The best known and most nsefnl of the chemiluminescent reactions involving electron transfer is the oxidation of luminol (3.100) or its derivatives in alkaline medium. The oxidant can be hydrogen peroxide, sodium ferricyanide or hypochlorite, usually with a catalyst that can be a transition metal ion, such as Cu " Co +, Fe + and Mtf+, or haem and haemproteins, e.g. peroxidases. The reaction mode is shown in Figure 3.22.4"...

In the early oxidation nitration preparation of DNPOH, the yield is relatively low (59-63 %), the product needs further purification, there is formaldehyde condensation reaction and other serious problems. Jeong et al. [63] modified the oxidation nitration process to optimize the oxidation nitration conditions of silver nitrate, in which aqueous formaldehyde solution (mass fraction of 35 %) was used for hy-droxymethylation and its reaction conditions were optimized, and a yellow solid DNPOH was obtained after extraction with methylene chloride and distillation. The average yield of DNPOH was more than 90 % and the mass fraction was more than 97 %. Based on these results, Grakauskas et al. [40-42, 65] used potassium ferri-cyanide as catalyst and potassium persulfate as oxidant to synthesize DNPOH. In this method, with potassium(sodium) ferricyanide and over potassium(sodium) persulfate, nitrite substitution reaction of nitroethane with sodium nitrite occurred, and then further reacted with formaldehyde under basic conditions, and finally DNPOH was extracted out with ethyl acetate under acidic conditions. Product was obtained through potassium distillation. The reaction mechanism is ...

Blood-brain barrier the barrier that must be crossed when water and solutes are exchanged between blood and extracellular fluid of the central nervous system. Many substances, when injected intravenously, become distributed throughout the various tissues and organs of the body, except for the central nervous system, e. g. acidic dyes, bile acids, tetanus toxin, sodium ferricyanide, trypan blue. 

For copper minerals, the prescriptions are mainly comprised of phosphoms compounds sulfides oxidizers such as KMn04, H2O2, and KCIO3 and cyanide-containing compounds such as sodium ferricyanide and sodium zinc cyanide. For secondary copper minerals, the prescriptions are mainly comprised of cyanide-containing compounds.
