PURPOSE: Novel azeotrope-like compositions of 1,1,1,3,3-pentafluoropropane and C1-C3 alcohols or mixtures thereof are useful in solvent cleaning. CONSTITUTION: An azeotrope-like composition consisting essentially from about 99.9 to about 80 weight percent 1,1,1,3,3-pentafluoropropane and about 0.1 to about 20 weight percent of an alcohol selected from the group of methanol, ethanol, n-propanol, isopropanol and mixtures thereof, wherein the composition has a boiling point at 760 mmHg of at least about 14.2°C to 14.5°C +- 0.5°C. 1,1,1,3,3-펜타플루오로프로판 및 C-C알코올 또는 이들의 혼합물의 신규한 공비혼합물 유사 조성물은 용매세척에 유용하다.
