Method For Making Acrolein And Catalyst Therefor
US Patent:
4129600, Dec 12, 1978
Filed:
Mar 18, 1977
Appl. No.:
5/778907
Inventors:
David L. Childress - Angleton TX
William V. Hayes - Clute TX
Richard L. Poppe - Clute TX
William V. Hayes - Clute TX
Richard L. Poppe - Clute TX
Assignee:
The Dow Chemical Company - Midland MI
International Classification:
C07C 4720
C07C 4722
C07C 4722
US Classification:
260604R
Abstract:
A method of preparing acrolein and methacrolein by oxidation of propylene and isobutylene over a new improved catalyst providing conversions and yields, each greater than 90% in a single-pass reactor. The improved catalyst contains within certain prescribed proportions the oxides of cobalt, iron, bismuth, molybdenum, potassium, and optionally silicon. The metals have atomic ratios of Co. sub. 3-10 Fe. sub. 5-3. 0 Bi. sub. 5-3. 0 Mo. sub. 15 K. sub. 01-0. 5 Si. sub. 5-3. 0 and are present in the form of oxides as pellets, spheres, or on a support. With a recycle system, a conversion of the olefin greater than 99% and yield to the aldehyde of greater than 95% are possible.

Method For Making Acrylic Acid From Acrolein
US Patent:
4350830, Sep 21, 1982
Filed:
Oct 17, 1979
Appl. No.:
6/085568
Inventors:
David L. Childress - Angleton TX
William V. Hayes - Clute TX
Richard L. Poppe - Clute TX
William V. Hayes - Clute TX
Richard L. Poppe - Clute TX
Assignee:
The Dow Chemical Co. - Midland MI
International Classification:
C07C 5125
C07C 57055
C07C 57055
US Classification:
562535
Abstract:
A method for preparing acrylic acid by oxidation of acrolein over a new and improved catalyst providing conversions of acrolein of greater than 99% with yields of acrylic acid in excess of 95%. The catalyst consists essentially of the oxides of molybdenum, vanadium, chromium, copper and titanium and optionally silicon on an inert carrier. Catalysts useful in the process contain the elements previously mentioned in the atomic ratios of Mo. sub. 15 V. sub. 5-10 Cu. sub. 2-5 Cr. sub. 2-2 Ti. sub. 1-3.

US Classification:
252456
Abstract:
A method of preparing acrylic acid by oxidation of acrolein over a new and improved catalyst providing conversions of acrolein of greater than 99% with yields of acrylic acid in excess of 95%. The catalyst consists essentially of the oxides of molybdenum, vanadium, chromium and copper and at least one of tantalum and niobium and optionally silicon on an inert carrier. Catalysts useful in the process contain the elements previously mentioned in the atomic ratios of Mo. sub. 15 V. sub. 5-10 Cu. sub. 2-5 Cr. sub. 2-2 M. sub. 1-3 where M is tantalum, niobium or mixtures thereof.
