DOCUMENT TYPE: Report CA Section: 59 (Air Pollution and Industrial Hygiene) Environmental air samples were collected to det. the workers' exposure to acrolein [107-02-8], NH3 aniline [62-53-3], benzene [71-43-2], CO, dimethylamine [124-40-3], ethylamine [75-04-7], HCHO [50-00-0], HCN, methylamine [74-89-5] diphenylmethanediisocyanate [101-68-8], PhOH [108-95-2], 4-phenyl propylpyridine pyridine [110-86-1], PhMe [108-88-3], Et3N [121-44-8] and xylene [1330-20-7]. A pre- and post-shift medical questionnaire was administered to the workers in the molding and pouring departments. Exposures to pyridine and 4-phenyl propylpyridine [2057-49-0] (2-day av. concns.) in the molding area were 5.9 and 1.1 ppm, resp., with a combined av. exposure of 7.0 ppm.

Pelletizing of powdered ore or metal. Yoshimori, Yutaro; Matsuzuka, Seishiro (Nippon Magnetic Dressing Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 61201740 A2 6 Sep 1986 Showa, 5 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: C22B001-244. APPLICATION: JP 85-41547 2 Mar 1985. DOCUMENT TYPE: Patent CA Section: 54 (Extractive Metallurgy) Powd. Fe ore or metal is pelletized with a small amt. of binder without high-temp. heating or using a pelletizer app. The powder is mixed with a phenolic resin, polycyanate, and 4-phenylpropylpyridine (I). The mixt. is charged into a vibrated mold frame, and then settled for 5-20 min. In an example, binder mixt. contg. Ap-P200, I, and Ap-M750 at ~0.4:0.1:0.5% dose for a powder mixt. contg. converter dust, Fe, and Fe ore yielded the pellets of 32-35 mm diam.Except for chemicals metioned above, 7439-89-6 and 2057-49-0 are also used. with a crush strength of 210-260 kg/pellet. .
