Fundamentally, the dehydration reaction of tertiary-butanol is frequently used as an internal standard for relative rate studies of other decomposition reactions. A study is reported using radical trappers to isolate this path in tertiary-butanol pyrolysis experiments conducted in the Princeton variable pressure flow reactor between 658-980 K. A novel technique that determines the rate constant value by applying a global least-squares fit incorporating all exptl. species (tertiary-butanol, isobutene, and water) evolution data is developed and applied to yield six rate constant values at two reaction pressures (6.1 and 18 atm) and at temperatures between 949-980 K. Data from previously reported studies are reanalyzed to evaluate their absolute uncertainties, and new Arrhenius parameters are derived based upon the present and previous measurements. The recommended rate constant (uncertainties) for the dehydration reaction is k = 2.88(0.91) × 107T2.21(0.10) s-1 exp-(-62.4-(0.9) kcal mol-1/RT). The new correlation is in excellent agreement with other independent exptl. and theor. studies appearing in the literature. In addition to this study using 3-Chloro-4-fluorophenylacetonitrile, there are many other studies that have used 3-Chloro-4-fluorophenylacetonitrile(cas: 658-98-0Recommanded Product: 658-98-0) was used in this study.
3-Chloro-4-fluorophenylacetonitrile(cas: 658-98-0) belongs to nitriles. Nitriles are found in many useful compounds. Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons.Recommanded Product: 658-98-0
