These bad-smelling compounds were heptanal, octanal, nonanal of aldehydes, and five ketones: 3,3-dimethylcyclobutanone ([C.sub.6]-ketone), methyl isobutyl ketone
(MIK), 3, 4-dimethyl-2-hexanone ([C.sub.8]-ketone) and isopropylcyclohexanone and 4,6-dimethyl-5-hepten-2-one ([C.sub.9]ketones).
The third targeted area focused on eliminating the carrier and flush solvents methyl ethyl ketone (MEK), methyl isobutyl ketone
(MIBK), toluene and xylene -- all high-priority 33/50 chemicals -- from its paints.
They encompass widely used industrial compounds such as xylene, methyl ethyl ketone, 1,1,1-trichloroethane, 1,1,2-trichloroethane, methylene chloride, methanol, trichloroethylene, methyl isobutyl ketone
, perchloroethylene, toluene, ammonia, benzene, urethane, ethylene glycol, formaldehyde, naphthalene, phenol and carbon tetrachloride.
The potential advantage for a processor in converting paint systems to Unicarb is to reduce emissions of volatile organic compounds (VOCs) like the solvents hexane, xylene, toluene, benzene, methyl isobutyl ketone
(MIBK), and methyl ethyl ketone (MEK).

Relative standard deviations for the seven runs varied from less than 1.0% for m/p-xylene to about 30% for methyl isobutyl ketone
, benzene and acetone.
In North and South America, the company will increase the prices of MIBK (Methyl Isobutyl Ketone
) by USD0.05/lb and MIBC (Methyl Isobutyl Carbinol) by USD0.05/lb.
