A total of 19 VOCs were initially selected as the reference analytes for this study: (1) five aldehydes: acetaldehyde (AA), propionaldehyde (PA),butyraldehyde (BA), isovaleraldehyde (IA), and n-valeraldehyde (VA); (2) six aromatics: benzene (B), toluene (T), styrene (S), p-xylene (p-X), m-xylene (m-X), and o-xylene (o-X); (3) four carboxylic: propionic acid (PPA), butyric acid (BTA), isovaleric acid (IVA), and n-valeric acid (VLA); (4) two ketones: methyl ethyl ketone (MEK), and methyl isobutyl ketone (MIBK); (5) one alcohol: isobutyl alcohol (i-BuAl); and (6) one ester: n-butyl acetate (BuAc) (Table 2).
Products: Acetone derivatives, including isophorone, methyl isobutyl carbinol, and methyl isobutyl ketone
Miscellaneous metal parts and products surface coating operations emit a number of toxic air pollutants including xylenes, toluene, methyl ethyl ketone, methyl isobutyl ketone, phenol, ethyl benzene and glycol ethers.
Among these new PAQs, the polymer prepared from phenyl-p-benzoquinone and 2-butyl-2-ethyl-1,5-pentanediamine had demonstrated good solubility in common organic solvents such as acetone, methylene chloride, methanol, tetrahydrofuran, methyl isobutyl ketone, dimethylsulfoxide, and dimethylformamide.
However, whereas the organic solvent methyl isobutyl ketone readily extracts tantalum from solution, it fails to pull out hahnium.
Effective 15 April 2016 or as contracts allow, the new higher price for Methyl isobutyl ketone will be initiated in North and South America.
