Contents on the CD Rom

  • Phenols are produced by the following routes:
    -from cumene (isopropylbenzene) by hydrolysis of its hydroperozide; byproduct is acetone;
    -from benzenesulfonic acid by fusion with NaOH, above 300oC, then acidification;
    -from chlorobenzene by high T, P reaction with NaOH, then acidification
    Laboratory Preparations ;
    -from the aryl diazonium salt by hydrolysis (water, 100oC); from the aniline, from the
    nitroaromatic.
     
  • Most phenol today is synthesized under an indirect three-step process (called the cumene method).
  •  Cumene per oxidation is the preferred route to phenol, accounting for more than 90% of world production.
  • The main use for phenol is to make Bispenol A for polycarbonate resins.
  • The world market for phenol is 10.7 million t/y. Japan, Korea, Taiwan and China consume about 35% and the US and Canada use about 30%. The largest use is for the automobile, consumer and electronics industries. The second largest use in the US is for phenolic resins for oriented strand board. Worldwide growth in phenol is forecast at 4.5% over the next 5 years mainly in China.
  • Phenol prices follow raw material costs and oil prices fairly closely.
  • Phenol is the second-largest
    commodity produced from the
    inexpensive raw material, benzene.
    Using the new technology to
    produce phenol directly will allow
    industry to accrue significant cost
    savings.
