To determine the type of isomers that n-pentane, iso-pentane, and neo-pentane represent, we can follow these steps:Step 1: Understand the Structures - n-Pentane: This is a straight-chain alkane with five carbon
An investigation was made of the effect of space velocity on the dehydrogenation of n-pentane and isopentane at 500–575° in presence of an alumina-chromium-potassium catalyst. The higher the temperature, the less the yields of monoolefins depend on space velocity. For reaction at 550° and ...

2023, Separation and Purification Technology Citation Excerpt : The pore diameter of isopentane is higher than the pore diameter of ZIF-8, so the adsorption resistance for isopentane is high enough. Although n-pentane kinetic diameter is higher than ZIF-8 pore diameter but the mIm linker of ZIF...
Pentane and water are then added and the organic phase is separated off, washed with water, dried over sodium sulfate, filtered and concentrated by evaporation, yielding 8a (1.30 g, 79%) in the form of a yellow oil which crystallises under HV: 31P-NMR (124 MHz, CDCl3): −12.4; 1H...
Other blowing agents, especially air, nitrogen, carbon dioxide, alkanes, alkenes, ethers may be used as the minor physical blowing agent. Representative alkanes include n-butane, n-pentane, isopentane, cyclopentane and mixtures thereof. Representative alkenes include 1-pentene. Representative ethers incl...
Neopentane burns most intensely, followed by isopentane, and finally n -pentane. A faster heating rate will be accompanied by more intense spontaneous combustion of n -pentane and more product formation, which will cause greater harm to the surrounding area. Thus, in order to reduce the ...
