Ignition and thermal behavior of solid hydrazones. Jain, S. R. (Dep. Aeronaut. Eng., Indian Inst. Sci., Bangalore, India). Combust. Flame, 28(1), 101-3 (English) 1977. CODEN: CBFMAO. DOCUMENT TYPE: Journal CA Section: 50 (Propellants and Explosives) The results of DTA in air at 12.5. 588-68-1 and 6228-40-6 are cas registry numbers of chemicals which are used as reagents here.degree./min and of ignition delays with red fuming HNO3 (RFNA) contg. 10-12% NO2 are presented for benzophenone hydrazone [5350-57-2], tetraformaltrisazine [1743-13-1], benzalazine [588-68-1], furfuraldazine [5428-37-5], and phenylhydrazones of BzH, furfuraldehyde, HCHO, and benzophenone. All the phenylhydrazones and azines that are hypergolic with RFNA decomp. on heating, whereas benzalazine and benzophenone hydrazone, which boil without decompn., are nonhypergolic under identical exptl. conditions. .

Syntheses of some new polymeric crown ethers with cation-complexing and catalytic properties

Syntheses of some new polymeric crown ethers with cation-complexing and catalytic properties. Xu, Yuwu; Dong, Shihua; Bai, Xuduo; Wu, Hui (Dep. Chem., Wuhan Univ., Wuhan, Peop. Rep. China). Gaofenzi Tongxun, (4), 266-73 (Chinese) 1983. CODEN: KFTTAR. ISSN: 0453-2880. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 67 Polymeric crown ethers were prepd. by cyclization of poly(b-chloroethyl glycidyl ether) with disodium polyethylene glycol [H(OCH2CH2)nOH] (n = 1-4). The cation-complexing ability of these compds. with NaCNS and KCNS was investigated. 26746-34-9 and 35227-10-2 which are cas registry numbers of substances are two of reagents here. They were used as phase-transfer catalysts in Wolff-Kishner reactions, such as the formation of diphenylmethane [101-81-5] from diphenyl ketone hydrazone [5350-57-2], and in halogen exchange reactions, such as the transformation of C8H17Br [26746-34-9] to C8H17I [629-27-6] by KI or NaI. Their activities were comparable to those of dibenzo-18-crown-6 and 18-crown-6. .
