Isopentane - Wikipedia
Isopentane, also called methylbutane or 2-methylbutane, is a branched-chain saturated hydrocarbon (an alkane) with five carbon atoms, with formula C 5 H 12 or CH(CH 3) 2 (C 2 H 5). Isopentane is a volatile and flammable liquid.
Question 74: For a unit targeting low vapor pressure gasoline, …
While the question asks specifically about isopentane production, other C5 hydrocarbons also have significant vapor pressure. Isopentane has a Reid Vapor Pressure (RVP) of 20 psi (pounds per square inch); n-pentane has an RVP of 16 psi; and, the …

Question 7: Given challenges in gasoline Reid vapor pressure (RVP ...
Some refiners are processing more C5 olefins in their alkylation units to reduce RVP in the pool. However, a fraction of the C5 olefins converts to isopentane via hydrogen transfer and cracking reactions, thus reducing some of the RVP benefit.

Methods and apparatus that are used in an alkylation reactor system for adding low purity isopentane to alkylation reactor feed to block formation of isopentane, resulting in high incremental...
(546b) Isopentane and Ethylene Alkylation Using Ionic Liquid
Historically, isopentane was a desirable blending component for gasoline having higher octane (92 RON), although it exhibited high volatility (20.4 Reid vapor pressure, RVP). As environmental laws began to place more stringent restrictions on gasoline volatility, the use of isopentane in gasoline was limited because of its high volatility.

Processing: RVP blending values listed for light HCs - ResearchGate
Oct 1, 2012 · A table that lists Rvp blending values for various hydrocarbons, e.g., ethane, propylene, propane, n-butane, and isopentane, is presented.
Isopentane - Air Liquide Gas Encyclopedia
Isopentane forms less than 1 % of natural gas. For many years, researchers, industrials and students spent a lot of time searching the information they needed on the molecules used in their plants and laboratories, in many publications.
INTRODUCTION. New restrictions on vaporization loss of petroleum products give added emphasis to the measurement of vapor pressure for petroleum fractions and their blends. The common method for measuring vapor pressure is the Reid vapor pressure (RVP) test.
