NOVELTY - An azeotrope-like composition (c1) comprises trans-1,3,3,3-pentafluoropropane (transHFO-1234ze), and a compound selected from propane, n-butane, isobutane, and/or 2-methylbutane.    USE - In a refrigerant, or refrigeration system such as automotive air conditioning systems, residential air conditioning systems, commercial air conditioning systems, residential refrigerator systems, residential freezer systems, commercial refrigerator systems, commercial freezer systems, chiller air conditioning systems, chiller refrigeration systems, heat pump systems; in blowing agent; in a doamable composition for forming foam or closed cell foam; and heating, cooling and sterilizing articles (claimed).    ADVANTAGE - The azeotropic composition has low global warming potential, and exhibits relatively constant boiling point and vapor pressure characteristics.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a composition (c2) comprising the composition (c1) and at least one adjuvant selected from supplemental lubricants, compatibilizers, surfactants, supplemental flame suppressants, solubilizing agents, dispersing agents, cell stabilizers, cosmetics, polishing agents, medicaments, cleaners, fire retarding agents, colorants, chemical sterilants, stabilizers, polyols, and/or polyol premix components;    (2) a heat transfer composition (c3) comprising the composition (c2) where the adjuvant is at least one lubricant;    (3) a heat transfer composition (c4) comprising the azeotrope-like composition (c1);    (4) a blowing agent comprising the azeotrope-like composition (c1);    (5) a foamable composition comprising at least one components capable of forming foam, and the azeotrope-like composition (c1);    (6) replacing an existing refrigerant contained in a refrigerant system involving removing at least a portion of the existing refrigerant from the system and replacing at least a portion of the existing refrigerant by introducing into the system the refrigerant composition;    (7) a sprayable composition comprising a material to be sprayed and a propellant comprising the azeotrope-like composition (c1);    (8) sterilizing an article involving contacting the article with a composition comprising the composition (c1);    (9) cooling an article involving condensing the composition (c1) and then evaporating the composition in the vicinity of the article to be cooled;    (10) heating an article involving condensing the composition (c1) in the vicinity of the article to be heated and then evaporating the composition; and    (11) a one-component foam or foamable composition comprising a foam forming agent and a blowing agent having the azeotrope-like composition (c1).
