Conversion of indole to oxindole under methanogenic conditions: Conversion of indole to oxindole under methanogenic conditions. Berry, D. F.; Madsen, E. L.; Bollag, J. M. (Dep. Agron., Pennsylvania State Univ., University Park, PA 16802, USA). Appl. Environ. Microbiol., 53(1), 180-2 (English) 1987. CODEN: AEMIDF. ISSN: 0099-2240. DOCUMENT TYPE: Journal CA Section: 60 (Waste Treatment and Disposal) Section cross-reference(s): 10 When indole [120-72-9] was incubated under methanogenic conditions with an inoculum of sewage sludge, the chem. was metabolized within 10 days and temporary formation of an intermediate was obsd. The metabolite isolated by thin-layer chromatog. was 1,3-dihydro-2H-indol-2-one (oxindole) [59-48-3]. The CH4 [74-82-8] produced (net amt.) indicated nearly complete mineralization of indole.

Monolithic refractories for hot working: Monolithic refractories for hot working. (Nippon Steel Corp.; Kyushu Refractories Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 60016875 A2 28 Jan 1985 Showa, 8 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: C04B035-66. ICS: C04B035-00. APPLICATION: JP 83-125873 11 Jul 1983. DOCUMENT TYPE: Patent CA Section: 57 (Ceramics) Phosphoric acid or phosphate 0.5-10 and lactam 0.2-6 are added to refractories 100 parts to give the monolithic refractories. The lactam ring in a heated aq. soln. is opened to react with phosphoric acid or phosphate and form a chelating compd. having reaction ability at low temp., and maintain sufficient fluidity of the refractories even at low water content region. The refractories are useful as hot spraying materials and hot lining materials for converters and refining ladles. Thus, 100 parts of magnesia clinker contg. MgO 96.1, CaO 1.0, Al2O3 0.1 SiO2 2.4, and Fe2O3 0.1 wt.% was mixed with Na hexametaphosphate 3, Ca pyrophosphate 1, slaked lime 2.5, and oxindole [59-48-3] 0.3 part to give a spraying material. The material was sprayed on a gas furnace at 1300° lined with converter dolomite bricks, and the sprayed material showed a high adherence rate, low porosity, and high d. and significantly high compressive strength.
