Sulfonic acid cation-exchange resins in the synthesis of straight-chain alkylphenols

Kinetic characteristics of reactions occurring in the alkylation of phenol with straight-chain alkenes (C 9 , C 16 ) over the Amberlyst 15 Dry, Amberlyst 35 Dry, Amberlyst 36 Dry, Amberlyst 70, Amberlyst DT, Tulsion 66 MP, Lewatit K2640, Lewatit K 2431, and Relite EXC8D sulfonic acid cation-exchange...

Description
Summary:Kinetic characteristics of reactions occurring in the alkylation of phenol with straight-chain alkenes (C 9 , C 16 ) over the Amberlyst 15 Dry, Amberlyst 35 Dry, Amberlyst 36 Dry, Amberlyst 70, Amberlyst DT, Tulsion 66 MP, Lewatit K2640, Lewatit K 2431, and Relite EXC8D sulfonic acid cation-exchange resins have been determined experimentally. The activities of these catalysts in different types of reactions have been compared. The rate constants of all reactions decrease on passing from 1-nonene to straight-chain hexadecene. In the alkylations of phenol with straight-chain alkenes, the ortho -alkylphenol/ para -alkylphenol ratio is practically equal to the statistical ratio for all of the resins examined in their operation range.
