TL;DR: In aqueous acid solutions, the complex [Ag(H2L)]3+ + = ethylenebis(biguanide) quantitatively oxidises ethanol, isopropyl alcohol, and benzyl alcohol to the corresponding carbonyl products at moderate rate.
Abstract: In aqueous acid solutions, the complex [Ag(H2L)]3+(H2L = ethylenebis(biguanide)] quantitatively oxidises ethanol, isopropyl alcohol, and benzyl alcohol to the corresponding carbonyl products at moderate rate. The experimental rate law is –d[complex]/dt=(k1+k2/[H+])[alcohol][complex]. At 40 °C and I= 1.0 mol dm–3, 105k1, (dm–3 mol–1 s–1) and 106k2(s–1) values are: EtOH, 4.2 ± 0.3 and 2.8 ± 0.1; PriOH, 7.5 ± 0.5 and 4.8 ± 0.2; PhCH2OH, 95 ± 6 and 32.5 ± 2 respectively. The upper limit for the rate of reaction of [Ag(H2L)]3+ with methanol, t-butyl alcohol, ethylene glycol, and glycerol is the rate of autodecomposition of [Ag(H2L)]3+ and is less than 10% of the rate of oxidation of EtOH, PriOH, or PhCH2OH. Deprotonation of the alcohols assisted by axial co-ordination to [Ag(H2L)]3+ is suggested as a source of the inverse acid dependence. The whole reaction course is e.s.r. silent and a rate-determining C–H bond cleavage in the –CHOH group appears reasonable. Compared to other metal-ion oxidants, [Ag(H2L)]3+ appears to be the most selective reagent for PhCH2OH.

TL;DR: In this paper, a method of improving luminous efficiency of a rare earth-doped up-conversion luminescence nanometer material through changing the usage of a ligand was proposed.
Abstract: The invention provides a method of improving luminous efficiency of a rare earth-doped up-conversion luminescence nanometer material through changing the usage of a ligand. According to the method, the synthesis adopts a hydrothermal-solvothermal method, an organic ligand is an organic compound such as monocarboxylic acid, dicarboxylic acid or polycarboxylic acid, and amine, the molar ratio of rare earth ions to the ligand is 2:1-1:100, the molar ratio of NaOH to the ligand is 0:1-1:1, water/alcohol, water/n-propanol alcohol, water/isopropyl alcohol, water/n-butyl alcohol, water/acetone or water/ethylene glycol is used as a solvent, the temperature ranges from 180-240 DEG C, the reaction time is 2-24h, and the F /Re value ranges from 4-12. With the method, the problems of selecting various ligands for synthesizing the up-conversion luminescence nanometer material, improving the luminous efficiency of the rare earth-doped up-conversion luminescence nanometer material, synthesizing the water-soluble up-conversion luminescence nanometer material, and the like can be mainly solved.

TL;DR: An improved method for the determination of volatile fatty acids in the blood plasma of ruminant animals is described, using a new methodology based on gas-liquid chromatography.
Abstract: An improved method for the determination of volatile fatty acids in the blood plasma of ruminant animals is described. The acids are extracted as their sodium salts with isopropyl alcohol and then dissolved in 9 + 1 diethyl ether-formic acid for determination by gas-liquid chromatography.
