Cotton-Mouton constants and conformation of 2,2'- and 4,4'-dipyridyls and their salts in solutions: Cotton-Mouton constants and conformation of 2,2'- and 4,4'-dipyridyls and their salts in solutions. Timosheva, A. P.; Kushnikovskii, I. A.; Vul'fson, S. G.; Vereshchagin, A. N. (Inst. Org. Fiz. Khim. im. Arbuzova, Kazan, USSR). 85-00-7 and 2895-98-9 which are cas registry numbers are also used here. Izv. Akad. Nauk SSSR, Ser. Khim., (12), 2771-5 (Russian) 1991. CODEN: IASKA6. ISSN: 0002-3353. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The Cotton-Mouton consts. of 2,2'- and 4,4'-bipyridine and their salts, i.e., I (R = H, X = Cl; R = Me, X = I), II (same R, X), 4,4'-bipyridine monohydrochloride, and III (same R, X), were detd. in H2O. Protonation of the bipyridine did not affect the rotation angles of the rings, but methylation increased the acoplanarity. .

DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic Processes) The presence of a bipyridinium salt (1 .times. 10-5-1 .times. 10-2 mol/L), which may have the form of a 3-ring system, in a high-contrast developer of the hydroquinone-type accelerates its action and allows the use of .ltoreq.5-30 g SO32- without loss of contrast. 2895-98-9 and 54326-42-0 which are cas registry numbers of substances are two of reagents here. Thus, a stable developer contained (per L) hydroquinone 18, Na2CO3.1 H2O 60, Na2SO3 30, NaBr 3 g, and I 100 mg. Correction of CA 82: 49850j. .
