The mass spectrum also showed peaks at m/z 419 [CH2OH]+ and m/z 83 [C6H11]+ confirming that hydroxyl group is present at one end and cyclohexane
moiety at other end of the saturated chain.
, another derivative of benzene, is a basic raw material for the production of nylon, which is used to manufacture textiles.
According to a Reuters report, as part of the deal, Motiva will acquire a chemical plant owned by Flint Hills Resources that produces ethylene, cyclohexane
, and polymer grade propylene, located near its oil refinery in Port Arthur, Texas.
* Dichoromethane was detectable in 7 products (3.8-13.1 ppm) and cyclohexane
was found in one product (27.9 ppm).
Grant added: "During January 2017 the company closed its Aromatics (Benzene) and Cyclohexane
N-hexane (Fisher Scientific) or cyclohexane
(Sigma Aldrich) was used as polymerization medium and sodium persulfate ([Na.sub.2][S.sub.2][O.sub.8]) or potassium persulfate ([K.sub.2][S.sub.2][O.sub.8]) (Sigma Aldrich) was used as an initiator.
Analytical grade solvents like dichloromethane, methanol, chloroform, cyclohexane
and ethanol (Merck; B.P.) were used in this experiment.
The kinetic mechanisms of cyclopentane and cyclohexane
have been studied the most out of all the cycloalkanes due to their simplicity.
The optimal detection system is 2,2-dimethoxypropane as titrant, cyclohexane
, and isopropanol as titration solvents and methanesulfonic acid as catalyst.
We analyzed its molecular composition and compared the result with that of three other laboratories to confirm that it mainly contains 24 types of hydrocarbons: methane, ethane, propane, isobutane, M-butane, neopentane, isopentane, M-pentane, methyl cyclopentane, cyclohexane
, 2-methylpentane, 3-methylpentane, M-hexane, 2,2/3,3-dimethyl pentane, methyl cyclohexane
, 2/3-methyl hexane, 2,3-dimethyl pentane, M-heptane, benzene, M-octane, methyl benzene, M-nonane, ethylbenzene,p-xylene, and o-xylene.
Hexane, tetrahydrofuran, chloroform, and cyclohexane
were obtained from Merck (Darmstadt, Germany).
