| titleOfInvention | Catalysts for Olefin Hydration and Method of Preparation |
| abstract | The present invention is directed to a polystyrene cation exchange resin catalyst for olefin hydration comprises: monomer units of (a) 7.5 to 11.5 wt % at least one polyvinylaromatic monomer and (b) 88.5 to 92.5 wt % at least one monovinylaromatic monomer; (c) 0.75 to 1.20 SO 3 H moiety on each aromatic ring of the polymer backbone; and (d) 0.70 to 1.20 halogen on each aromatic ring of the polymer backbone. The present invention also provides a method for preparing the catalyst including the steps of copolymerization, sulfonation, halogenation, and post treatment. Optimization of the copolymer crosslinking degree, sulfonation and halogenation extent enables the catalyst with a balance of catalysis activity and thermal stability. |
