Abstract

The procedure is characterized by the utilization of a suspending or emulsifying agent made from a mixture of the following components: polyethylene glycol ethers with fatty alcohols of 12 to 14 carbon atoms, polyethylene glycol ethers with fatty alcohols of 16 to 18 carbon atoms, and a mixture of fatty alcohols of 12 to 18 carbon atoms and fatty acid salts of 12 to 18 atoms of carbon.
Applicable as a disintegrating agent for various copper compounds or copper alloy compounds which form over time.

Description

  • This Patent of Invention relates to a new procedure for preparing suspensions of salts of ammoniac, primary amines, secondary amines, tertiary amines and zinc at high concentrations and presenting optimum stability and fluidity and especially ideal ease of application, as a disintegrating agent for various copper compounds or alloys thereof, which form over time (ageing), while at the same time lowering the melting temperature of alloys of tin, lead and silver at multiple concentrations, and in the form of bars, wire or powder, with copper or alloys thereof, thus permitting, with the application of heat, the diffusion of the additive alloy on the surface of the copper compounds.
  • To date, in order to achieve such results it was necessary either to carry out mechanical cleaning of the metal, that is, eliminating oxides or impurities with an abrasive material, or to employ a chemical attack using acid. This was followed by the addition of a suitable alloy and heat to achieve union of the metals and a permanent bond between them. To render this possible it was necessary to provide the system with a compound which would lower the melting point of the metals involved. This procedure also prevents oxidation of the copper compounds during heating and ensures suitable wetting of the suspension on the metal.
  • These compounds, with a high concentration of electrolytes, due to their composition, were supplied either in a highly compact form, similar to tar, or in a liquid form like water.
  • Both these alternative presentations have advantaworking, since the product does not come into contact with the skin. The main disadvantage is that this liquid state does not prevent easy spillage and dripping during work with and handling of the product: the alternative presentation, that is in solid form, prevents accidental spillage but does not manage to avoid the contact with the hands during use, since due to its physical state operatives end up in practice applying it with their fingers.
  • This invention has achieved a stable suspension of the chemical components at a high concentration, thus lending the product a consistency such as to avoid accidental spillage, while permitting it to be applied by brush, thereby achieving a hygienic way of working. Chemically, it is difficult at such high concentrations to achieve a fluid suspension which is stable over time.
  • The procedure of this invention is characterized by the utilization of a suspending or emulsifying agent formed by a mixture of one, two or three of the following components, in multiple proportions:
    • 1. Mixture of polyethylene glycol ethers with fatty alcohols of 12 to 14 carbon atoms, having the following linkage formula 1, originating from a condensate of ethylene oxide on fatty acid C12 to C14:

              CH3-(CH2)n-O-CH2-CH2-O-(CH2-CH2-O-)X-CH2-CH2-O-(CH2)n-CH3   1

         where n = 11, 12 or 13andx: 1<x<25    or having linkage formula 2:

              CH3-(CH2)n-O-(CH2-CH2-O-)X-1-CH2-CH2-OH   2

         where n and x have the same values as in 1.
      The mixture may contain various polyethylene glycols unetherified with fatty acid, linkage formula 3 and non-reacted fatty alcohols of C12 to C14, linkage formula 4.

              HO-(CH2-CH2-O-)X-1-CH2-CH2-OH   3



              CH3-(CH2)n-OH   4

      where n and x have the same values as in 1.
    • 2. Mixture of polyethylene glycol ethers with fatty alcohols of 16 to 18 carbon atoms, having the following linkage formula 5, originating from a condensate of ethylene oxide on fatty acid C16 to C18:

              CH3-(CH2)n-O-CH2-CH2-O-(CH2-CH2-O-)x-CH2-CH2-O-(CH2)n-CH3   5

         where n = 15, 16 or 17and x: 1<x<25    or having linkage structural formula 6:

              CH3-(CH2)n-O-CH2-CH2-O-(CH2-CH2-O-)x-1 -CH2-CH2-OH   6

         where n and x have the same values as in 5.
      The mixture may also contain various polyethylene glycols unetherified with fatty alcohol, of linkage formula 7, and unreacted fatty alcohols of C16 to C18, linkage formula 8

              HO-(CH2-CH2-O-)x-1-CH2-CH2-OH   7



              CH3-(CH2)n-OH   8

      where n and x have the same values as in 5.
    • 3. Mixture of fatty alcohols of 12 to 18 carbon atoms, having the linkage formula 9, and salts of fatty acids of 12 to 18 carbon atoms, having the linkage formula 10, as follows:

              CH3-(CH2)n-CH2-OH   9

      and

              CH3-(CH2)n-COOH   10

      where n = 10 to 16
