TL;DR: In this article, lead is extracted from urine with ammonium pyrrolidien dithiocrbamate into methyl isobutyl ketone, and 20 μl of the extract is injected into a water carrier stream in a flow-injection/atomic absorption system.

TL;DR: In this paper, a new, rapid, relatively simple procedure for separating tin isotopes from all the other fission products has been developed, based on extraction of tin (II) into methyl isobutyl ketone from an aqueous sulphuric acid-potassium iodide solution and back-extraction of tin(IV) under the same conditions.

TL;DR: In this article, the catalytic oxidation of methyl isobutyl ketone (MIBK) and o -xylene was studied on different catalysts and the oscillations in the molar flow rate of CO 2 were observed in some systems, corresponding to apparent conversions into CO 2 exceeding 100%.

TL;DR: In this article, equilibrium and kinetic experiments on the recovery of nicotinic acid (0.02-0.10 kmol·m−3) were performed using tri-n-octylamine (TOA; 0.115 −0.459 kmol ·m-3) dissolved in methyl isobutyl ketone (MIBK) as a diluent.
Abstract: The design of an extraction process requires equilibrium and kinetic data for the acid (solute)–amine (solvent) system used. In this study, equilibrium and kinetic experiments on the recovery of nicotinic acid (0.02–0.10 kmol·m–3) were performed using tri-n-octylamine (TOA; 0.115–0.459 kmol·m–3) dissolved in methyl isobutyl ketone (MIBK) as a diluent. The chemical equilibrium of acid and amine is interpreted as a result of the formation of both 1:1 and 2:1 complexes with an equilibrium constant (KE) of 37.11 (kmol·m–3)−1.21. The mass-transfer coefficient (kL = 2.03 × 10–5 m·s–1) of nicotinic acid in MIBK was determined in a stirred cell. Based on the values of Hatta number (0.089–0.123) and the criterion proposed by Doraiswamy and Sharma (Heterogeneous Reactions: Analysis, Examples, and Reactor Design; John Wiley & Sons: New York, 1984), the reaction was found to be a very slow chemical reaction occurring in the bulk of the organic phase. The reaction was found to have orders of 0.8 with respect to nicoti...
