Definitions
- the subject of the invention is a cleaning composition based on halogenated hydrocarbons.
- 1,1,2-trichloro-1,2,2-trifluoroethane has been widely used in industry for the cleaning and degreasing of a wide variety of solid surfaces (metal parts, glasses, plastics, composites), for which an absence, or at the very least a residual content as low as possible, of impurities, in particular of organic nature, is required.
- F113 was particularly suitable for this purpose because of its non-aggressive nature with regard to the materials used.
- This product has been used in particular in the field of manufacturing printed circuits, to remove the residues of the substances used to improve the quality of the welds (referred to as the weld flux). This elimination operation is referred to in the art as "defluxing".
- F113 includes the degreasing of heavy metal parts and the cleaning of high-quality, high-precision mechanical parts, such as gyroscopes and military, aerospace and medical equipment. In its various applications, F113 is most often combined with other organic solvents (for example methanol), in order to improve its cleaning capacity.
- organic solvents for example methanol
- F113 is also used in the fields, especially in optics, for which it is required to have water-free surfaces, that is to say surfaces where water is only present in undetectable traces by the method of measurement (Karl Fisher method). F113 is for this purpose used in drying operations (or dewetting) of said surfaces, in combination with hydrophobic surfactants.
- F113-based compositions are now prohibited because F113 is one of the chlorofluorocarbons (CFCs) suspected of attacking or degrading stratospheric ozone.
- CFCs chlorofluorocarbons
- Various solutions have been proposed to provide a substitute for F113, but which does not present the problems of deterioration of the ozone layer or increase of the greenhouse effect.
- the greenhouse effect of a given product is quantified by its GWP (Global Warming Potential) which takes into account the intrinsic effect of radiation absorption by the molecule but also the lifetime of the molecule in the atmosphere. (or what amounts to the same of its concentration during a period of time considered, most often 1 century). This GWP is given in relation to CO2, taken as a reference gas.
- tDCE nonafluoromethoxybutane
- HFE7100 nonafluororomethoxybutane
- HFE7200 nonafluoroethoxybutane
- methylal and an alcohol an ether such as nonafluoromethoxybutane (HFE7100) or nonafluoroethoxybutane (HFE7200), as well as methylal and an alcohol.
- pentafluorobutane is described as 20 to 55%, preferably 25 to 50% by weight.
- trans-dichloroethylene is described as 40 to 70%, preferably 53 to 62% by weight.
- the amount of ether is described as less than 20%, preferably 5 to 15% by weight.
- the minimum amount of methylal and / or alcohol is not specifically mentioned, but the examples provide a about 1% by weight for methylal and about 1% by weight for alcohol (isopropanol).
- the compositions according to this document have the disadvantage of being flammable.
- WO-A-00/36046 generally describes mixtures of pentafluoropentane and fluorinated ether, optionally with an organic solvent.
- organic solvent chlorinated solvents such as trans-dichloroethylene can be used.
- the application WO-A-0056833 relates to cleaning compositions.
- This application describes mixtures pentafluorobutane, trans-dichloroethylene, and nonafluoromethoxybutane.
- the proposed amounts (in% by weight) are in particular 1-98 / 1-64 / 1-75.
- Examples of such compositions are a mixture containing, in% by weight, 35% pentafluorobutane, 64% trans-dichloroethylene and 1% nonafluoromethoxybutane.
- US20050267006 which is a continuation of the above application specifically claims quaternary mixtures pentafluorobutane, trans-dichloroethylene, nonafluoromethoxybutane and isopropanol.
- the invention thus provides a composition comprising: (i) 10 to 25% by weight of 1,1,1,3,3-pentafluorobutane;
- the composition according to the present invention comprises of (i) 16 to 24% by weight of 1,1,1,3,3-pentafluorobutane; (ii) 63 to 68% by weight of trans-dichloroethylene; (iii) 11 to 17% by weight nonafluoromethoxybutane and (iv) 2 to 4% by weight nonafluoroethoxybutane.
- the composition according to the present invention does not comprise alcohol or methylal.
- the invention further provides a composition consisting essentially of: (i) 10 to 25% by weight of 1,1,1,3,3-pentafluorobutane; (ii) 62 to 70% by weight of trans-dichloroethylene; and (iii) 10 to 21% by weight of nonafluoromethoxybutane and (iv) 1 to 4% by weight of nonafluoroethoxybutane.
- the composition comprises: (i) 16 to 24 wt.% 1,1,1,3,3-pentafluorobutane;
- the composition contains up to 1% by weight of compounds other than methylal or the alcohol, preferably up to 0.5% by weight and advantageously up to 0.1% by weight.
- the invention further relates to the use of the composition according to the invention as a cleaning agent, solvent, degreaser, defluxant or desiccant, preferably for the degreasing and / or precision cleaning of metal parts.
- the invention uses the combination of four compounds, preferably in the absence in particular of compounds such as methylal and especially an alcohol.
- the presence of an alcohol is required in several compositions according to the state of the art.
- the term "alcohol” used in the present invention is intended to include linear or branched alkanols having up to 6 carbon atoms, alkanols whose presence is preferably excluded in the present invention.
