To convert n-butane to isobutane, we can follow these steps:Step 1: Identify the Reactants - The starting material is n-butane, which has the molecular formula C4H10 and can be represented as CH3-CH2-CH2-CH3.Step
Then, the reactor was purged with nitrogen for 15 min prior to the introduction of n-butane. The reaction products were analyzed in a gas chromatograph with the thermal conductivity detector. Besides isobutane, which was the major product, methane, propane, and pentane were detected. After 1 h...

At 423 K and 2 MPa, the solubilities of butane and isobutane in PS were 0.08 and 0.05 g-gas/g-polym, respectively. Solubility could be correlated with the Sanchez-Lacombe equation of state with temperature-dependent binary interaction parameters to within 4.4% average relative deviation. Henry'...
n-butane and isobutane are important petrochemical raw materials. Their separation is challenging because of their similar properties, including boiling point. Here, we report a zeolitic imidazolate framework-8 (ZIF-8)/N,N-Dimethylpropyleneurea (DMPU)-water slurry as sorption material to separate but...
The transformation of an isobutane 2-butene mixture with a 40 weight ratio was carried out in liquid phase at 50 掳C on an USHY zeolite with a framework Si/Al ratio of 4.5. The reaction products can be classified into seven families: (a)... J Pater,F Cardona,C Canaff,... - 《In...
The viscosity of normal butane, isobutane and their mixtures The paper reports measurements of the viscosity of normal butane and isobutane at atmospheric pressure in the temperature range 25–195°C. In addition, the viscosity of mixtures of the two gases has been determined in the more limited...
