PURPOSE:To obtain the title detergent which has performance comparable to that of F-113 detergent and does not cause ozonosphere destruction by incorporating a specified amount of at least one of an alcohol, a ketone, an ester, and a chlorohydrocarbon into a principal component comprising hexafluorobenzene. CONSTITUTION:A principal component comprising hexafluorobenzene is mixed with 3-50wt.% of at least one of an alcohol (e.g. methanol), a ketone (e.g. acetone), an ester (e.g. ethyl acetate), and chlorohydrocarbon (e.g. methylene chloride) to produce a detergent for flux. When this detergent is employed for removing a flux used in soldering electronic parts, there is no fear of causing ozonosphere destruction, etc., and also a flux can be removed as efficiently as in the case wherein 1,1,2-trichloro-1,2,2-trifluoroethane is used. |
