Catalyst resin
Provided is a plurality of resin beads, wherein the resin beads comprise polymerized units of monovinyl aromatic monomer and polymerized units of multivinyl aromatic monomer, and wherein the resin beads have BET surface area of 15 to 38 m 2 /g and volume capacity of 0.7 or higher. Also provided is a method of making a product of the chemical reaction of one or more reactants, where the method comprises reacting the reactants with each other in the presence of such resin beads.
1. A method of making a product of the chemical reaction of one or more reactants, said method comprising reacting said one or more reactants with each other in the presence of a plurality of resin beads, wherein said resin beads comprise
(i) 93.5% to 96% polymerized units of monovinyl aromatic monomer, by weight based on the weight of said resin beads,
(ii) 4% to 6.5% polymerized units of multivinyl aromatic monomer, by weight based on the weight of said resin beads,
wherein said resin beads have BET surface area of 15 to 38 m 2 /g and volume capacity of 0.7 or higher, wherein the chemical reaction is
