Definitions

  • the invention relates to compositions comprising pentafluorobutane. and the use of these compositions, in particular as a cleaning agent and / or for drying solid surfaces.
  • CFCs Fully halogenated chlorofluorinated hydrocarbons
  • CFC-113 1,1,2-trichloro-1,2,2-trifluoroethane
  • These solvents can be used in different ways manners, mainly cold or hot.
  • compositions based on CFC-113 are also conventionally used as a desiccant, to remove water adsorbed on the surface of parts solid.
  • CFC-113 as well as other chlorofluoroalkanes completely halogenated, is today suspected of causing problems environment, on the one hand in the context of the destruction of the ozone layer stratospheric and secondly as part of the warming of the atmosphere (greenhouse effect).
  • patent application EP-A-431458 proposes a cleaning composition containing an aliphatic hydrofluorocarbon of formula C n FmH 2n + 2-m in which 4 ⁇ n ⁇ 6 and 6 ⁇ m ⁇ 12 and optionally an organic solvent selected from hydrocarbons, alcohols, esters and ketones.
  • One of the objects of the present invention is to provide other compositions forming azeotropes or pseudo-azeotropes, which are particularly effective when they are used as a cleaning agent in solvent cleaning processes.
  • a subject of the invention is also such compositions having properties particularly suitable for cleaning printed circuit boards.
  • Another object of the invention is to provide such compositions devoid of effect destructive to the ozone layer, compositions therefore usable in completely chlorofluoroalkane solvent replacement halogenated.
  • the present invention therefore relates to compositions containing 1,1,1,3,3-pentafluorobutane and ethanol in proportions for which they form an azeotrope or a pseudo-azeotrope, said azeotrope or pseudo-azeotrope consisting of 0.25 to 7.5 g of ethanol per 100 g of 1,1,1,3,3-pentafluorobutane.
  • compositions according to the invention can vary within wide limits, depending on the intended use.
  • compositions according to the invention contain at least 75% by weight of 1,1,1,3,3-pentafluorobutane. They contain advantageously at least 85% by weight. Particularly preferred, they contain at least 90% thereof. They preferably contain not more than 99.7% by weight.
  • 1,1,1,3,3-pentafluorobutane The boiling point of pressure 1,1,1,3,3-pentafluorobutane atmospheric is around 40 ° C (39.9 ° C at 995 mbar). Regarding his impact on the environment, 1,1,1,3,3-pentafluorobutane appears particularly interesting, since due to the absence of chlorine in its molecular structure, it has zero ozone destruction potential.
  • compositions according to the invention can thus contain stabilizers, agents surfactants or any other additives to improve the performances of the compositions according to the invention during their use.
  • the nature and quantity of these additives are depending on the intended use and are easily defined by the skilled person.
  • the amount of additives present in the compositions according to the invention does not exceed about 20% of the weight of the composition, most often not more 10%.
  • 1,1,1,3,3-pentafluorobutane and ethanol have the particularity to form binary azeotropic mixtures.
  • the compositions according to the invention contain the 1,1,1,3,3-pentafluorobutane and ethanol in proportions in which they form an azeotrope or a pseudo-azeotrope.
  • thermodynamic state of a fluid is defined by four interdependent variables: pressure (P), the temperature (T), the composition of the liquid phase (X) and the composition of the gas phase (Y).
  • a true azeotrope is a particular system with 2 or more components for which, at a given temperature and at a given pressure, X is exactly equal to Y.
  • a pseudo-azeotrope is a system with 2 or more components for which, at a given temperature and at a given pressure, X is substantially equal to Y. In practice, this means that the constituents of such azeotropic systems and pseudo-azeotropics cannot be separated easily by distillation and therefore their composition remains constant in solvent cleaning operations, as well as in recovery operations for used solvents by distillation.
  • azeotrope is meant or pseudo-azeotrope, a mixture of two or more constituents whose boiling point (at a given pressure) differs from boiling point of true azeotrope of no more than 0.5 ° C, or still whose vapor pressure (at a given temperature) differs from that of the true azeotrope by up to 10 mbar.
  • 1,1,1,3,3-pentafluorobutane and ethanol form a azeotrope or a binary pseudo-azeotrope when their mixture contains 0.25 to 7.5 g of ethanol per 100 g of 1,1,1,3,3-pentafluorobutane.
