n-Pentane

Cyclopentane

Formula C5H12 C5H10
CAS # 109-66-0 287-92-3
Boiling Point, F/C 97/36 120/49
Vapor Thermal Conductivity, BTU/hr.ftF, 77 F 0.0076 0.0060
Vapor Thermal Conductivity, kcal/mhC, gas 0.0104*
Flash Point, F/C -58/-50 -44/-42
Explosive limits in Air, % by Volume 1.4-7.8 1.4-8
* HCFC-141b 0.0079, CFC-11 0.0072  for comparison, Fluorocarbons are generally superior in thermal conductivity, this superior behavior deteriorates as air diffuses into the foam structure.
