  • Patent number: 4772732
    Abstract: The invention discloses a method for purifying butylene oxide by using an anion exchange resin and an adsorbent. The anion exchange resin removes acid and aldehyde impurities while the adsorbent removes water impurities from the butylene oxide. Depending upon the impurity level, the purification steps can be conducted singularly or in combination, and the process can proceed either batchwise in a reactor or continuously in a column. The ion exchange resin of the choice is a sulfonated macroreticular anion exchange resin and the adsorbent of choice is a molecular sieve.

  • Patent number: 4764628
    Abstract: Asymmetric epoxidation of allylic alcohols using carboxylic acid treated phenethyl hydroperoxide oxidate and titanium tartrate catalyst gave optically active glycidols following an enantioselection rule opposite to that observed from the Sharpless epoxidation (U.S. Pat. No. 4,471,130). Overall yield and enantiomeric excess of the glycidol made are dependent on the amount of carboxylic acid present in the oxidate feed. This novel finding provides a direct epoxidation route to (R)-glycidol using the less expensive natural L-(+)-dialkyl tartrate ligand.
