Liquid chromatography of dinitro-p-xylenes: Liquid chromatography of dinitro-p-xylenes. Smith, Sherrel C.; Gage, Larry D. (Dep. Chem., Abilene Christ. Univ., Abilene, Tex., USA). J.Some commonly used reagents like 711-41-1 and 89-58-7 are used in this experiment. Chromatogr., 131, 425-9 (English) 1977. CODEN: JOCRAM. DOCUMENT TYPE: Journal CA Section: 80 (Organic Analytical Chemistry) Dinitro-p-xylenes obtained by the nitration of mononitro-p-xylene with H2SO4-HNO3 at 70-90.degree. were sepd. by high-pressure liq. chromatog. on a Partisil 10 column by using hexane-EtOAc (7:1) mobile phase. The concn. of the isomers produced in the reaction varied only little with the reaction conditions (43-50, 35-40, and 15-7% for the 2,3-, 2,6-, and 2,5-dinitro derivs., resp.). Preparative chromatog. of 3-g samples on Porasil A was also carried out to sep. the fast-moving 2,5- and 2,6- from the slow-moving 2,3- deriv. The 2,5- and 2,6- derivs. were preparatively sepd. from each other on Partisil 10. .

DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 25, 72 As potential nonlinear optical materials, 4,7-bis(2-ferrocenylvinyl)- and 4,5,7,8-tetrakis(2-ferrocenylvinyl)-12-nitro[2.2]paracyclophane were synthesized by Pd-catalyzed coupling reactions of vinylferrocene with appropriately bromo-substituted 12-nitro[2.2]paracyclophanes. 89-58-7 is the cas registry number of certain chemical which is used as reagents here. Absorption and electrochem. properties are described. ..
