Synthesis of ethylene glycol from syngas: Synthesis of ethylene glycol from syngas. I. A study on the catalytic carbonylation of butyl nitrite. Lee, Tae Jin; Han, Do Hung; Chae, Hee Kwon; Uhm, Sung Jin (Dep. Chem. Eng., Yeungnam Univ., Gyongsan 632, S. Korea). Hwahak Konghak, 24(4), 305-10 (Korean) 1986. CODEN: HHKHAT. ISSN: 0304-128X. DOCUMENT TYPE: Journal CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 23 The carbonylation of BuNO2 [544-16-1] to BuO2CCO2Bu [2050-60-4] was studied in the presence of 5% Pd/C, Pt/C, Ru/C, and Rh/C. The Pd catalyst gave the best results. The optimum reaction conditions were 60-70°, >900 psi, catalyst/reactant ratio 10-2, and reaction time <10 h. Catalyst deactivation was ascribed to N oxide formation during the reaction. Stirring speed and BuOH addn. did not affect the reaction.

Acute inhalation toxicity of aliphatic (C1-C5) nitrites in rats: Acute inhalation toxicity of aliphatic (C1-C5) nitrites in rats. Klonne, Dennis R.; Ulrich, Charles E.; Weissmann, John; Morgan, Andrew K. (Internat. Res. Dev. Corp., Mattawan, MI 49071, USA). Fundam. Appl. Toxicol., 8(1), 101-6 (English) 1987. CODEN: FAATDF. ISSN: 0272-0590. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) The 4-h inhalation median lethal concn. (LC50) values were detd. for Me [624-91-9], Et [109-95-5], Pr [543-67-9], Bu [544-16-1], iso-Bu [542-56-3], and isopentyl nitrite [110-46-3] in rats. LC50 values were 176, 160, 300, 420, 777, and 716 ppm, resp. The dose-mortality curves were characterized by extremely steep slopes. Toxic signs obsd. during exposure included cyanosis, prostration, and rarely, convulsions. There were no effects of exposure on body wt. 109-95-5 and 542-56-3 which are cas registry numbers of chemicals are mentioned. gain during a 14-day postexposure observation period. Signs of pulmonary hemorrhage were apparent in rats which died during exposure but were much less prominent in rats sacrificed at study termination. No animals died after cessation of exposure, and rapid recovery was apparent after exposure. Concn. ′ time (CT) relations suggested that the actual concn. was more important than the dose in detg. the lethal effects of inhalation exposure to nitrites. Because of the extremely steep dose-mortality curves, the aliph. nitrites are more hazardous than the LC50 values would indicate. .
