Definitions

  • the invention relates to compositions comprising pentafluorobutane and the use of these compositions, in particular as a cleaning and / or drying agent for solid surfaces.
  • CFCs Fully halogenated chlorofluorinated hydrocarbons
  • CFC-113 1,1,2-trichloro-1,2,2-trifluoroethane
  • solvents can be used in various ways, mainly cold or hot.
  • compositions based on CFC-113 are also conventionally used as a desiccant, in order to remove the water adsorbed on the surface of solid parts.
  • CFC-113 like other fully halogenated chlorofluoroalkanes, is today suspected of causing environmental problems, on the one hand in the context of the destruction of the stratospheric ozone layer and on the other hand, as part of the warming of the atmosphere (greenhouse effect).
  • EP-A-0512885 proposes an azeotropic composition comprising by weight 93 to 99% of 1,1,1,3,3-pentafluorobutane (HFA-365mfc) and from 7 to 1% methanol.
  • One of the objects of the present invention is to provide other compositions possibly forming azeotropes or pseudo-azeotropes, which are particularly effective when used as a cleaning agent in solvent cleaning processes.
  • the invention also relates to such compositions having properties particularly suitable for cleaning printed circuit boards.
  • Another object of the invention is to provide such compositions devoid of destructive effect with respect to the ozone layer, compositions which can therefore be used in replacement of solvents based on completely halogenated chlorofluoroalkanes.
  • the present invention therefore relates to compositions comprising 1,1,1,3,3-pentafluorobutane and ethanol.
  • 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 advantageously contain at least 85% by weight thereof. In a particularly preferred manner, they contain at least 90% thereof. They can contain up to 99.995% by weight. Most often, they contain at most 99.9% by weight, preferably at most 99.7% by weight.
  • compositions according to the invention contain from 0.005 to 25% by weight of ethanol. Preferably, they contain from 0.02 to 15%. In a particularly preferred manner, they contain from 0.2 to 10% thereof.
  • 1,1,1,3,3-pentafluorobutane The boiling point of 1,1,1,3,3-pentafluorobutane at atmospheric pressure is approximately 40 ° C (39.9 ° C at 995 mbar). With regard to its 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 a potential for destruction of l 'zero ozone.
  • compositions according to the invention can optionally be present in the compositions according to the invention.
  • the compositions according to the invention can thus contain stabilizers, agents surfactants or any other additive making it possible to improve the performance of the compositions according to the invention during their use.
  • the nature and the quantity of these additives depend on the intended use and are easily defined by a person skilled in the art. As a general rule, the amount of additives present in the compositions according to the invention does not exceed approximately 20% of the weight of the composition, most often not more than 10%.
  • 1,1,1,3,3-pentafluorobutane and ethanol have the particularity of forming binary azeotropic mixtures.
  • a composition according to the invention which is preferred is therefore that which contains 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), temperature (T), composition of the liquid phase (X) and 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 temperature given and at a given pressure, X is substantially equal to Y. In practice, this means that the constituents of such azeotropic and pseudo-azeotropic systems cannot be separated easily by distillation and therefore their composition remains constant in cleaning operations. by solvent, as well as in recovery operations for used solvents by distillation.
  • azeotrope or pseudo-azeotrope means a mixture of two or more constituents whose boiling point (at a given pressure) differs from the boiling point of the true azeotrope by 0, 5 ° C maximum, or whose vapor pressure (at a given temperature) differs from that of the true azeotrope by 10 mbar maximum.
  • 1,1,1,3,3-pentafluorobutane and ethanol form a binary azeotrope or pseudo-azeotrope when mixed 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 from 0.5 to 7 g of ethanol per 100 g of 1,1,1,3,3-pentafluorobutane.
  • the binary composition consisting essentially of approximately 98.4% by weight of 1,1,1,3,3-pentafluorobutane and approximately 1.6% by weight of ethanol constitutes a true azeotrope , whose boiling point is around 39.2 ° C. This composition is very particularly preferred.
  • compositions according to the invention are also inert against the different types of surfaces to be treated, whether these are made of metal, plastic or glass.
  • compositions according to the invention are therefore suitable for any operation for cleaning solid objects, either simply by immersing the objects to be cleaned in such a composition, or by washing the objects with a cloth, sponge or similar flexible absorbent material, impregnated with said composition.
  • compositions according to the invention which are particularly advantageous for this application are those in which the ethanol is present in an amount regulated to form an azeotrope or pseudo-azeotrope with 1,1,1,3,3-pentafluorobutane. These compositions have in fact the property of not separating into their constituents by evaporation or by distillation.
  • the invention therefore also relates to the use of the compositions according to the invention, as 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 solid surfaces.
  • the invention relates in particular to the use of the compositions according to the invention as solvent for the degreasing of steam surfaces.
  • steam degreasing consists of exposing the surface to be cleaned at room temperature to the vapor of the solvent brought to the boil. By condensing on the surface, the solvent vapor removes grease and all other contaminations, by dissolution.
  • the degreasing operation with steam conventionally consists first of all in immersing the part to be cleaned in one or more baths containing the liquid solvent at the boiling temperature, 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 its surface, performs 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 1,1,1,3,3-pentafluorobutane and ethanol are particularly well suited to serve as solvent in these cleaning processes.
  • the invention also relates to the use of the compositions according to the invention as a cleaning agent for printed circuit boards contaminated by a flux flux and its residues, that is to say to remove from the surface of these cards the flux flux used in the soldering step of the electronic components and the residues of this flux.
  • the cleaning of electronic parts constitutes a particularly important cleaning operation from an industrial point of view and increasingly difficult to carry out because of the current evolution towards printed circuit boards. more and more complex and more and more dense in electronic components.
  • the methods of soldering electronic components to the cards involve depositing on the latter, a film of a flux stripper, followed by the passage of the card thus covered in molten solder.
  • the flux cleans the conductive metal parts and promotes the adhesion of the solder.
  • Conventional brazing fluxes consist of collophane, used alone or with certain activators. Brazing performed at high temperature causes at least partial degradation of the flux. This and its residues are removed from the surface of printed circuit boards in a particularly efficient and selective manner with the compositions according to the invention, even when these fluxes are strongly activated.
  • the compositions according to the invention have in fact a high solvent power for the flux and its residues without, however, altering the material constituting the support of the card or the electronic components placed on it.
  • the compositions according to the invention exhibit characteristics of viscosity and surface tension in particular, which are 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 as a desiccant, that is to say to remove water adsorbed on the surface of solid objects requiring a perfectly clean surface, such as printed circuits, silicon plates, optical glasses, parts watchmaking and all other precision parts.
  • the azeotropic composition was determined by recording the evolution of the boiling temperature of the mixture as a function of its composition.
  • the composition for which a minimum boiling point has been observed 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 there 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.
