Objective:To determinate the contents of residual organic solvents:methanol,acetone,isobutanal,2-Methylbutylaldehyde,Methyl-iso-butyl ketone,benzaldehyde in α-Ketophenylalanine Calcium by Gas Chromatography.

MIBK is employed to extract the complex from aqueous solution,which separates Fe~(2+) from Fe~(3+) and reduces speciation transformation between the two oxidation states.

6 meanwhile Cr3+was hardly extracted when chromium in waste water was extracted by the mixing solvent extrations of MIBK and TBP on condition that PH was less than 1.

The ammonium pyrrolidinyldithiocarboxylate (APDC) was used as a chelate reagent, and then the Pb2+-APDC complex was extracted by methyl isobutyl ketone from an aqueous phase to an organic phase.

Iodine equi-volume extracted with methyl isobutyl ketone from aqueous solution,and then 20~40 μL of an organic solution containing iodine was injected into a pipette using a microsyringe,and the combine electrode was set just on the surface of the aqueous solution.

Slaking the sample of human hair by nitric acid and perchloric acid, then extracting trace cadmium from it by potassium iodide and methyl isobutyl ketone, then spraying the organic phase and mensurating the content of cadmium, and making a comparision between direct method standard addition method and atomic absorption spectrophotometry, the result showed that c.

Indirect determination of trace phosphorus in steel by flame atomic absorption spectrometric determination of molybdenum after extraction of heterphosphomolybdic acid with methyl isobutyl ketone;

Preparation of methyl isobutyl carbinol(MIBC)was studied by catalytic hydrogenation of methyl isobutyl ketone(MIBK)in liquid phase on Raney nickel catalyst.

The nano ferric oxide powder was prepared by using methyl isobutyl ketone as extractant.

Effects of MIBK on ICP Emission Spectral Analysis;

An extraction process of the phenol hydroxylation mixture with MIBK and DIPE as extraction solvents,and at different solvent-solute ratios was studied.

The distribution coefficients of MIBK to phenol and polyhydric phenols are greater than those of DIPE.

The extraction for separation of m-phenylenediamine, m-aminophenol and resorcinol was carried out with n-butanol(BuOH) , n-butyl acetate(BuAc) and 4-methyl-2-pentanone(MIBK) as extractant under different acid and alkali conditions.

The liquid-liquid phase equilibrium system in the dehydration of the phenol hydroxylation at 20℃ was studied,the extractants were isopropyl ether and 4-methyl-2-pentanone.
