DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 27 A catalyst with improved activity, selectivity, and reproducibility for the vapor-phase oxidn. of furfural [98-01-1] to maleic anhydride [108-31-6] contained 1.4-2.8:1 MoO3-V2O5 mixt. and a P oxide in a molar ratio on a low-porous support, and was promoted with Co, Ce, In, Te salts, Te oxides, or In2(SO4)3 [13464-82-9], which are sol. in HCl.

Photoconductive cadmium sulfide

Photoconductive cadmium sulfide. (Canon K. K., Japan). Jpn. Kokai Tokkyo Koho JP 58069722 A2 26 Apr 1983 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C01G011-02; C01G015-00; G03G005-08. ICA: C30B009-12; C30B029-50. APPLICATION: JP 81-168088 21 Oct 1981. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) CdS contg. Cu and In 0.5 ′ 10-4 mols/mol each (both as sulfates) was mixed with CdCl2 80 and NaCl 120 g as flux (320%), heated at 530° (350° higher than m.p. of flux) for 30 min in a covered quartz crucible, washed, heated again at 450° for 1 h, washed, and deionized until cond. of washing was <1.0 m S/cm, and dried at 70° for 24 h. It was of 100% hexagonal 2.0-5.0 m size. When its 40 m photosensitive film on an Al plate was prepd., coated with a 25 m thick polyester layer, and copies were produced after leaving for 12 h in the dark, the dark potentials were 440 at 1st and 450 V at the 50th, and the sensitivity was 1.9 1x-s vs. 420 and 410 V and 2.8 1x-s, resp. 7440-74-6 and 13464-82-9 are just another two chemicals used in this study. without In. .
