This equation accounts for: (1) the higher reactivity of the ferrous sulphate ion pair relative to the free ferrous ion; (2) the catalysis of the reaction by copper; and (3) the activation energy of the reaction: −d[ Fe(II)] dt=(3.6×10 −5[ Fe 2+] 2P O 2+5.2×10 −4...
Complexes of general formula [MII(NH2C2H4NH2)3][B(C6F5)4]2 (1-6), where (M= Mn, Fe, Co, Ni, Cu, Zn) have been used as anti-microbial agents as well as catalysts for the cyclopropanation reaction with different olefins. They showed both excellent yields as catalysts, and very promis...

Heavy metals specified are iron, cobalt, nickel, and copper, a ferrous sulphate/sodium pyrophosphate complex being specified as a suitable salt. Monomers specified are 1,3-butadiene, 2,3 - dimethyl - 1,3 - butadiene, isoprene, piperylene, 3 - furyl - 1,3 - butadiene, 3 - methoxy - 1...
A broad spectral feature observed for ferrous ion in the 12,000–9000 cm−1 region both in scholzite and parascholzite. Some what similarities in the vibrational spectra of the three phosphate minerals are observed particularly in the OH stretching region. The observation of strong band...
The synthetic and natural yukonites were found to have a range of composition according to the general formula Ca2Fe3–5(AsO4)3(OH)4–10·xH2O where x = 2–11. The synthetic yukonite was found to be equivalent at the atomic, molecular and structural level to the Tagish Lake yukonite....
