This page provides supplementary chemical data on isobutane. ... Vapor pressure of liquid. P in mm Hg: 1: 10: 40: 100: 400: 760: ... Vapor pressure of iso-butane.
Isobutane is the principal feedstock in alkylation units of refineries. Using isobutane, gasoline-grade "blendstocks" are generated with high branching for good combustion characteristics. Typical products created with isobutane are 2,4-dimethylpentane and especially 2,2,4-trimethylpentane. [7] Typical acid-catalyzed route to 2,4-dimethylpentane.

Pure forms of butane, especially isobutane, are used as refrigerants and have largely replaced the ozone-layer-depleting halomethanes in refrigerators, freezers, and air conditioning systems. The operating pressure for butane is lower than operating pressures for halomethanes such as Freon-12 (R-12). Hence, R-12 systems, such as those in ...
Does anyone have a pressure/temperature chart or table for Butane? If so, could it be added to this page? Vapor pressure for n-Butane is 2.05 atm (NIOSH) National Institute for Occupational Safety and Health. (2005, Sept). NIOSH Pocket Guide to Chemical Hazards. pg 35. Publication No. 2005-149.
Values are given in terms of temperature necessary to reach the specified pressure. Valid results within the quoted ranges from most equations are included in the table for comparison. A conversion factor is included into the original first coefficients of the equations to provide the pressure in pascals (CR2: 5.006, SMI: -0.875).
Blood pressure is a crucial indicator of our overall health and well-being. Prolonged high blood pressure, or hypertension, can lead to severe complications such as heart disease, stroke, kidney ...
DePriester Charts provide an efficient method to find the vapor-liquid equilibrium ratios for different substances at different conditions of pressure and temperature. The original chart was put forth by C.L. DePriester in an article in Chemical Engineering Progress in 1953.
