Definitions

  • the present invention relates to the field of chlorofluorinated hydrocarbons and more particularly relates to a new composition having an azeotrope and usable as an agent for cleaning and degreasing solid surfaces, in particular in defluxing and cold cleaning of printed circuits.
  • 1,1,2-Trichloro-1,2,2-trifluoroethane (known in the art under the designation F113) is widely used in the industry for cleaning and degreasing solid surfaces.
  • F113 1,1,2-Trichloro-1,2,2-trifluoroethane
  • F113 1,1,2-Trichloro-1,2,2-trifluoroethane
  • F113 is most often combined with other organic solvents (for example methanol), preferably in the form of azeotropic or pseudo-azeotropic mixtures which do not demix and which, when used at reflux, have substantially the same composition in the vapor phase as in the liquid phase.
  • organic solvents for example methanol
  • F113 is one of the fully halogenated chlorofluorocarbons that are currently suspected of attacking or degrading stratospheric ozone.
  • the present invention proposes to replace the compositions based on F113 with a new composition based on methyl formate and 1,1-dichloro-1-fluoroethane.
  • the latter compound known in the art under the designation F141b, is practically devoid of destructive effect with respect to ozone.
  • the composition to be used according to the invention comprises from 55 to 80% by weight of F141b and from 20 to 45% of methyl formate.
  • F141b azeotrope whose boiling point is 28.4 ° C at normal atmospheric pressure (1.013 bar) and the composition according to the invention has a pseudo-azeotropic behavior, that is to say that the composition of the vapor and liquid phases is substantially the same, which is particularly advantageous for the intended applications.
  • the content of F141b is chosen between 61 and 65% by weight and that of methyl formate between 35 and 39% by weight.
  • the azeotrope F141b / methyl formate is a positive azeotrope since its boiling point (28.4 ° C) is lower than that of the two constituents (F141b: 32 ° C; methyl formate: 31.7 ° C).
  • the composition according to the invention can be advantageously stabilized against hydrolysis and / or free radical attacks likely to occur in the cleaning processes, by adding to it a usual stabilizer such as, for example , nitromethane, propylene oxide or a mixture of these compounds, the proportion of stabilizer possibly ranging from 0.01 to 5% relative to the total weight: F141b - methyl formate.
  • a usual stabilizer such as, for example , nitromethane, propylene oxide or a mixture of these compounds, the proportion of stabilizer possibly ranging from 0.01 to 5% relative to the total weight: F141b - methyl formate.
  • composition according to the invention can be used in the same applications and according to the same techniques as the previous compositions based on F113.
  • This azeotrope used for cleaning solder flux or degreasing mechanical parts, gives as good results as compositions based on F113 and methanol.
  • Example 3 is repeated using 0.1% nitromethane and 0.1% propylene oxide. The following results are obtained:
