A low-pressure reactor(LPR) was developed for the measurement of ambient organic peroxy(RO2)radicals with the use of the laser-induced fluorescence(LIF) instrument.The reactor converts all the RO_(x)(=RO2+HO2+RO+OH) r...
Low pressure column chromatography with activated charcoal powder was used to separate the oligosaccharides and their isomers from the hydrolysates of konjac glucomannan.
Metal clusters RCCo_3(CO)_9(R-H,C1,Br,CH_3,Ph) were prepared in 18.8-57.3% yields from the reaction of cobalt(Ⅱ)salt and RCX_a under mild PTC conditions(latm CO,25℃).The cobalt salt was reduced to Co(CO)_4 in the pr...
