Definitions
- the present invention relates to hydrochlorofluoroolefin-based cleaning compositions and the use of these compositions for a cleaning process.
- CFC-13 1,1,2-Trichloro-1,2,2-trifluoroethane
- the CFC-1 13 was particularly suitable for this purpose because of its non-aggressive nature with regard to the materials used.
- this product has been used in the field of printed circuit manufacturing, to remove residues of substances used to improve the quality of solder (referred to as solder flux). This removal operation is referred to in the art as "defluxing".
- US 2006/0142173 and US 2009/0318323 disclose the use of various fluoro-olefins as a cleaning agent, including 1-chloro-3,3,3-trifluoropropene (HFCO-1233zd).
- HFCO-1233zd 1-chloro-3,3,3-trifluoropropene
- WO 2009/140231 also describes the use of HFCO-
- HFCO-1233zd for the cleaning of solid surfaces, and particularly for defluxing.
- the document also mentions the possibility of using a certain number of co-agents chosen from a list which notably comprises 1,2-transdichlorethylene (TDCE).
- TDCE 1,2-transdichlorethylene
- the only example of a cleaning composition comprising HFCO-1233zd and TDCE which is mentioned in the document is a ternary mixture, the third compound being methylacetate.
- WO 2009/08951 1 very broadly describes compositions based on fluorolefins and their use in a wide variety of fields, including cleaning.
- HFCO-1233zd is one of the described fluoroolefins.
- the document evokes the possibility of combining HFCO-1233zd with TDCE (in particular in 25:75, 50:50 and 75:25 mass ratios) in different cleaning applications, namely in the field of blowing agents, silicone deposition (use as silicone oil solvent) and fragrance extraction.
- the document proposes to use HFCO-1233zd alone, or in combination with methanol.
- HFCO-1233zd is a relatively powerful compound for cleaning applications, and has the advantage of being environmentally friendly. In particular, it has a low GWP. However, the effectiveness of HFCO-1233zd for cleaning solid surfaces is still unsatisfactory, at least in some applications, and whether used alone or in ternary combination with TDCE and methylacetate.
- the invention relates firstly to the use of a liquid composition comprising 1-chloro-3,3,3-trifluoropropene and 1,2-transdichloroethylene for cleaning solid surfaces, 1-chloro-3,3 , 3-trifluoropropene and 1,2-transdichloroethylene representing at least 99% by weight of the composition.

- At least 80% by weight of 1-chloro-3,3,3-trifluoropropene in the liquid cleaning composition is in trans form, preferably at least 90% by weight, more preferably minus 95% by weight, advantageously at least 98% by weight, and ideally essentially all of 1-chloro-3,3,3-trifluoropropene is in trans form.
- the invention also relates to a liquid composition
- a liquid composition comprising 1-chloro-3,3,3-trifluoropropene and 1,2-transdichloroethylene, 1-chloro-3,3,3-trifluoropropene and 1,2-transdichloroethylene representing at least 99% by weight of the composition, and the weight ratio of 1-chloro-3,3,3-trifluoropropene to 1,2-transdichloroethylene is between 57:43 and 65:35, preferably between 58: 42 and 63:37, more preferably between 59:41 and 61:39.
- the liquid composition is as described in the preceding paragraph.
- the liquid cleaning composition is as described in the preceding paragraph.
- the present invention overcomes the disadvantages of the state of the art. It provides more particularly an improved cleaning process, based on the use of a cleaner performing better, especially vis-à-vis certain fats, and has interesting physicochemical properties (especially a low GWP).
- the invention also has one or preferably more of the advantageous features listed below.
- compositions according to the invention are more efficient than the HFCO-1233zd used alone or the HFCO-1233zd used in ternary mixture with TDCE and methylacetate, especially vis-à-vis mineral fats loaded with lithium / calcium (greases for resistance to high pressures) or loaded with complex lithium (greases for holding at high loads and high speeds).
- the invention makes it possible to improve the cleaning efficiency while using less toxic products.
