secondary butyl alcohol, n-butene hydration |
| Remarks： |
R & D Background:
Methylethyl ketone (MEK) is an excellent organic solvent, which is widely used in synthetic resin (cellulose nitrate, vinyl resin, propenyl resin etc), rubber adhesive, magnetic type, printing ink, lube dewaxing, and etc. Secondary butyl alcohol is the only material for MEK production. Moreover, in China, the production of secondary butyl alcohol cannot meet the demand of market. The annual import these years is over 100,000 tons.
FRIPP started the process study for producing MEK through n-butene direct hydration and subsequent dehydrogenation. On the basis of the process study, DNM-type catalyst for butane hydration and FDH-type catalyst for secondary vinyl alcohol dehydrogenation have also been developed.
Features
*The hydration process uses low LHSV and high water/n-butene ratio, which results in low n-butene recycling and low energy cost.
*High yield for secondary vinyl alcohol and low organics content in discharging water, which decrease pollution to the environment.
*Dehydrogenation catalyst has long run length.
Summary:
Isopropanol (and its derivative acetone) and MEK are high value chemical materials that demand large quantities of import. As a high-octane gasoline blending component, secondary vinyl alcohol has great market potential. Therefore, hydration, being an efficient way for C3 and C4 utilization, will attract more and more attention in petrochemical industry. Besides the above-mentioned technologies, FRIPP has also developed the technology for synthesizing diphenylamine and subsequent products from aniline, technology for producing 1, 4-butanediol through etherification and hydrogenation of maleic anhydride. All these technologies, we are sure , will bring considerable economic benefits to enterprises.
