo-18-crown-6, you can also check out more blogs about14187-32-7