- methanol is a toxic product that is not suitable for use in an open environment (vapor phase cleaning).
- the compositions according to have reduced ignition risks when used as cleaning agents, especially for cleaning in the vapor phase, with respect to a composition in which the HFCO-1233zd: TDCE mass ratio is lower (for example is about 50:50).
- the cleaning power of the composition tends to decrease (at least vis-à-vis some fats such as mineral fats loaded lithium / calcium or complex lithium loaded) when the proportion of HFCO-1233zd increases and exceeds a certain threshold.
- the binary compositions of HFCO-1 233zd and TDCE in which the weight ratio HFCO-1233zd: TDCE is between 57:43 and 65:35, preferably between 58:42 and 63:37, more particularly preferably between 59:41 and 61:39, constitute a particularly good compromise since they have both low risks of ignition during use for cleaning in the vapor phase, and satisfactory cleaning properties, in particular vis-à-vis for certain fats such as mineral fats loaded with lithium / calcium or loaded with complex lithium.
- the invention proposes the use of cleaning compositions having a boiling point which is in practice compatible with the constraints related to the cleaning application (in particular in the vapor phase), and in particular the handling constraints.
- the boiling point of the cleaning compositions in the context of the invention is higher than that of the HFCO-1233zd used alone, which is about 18 ° C. (such a value posing a problem with respect to constraints mentioned above).
- the invention proposes the use of cleaning compositions having a low GWP and more generally having little negative impact on the environment.
- the invention proposes the use of binary compositions of 1-chloro-3,3,3-trifluoropropene (HFCO-1233zd) and 1,2-transdichloroethylene (TDCE) in the context of the cleaning of solid surfaces.
- the solid surfaces to be cleaned may be electronic boards soiled by a flux of solder, in which case the cleaning process is a defluxing process.
- the solid surfaces to be cleaned may also be metal parts, glasses, plastics and / or composite materials soiled with grease or oil, in which case the cleaning process is a degreasing process.
- the fats or oils can be of mineral or organic type, with or without fillers. Among these are greases whose high viscosity (greater than 85 mm 2 / s at 40 ° C) makes them difficult to clean. These include mineral fats loaded with lithium / calcium (greases for resistance to high pressures) or loaded with complex lithium (greases for holding at high loads and high speeds). The invention allows a particularly effective cleaning of these greases.
- the cleaning process is based on contacting the solid surfaces to be cleaned with the binary composition of HFCO-1233zd and TDCE.
- the composition may be in the liquid phase and / or in the vapor phase during contacting.
- the contacting is carried out in the vapor phase for greater efficiency.
- the method comprises:
- the method is implemented in an installation comprising at least two tanks, namely a spray tank and a recovery tank.
- the spray tank is filled with cleaning composition in liquid form.
- the solid surfaces to be cleaned are arranged above the spray tank.
- the cleaning composition of the spray tank is heated and partially vaporized.
- the cleaning composition, in vapor form is thus brought into contact with the solid surfaces to be cleaned.
- Materials greyase or other
- Cooling means are arranged above the solid surfaces to be cleaned and allow the condensation of the cleaning composition.
- the condensed cleaning composition is collected in the recovery tank, which in turn feeds the spray tank.
- An addition of each compound of the cleaning composition (HFCO-1233zd and TDCE) or a top-up of the composition itself is generally provided.
- Rinsing solid surfaces with the same cleaning composition (in the liquid phase) or with another solvent can be provided.
- binary composition is meant a composition that contains exclusively or almost exclusively HFCO-1233zd and TDCE.
- the composition comprises a mass proportion of impurities or additives of less than or equal to 1%, preferably less than or equal to 0.5%, or even less than or equal to 0.1%.
- HFCO-1233zd is preferably in its trans form, which has the advantage of being less toxic than the cis form.
- the trans form advantageously represents at least 80% by weight of HFCO-1233zd, preferably at least 90% by weight, more preferably at least 95% by weight, for example at least 98% by weight.
- essentially all of the HFCO-1233zd is in trans form.
- composition of HFCO-1233zd and TDCE used in the context of the cleaning process according to the invention can comprise in its liquid form (the percentages being expressed in mass values):
- the composition for example about 50% HFCO-1233zd and 50% TDCE.
- the composition comprising approximately 50% of HFCO-1233zd and 50% of TDCE has excellent cleaning properties, particularly with respect to certain fats such as mineral fats loaded with lithium / calcium or loaded with complex lithium. It also has a boiling point of about 30 ° C, which is satisfactory vis-à-vis the practical constraints related to the application in cleaning.
- compositions that contain about 50% or less of 50% HFCO-1233zd are particularly effective for cleaning metal solid surfaces because of the high cleaning power of the TDCE; they also have a high boiling point particularly convenient for application to cleaning.
- compositions comprising at least 75% HFCO-1233zd, preferably at least 80%, at least 85%, at least 90% or at least 95% are particularly suitable for cleaning plastic solid surfaces. or composites, since HFCO-1233zd is more compatible than TDCE with plastics.
- the liquid composition comprising about 50% HFCO-1233zd and 50% TDCE does not have a flash point.
- this composition is not azeotropic.
- the relative mass proportions of HFCO-1233zd and TDCE in the liquid composition may vary if the amount of liquid composition itself varies, in case of incident (product leakage, failure of the cooling means ). In such a case, the final liquid composition may then have a flash point, that is to say be flammable.
- the final liquid composition obtained after evaporation of 90% of the mass of an initial liquid composition comprising 50% of HFCO-1233zd and 50% of TDCE is flammable. It is more generally the same for any final liquid composition obtained after evaporation of 90% of the mass of an initial liquid composition comprising a proportion of HFCO-1233zd less than or equal to 56%.
- k for example about 60% of HFCO-1233zd and about 40% of
- compositions of HFCO-1233zd and TDCE h) to k) above make it possible to obtain a greater safety of the cleaning, in particular in the vapor phase, in the event of an incident leading to a decrease in the level of liquid composition (especially in the spray tank).
- these compositions h) to k) exhibit satisfactory cleaning properties, especially with respect to mineral fuels loaded with lithium / calcium or loaded with complex lithium, since a higher concentration of HFCO-1233zd (by for example, a concentration greater than or equal to 70% of HFCO-1233zd) leads to a degradation of the cleaning performance of the composition, especially with respect to the abovementioned fats.
- Example 1 cleaning properties
- test pieces were immersed for 5 minutes in a beaker containing a cleaning composition maintained at 20 ° C and dried in the open air for 5 minutes. After this treatment, the specimens were weighed again to determine the percentage of fat removed by the cleaning composition. The results are expressed as the average value of 3 tests.
- composition 60% trans-HFCO-1233zd and 40% TDCE;
- composition 70% trans-HFCO-1233zd and 30% TDCE;
- Composition 1233zd 100% trans-HFCO-1233zd
- HFCO-1233zd / TDCE binary compositions tested perform better than HFCO-1233zd alone on A grease, B grease and C grease, and perform better than ternary HFCO-1233zd / TDCE composition. at least on fats A and C.
- the binary composition comprising 50% of HFCO-1233zd and 50% of TDCE is characterized by excellent cleaning properties on greases A, B and C, and the binary composition comprising 60 % HFCO-1233zd and 40% TDCE is characterized by excellent cleaning properties at least on greases B and C.
- Binary compositions comprising 70% HFCO-1233zd and 30% TDCE or 80% HFCO-1233zd and 20% TDCE are characterized by a relatively lower efficiency on all fats compared to the binary composition comprising 60% HFCO-1233zd and 40% TDCE.
- the HFCO-1233zd / TDCE binary compositions comprising at least 57% of HFCO-1233zd remain non-flammable even after evaporation of 90% of their mass. Also, these compositions have better guarantees of safety in the context of a cleaning process, especially in the vapor phase, the compositions comprising less than 57% of HFCO-1233zd.
