[Problem] To obtain a substrate cleaning solution capable of cleaning a substrate and removing particles. [Means for Solution] To provide a substrate cleaning solution comprising an insoluble or hardly soluble solute (A), a soluble solute (B), and a solvent (C), wherein the solvent (C) comprises water (C-1); and the content of the soluble solute (B) is 0.1 to 500 mass % based on water (C-1).

A method of making chlorofluorohydrocarbons including, contacting, a fluorinated hydrocarbon reagent in the vapor phase, with hydrogen chloride (HCl). The reaction is conducted in the presence of an effective amount of a catalyst, at an elevated temperature sufficient to effect hydrochlorination to form a reaction mixture including a chlorofluorohydrocarbon.

An azeotropic cleaning solvent composition has from about 96 to about 98 weight percent 1,1,1,3,3,3-hexafluoro-2-methoxypropane (“HFMOP”) and from about 2 to about 4 weight percent acetone, for example, about 97 weight percent HFMOP and about 3 weight percent acetone. Another composition of the invention has a weight ratio of HFMOP to acetone of about 24 to about 99, for example, about 24 to 49. Conventional additives such as surfactants, lubricants and co-solvents may be present in an amount not to exceed about 10 weight percent of the composition. A method of the invention comprises contacting an article of manufacture with the solvent composition in order to clean the article of manufacture and then removing the solvent composition from the article of manufacture.
