537-00-8 Usage
Uses
Cerium Acetate, is applied as an alternative material for auto catalyst manufacturing and also for some special polishing powder. In glass industry, it is considered to be the most efficient glass polishing agent for precision optical polishing. It is added to the dominant catalyst for the production of styrene from methylbenzene to improve styrene formation. It is used in FCC catalysts containing zeolites to provide both catalytic reactivity in the reactor and thermal stability in the regenerator.

Check Digit Verification of cas no
The CAS Registry Mumber 537-00-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 537-00:
(5*5)+(4*3)+(3*7)+(2*0)+(1*0)=58
58 % 10 = 8
So 537-00-8 is a valid CAS Registry Number.

Insights into the ceria-catalyzed ketonization reaction for biofuels applications
Snell, Ryan W.,Shanks, Brent H.
supporting information, p. 783 - 789 (2013/05/22)
The ketonization of small organic acids is a valuable reaction for biorenewable applications. Ceria has long been used as a catalyst for this reaction; however, under both liquid and vapor phase conditions, it was found that given the right temperature regime of about 150-300 °C, cerium oxide, which was previously believed to be a stable catalyst for ketonization, can undergo bulk transformations. This result, along with other literature reports, suggest that the long held belief of two separate reaction pathways for either bulk or surface ketonization reactions are not required to explain the interaction of cerium oxide with organic acids. X-ray photon spectroscopy, scanning electron microscopy, and temperature programmed decomposition results supported the formation of metal acetates and explained the occurrence of cerium reduction as well as the formation of cerium oxide/acetate whiskers. After thermogravimetry/mass spectrometry and FT-IR experiments, a single reaction sequence is proposed that can be applied to either surface or bulk reactions with ceria.
