Stable emulsions of water in 1,1,2-trichloro-1,2,2-trifluoroethane. Chabert, Pierre; Foulletier, Louis (Ugine Kuhlmann, Fr.). Ger. Offen. DE 2601601 22 Jul 1976, 11 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C11D003-43. PRIORITY: FR 75-1606 20 Jan 1975. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) Stable emulsions of water in Cl2FCCF2Cl (I) [76-13-1] are obtained for cleaning and corrosion protection of metals. The emulsions contain I 70-98.5, H2O 1-20, and surfactant 0.Several reagents with their cas registry numbers 61313-75-5 and 61253-11-0 are used here.5-10%. A compd. of a phosphoric ester of a C6-20 aliphatic alc. and 2 amines, one of which is sol. in H2O and the other in nonpolar solvents, serves as a surfactant. Thus, an emulsion was obtained by mixing (Me2CH)2NH [108-18-9]-tridecyl di-H phosphate [5116-94-9]-bis(tridecyl) H phosphate [5116-95-0] 80, 3-(oleylamino)propanamine [7173-62-8]-tridecyl di-H phosphate-bis(tridecyl) H phosphate 20, H2O 200 and I 700 g. By further diln. of this mixt. with I, emulsions contg. 8, 6, 4 and 2% H2O and 4, 3, 2 and 1%, resp., of the surfactant were obtained. These emulsions were stable from 20 to 45-46.degree., i.e. to the boiling temp. .