  • they form an azeotrope or a pseudo-azeotrope when their mixture contains 0.5 to 7 g ethanol per 100 g of 1,1,1,3,3-pentafluorobutane.
  • the binary composition consisting essentially about 98.4% by weight of 1,1,1,3,3-pentafluorobutane and about 1.6% by weight of ethanol constitutes a true azeotrope, with a boiling point of approximately 39.2 ° C. This composition is very particularly preferred.
  • compositions according to the invention are also inert to against the different types of surfaces to be treated, that these are made of metal, plastic or glass.
  • compositions according to the invention are therefore suitable for any solid object cleaning operation, either simply by immersion of the objects to be cleaned in such a composition, either by washing objects with a cloth, sponge or similar flexible absorbent material impregnated with said composition.
  • compositions according to the invention for this application are those in which ethanol is present in a controlled amount to form a azeotrope or pseudo-azeotrope with 1,1,1,3,3-pentafluorobutane. These compositions indeed have the property of not not separate into their constituents by evaporation or by distillation.
  • the invention therefore also relates to the use of compositions according to the invention, as a cleaning agent, solvent, degreaser, defluxing or desiccant.
  • the invention relates in particular to the use of the compositions according to the invention as a degreasing agent for surfaces solid.
  • the invention relates in particular to the use of the compositions according to the invention as a solvent for degreasing steam surfaces.
  • degreasing steam consists of exposure, at temperature ambient, of the surface to be cleaned, with the vapor of the solvent carried to a boil. By condensing on the surface, the vapor of the solvent removes grease and all other contaminations, by dissolution.
  • the steam degreasing operation conventionally consists of first by immersing the part to be cleaned in one or several baths containing the liquid solvent at temperature boiling, possibly combined with treatment with ultrasound, which removes most of the dirt, and finally by exposing the part to the vapor of the solvent which, by condensing on the surface thereof, achieves a final rinse.
  • this last step can be preceded by spraying the part with liquid solvent.
  • the compositions comprising an azeotrope or pseudo-azeotrope between the 1,1,1,3,3-pentafluorobutane and ethanol are particularly well suited to serve as a solvent in these cleaning processes.
  • the invention also relates to the use of the compositions according to the invention as a card cleaning agent printed circuits contaminated by a flux flux and its residues, i.e. to remove from the surface of these cards the flux flux used in the component welding step and residues of this flow.
  • Parts cleaning electronics, including defluxing printed circuit boards is a particularly important cleaning operation from an industrial and increasingly delicate point of view due to the current evolution towards maps of more and more complex printed circuits dense in electronic components.
  • the processes soldering of electronic components on boards works depositing on them, a film of a flow stripper, followed by the passage of the card thus covered in a molten solder.
  • the flux cleans the conductive metal parts and promotes adhesion of the solder.
  • compositions according to the invention indeed have a high solvent power for the flow and its residues without altering the material constituting the support of the card or the electronic components placed on it.
  • the compositions according to the invention have viscosity and tension characteristics particularly superficial, particularly well suited to this application.
  • compositions according to the invention can also be used in any other process to replace the compositions based on CFC-113. They are particularly suitable good as a desiccant, i.e. to remove water adsorbed on the surface of solid objects requiring a surface perfectly clean, such as printed circuit boards, silicon, optical glasses, timepieces and all others precision parts.
  • azeotropic compositions or pseudo-azeotropics between 1,1,1,3,3-pentafluorobutane and ethanol we used a glass apparatus consisting of a 50 ml boiling flask topped with a condenser at reflux. The temperature of the liquid is measured using a thermometer immersed in the bottle.
  • the determination of the azeotropic composition was made by a statement of the temperature evolution of boiling of the mixture according to its composition.
  • the composition for which a boiling point has been observed minimum is the azeotropic composition (at a pressure of 995 mbar).
  • the table below shows the boiling temperatures obtained for different compositions of 1,1,1,3,3-pentafluorobutane (PFBA) and ethanol (EtOH). It is observed that the best estimate of the composition for which the boiling point is minimum (39.2 ° C) is about 98.4% by weight of 1,1,1,3,3-pentafluorobutane and 1 , 6% by weight of ethanol. The boiling point is 39.4 ° C ⁇ 0.2 ° C for a composition containing approximately from 93.5 to 99.5% by weight of 1,1,1,3,3-pentafluorobutane under a pressure of 995 mbar.
  • PFBA 1,1,1,3,3-pentafluorobutane
  • EtOH ethanol
