Abbreviations: Iso propyl alcohol (IPA), methyl ethyl ketone (MEK), methyl isobutyl ketone
(MIBK), n-propyl alcohol (n-PA), ethyl acetate (EA), n-butanol, n-propyl acetate (n-PAc), ortho-xylene (xylene).
In a 50 mL round-bottom flask, 0.10 g (0.21 mmol) of 1 was partially solubilized in 10 mL of methyl isobutyl ketone
with stirring and slight heating (40[degrees]C).
With the exception of the YI site, styrene and methyl isobutyl ketone
were found at detection frequencies below 30% and 9%, respectively, at all other sites.
The Saudi team used the technology to obtain Methyl Isobutyl Ketone
(MIBK), whose applications are used in industrial, medical and petroleum fields.
Key statement: The present invention relates to a rubber composition containing a diene based elastomer reinforced with rubber reinforcing carbon black and/or silica which contains an antidegradant comprised of N-1,3-dimethyl-butyl-N'-phenyl-p-phenylene diamine (6-PPD) together with a dispersion of a methyl isobutyl ketone
(M1BK)-adsorbing activated carbon.
Solvents such as Toluene, Xylene, Methyl Isobutyl Ketone
, Methanol and Glycol Ethers are common examples of HAPs.
The nitrile work gloves offered pretty good chemical resistance, he said, but are subject to degradation and permeation by certain chemicals, such as methanol, methyl isobutyl ketone
, acetone, toluene, propyl acetate, trichloroethylene, and xylene.
