Production of 1,6-hexane diol for use in polyester or polyurethane production involves reacting formaldehyde with propene to form a homo-allyl alcohol, catalytic metathesis to 3-hexene-1,6-diol and catalytic hydrogenation

摘要

Production of 1,6-hexane diols involves: (i) reacting formaldehyde with propenes (optionally substituted in the 2-position with alkyl or aryl) to give corresponding homo-allyl alcohols, (ii) metathesis in presence of a metathesis catalyst to give 3-hexene-1,6-diols and (iii) catalytic hydrogenation.
