Methods for the removal of ionic contaminants from a hydrophilic organic solvent by a mixed bed of ion exchange resins are described. A mixed bed of ion exchange resins with gel-type strong-acid cationic ion exchange resin with a specific moisture holding capacity and gel-type anionic ion exchange resin is used in some embodiments of such methods.

Purification process for hydrophilic organic solvent

Provided is a resin composition comprising Also provided is a method of processing an aqueous composition using such a composition.

Resin beads and inorganic particles

Methods for the removal of ionic contaminants from hydrolysable organic solvent by ion exchange resins are described. A mixed bed of ion exchange resin with cationic ion exchange resin and weak-base anionic ion exchange resin is used in such methods.

Purification process for hydrolysable organic solvent

This invention relates to no-salt and mixed salt suspension polymerization processes for water-soluble monomers and resins and relates to catalysts produced from the same.

Mixed salt suspension polymerization process and resins and catalysts produced thereof

A method of making a plurality of resin beads comprising (a) providing a reaction mixture comprising monovinyl aromatic monomer, multivinyl aromatic monomer, and porogen, (b) performing aqueous suspension polymerization on said reaction mixture to form resin beads, and (c) sulfonating said resin beads. Also provided is a plurality of resin beads, wherein said resin beads comprise polymerized units of monovinyl aromatic monomer and polymerized units of multivinyl aromatic monomer, wherein said resin beads have BET surface area of 15 to 38 m/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, said method comprising reacting said one or more reactants with each other in the presence of the plurality of such resin beads.

Catalyst resin
