Isobutane is being seen more and more across the world. Any leak can either be liquid or vapor. Bull. [all data], Rossini, 1943 Then enter the temperature or pressure you are interested in and the calc will give the estimated pressure or temperature that boiling will take place. Uncertainty assigned by TRC = 0.15 K; measured while refluxing in glass colukmn, Cu-const. ; Maass, O., Data from NIST Standard Reference Database 69: The National Institute of Standards and Technology (NIST) The goal is to have every refrigerant out there listed with a pressure/temperature chart that is easily available.

Contact with the liquid can cause frostbite. Contact with the liquid can cause frostbite. and chemical property data is available from the Chances are, if you're an avid camper, or at the very least, enjoy the outdoors, you've seen your fair share of 16.4 oz propane tanks. But, these numbers won’t do you any good if you don’t know what refrigerant you are dealing with and what the refrigerant’s boiling point is at each pressure level. Data, 1996, 25, 1, 1, It is easily ignited. Boiling Point: Turning from Liquid to Gas Isobutane and butane have different boiling points — the temperature at which it goes from liquid to gas (vapour). This holds especially true as various countries begin to phase out the ever common HFC refrigerants such as R-404A and R-134a. Copyright for NIST Standard Reference Data is governed by [all data], Daubert, 1996 Pet. Isobutane is a colorless gas with a faint petroleum-like odor. I’ve seen it multiple times on various refrigerants. [all data], Das, Reed, et al., 1973 We do not directly sell any products or refrigerants, but rather provide information, knowledge, and explanations to the consumer.
