Self-diffusion and trace component diffusion of chloride ion in particles of hydrous ceric oxide as a function of chloride ion capacity

Self-diffusion and trace component diffusion of chloride ion in particles of hydrous ceric oxide as a function of chloride ion capacity. Shabana, E. I.; El-Naggar, I. M.; El-Absy, M. A. (Nucl. Res. Cent., At. Energy Establ., Cairo, Egypt). J. Radioanal. Nucl. Chem., 157(2), 245-53 (English) 1992. CODEN: JRNCDM. ISSN: 0236-5731. DOCUMENT TYPE: Journal CA Section: 65 (General Physical Chemistry) Self-diffusion coeffs. for chloride ion were measured as a function of chloride ion capacity in solns. of varying acidity using particles of hydrous ceric oxide heated at 50, 200 and 400°. The measured self-diffusion coeffs. depend on the total chloride ion capacity. At the same capacity, self-diffusion coeffs. are almost the same for ceria particles heated at different temps. The trace-component diffusion coeffs. of chloride ion in the nitrate-form of the oxide, dried at 50°, were also measured. 16887-00-6 and 23322-64-7 are just another two chemicals used in this study. Under the same conditions, the self-diffusion coeffs. are somewhat higher or close to the trace component diffusion coeff. for the sample dried at 50°. .

Conversion of diphenyl ethers to dibenzofurans using catalysts containing ceria

Conversion of diphenyl ethers to dibenzofurans using catalysts containing ceria. Fishel, Norman A. (Monsanto Co., USA). U.S. US 4009185 22 Feb 1977, 6 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07D307-91. NCL: 260346200M. APPLICATION: US 75-603065 8 Aug 1975. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Dibenzofuran was manufd. with a selectivity of 92% by cyclizing Ph2O at 482.degree. 101-84-8 and 23322-64-7 are cas registry numbers of chemicals which are used as reagents here. with an hourly space velocity of 52 h-1 on a ceria catalyst. The catalyst was prepd. by oxidizing Ce(NO3)3 at 450.degree. for 5 h, pelleting with graphite powder, calcining at 600.degree. for 4 h, crushing to 10-16 mesh size, and was used in a fixed bed. 2,5-Dimethyldibenzofuran was similarly prepd. .
