Definitions

  • z. B. used cooling lubricant emulsions in the chipless or cutting forming of metallic objects. These have similar compositions as the anti-corrosive emulsions, and also have a corrosion inhibiting effect.
  • the average degree of propoxylation is 1 to 4 and the average degree of ethoxylation is 2 to 6, according to the invention solves the problem of providing a low-foaming compound.
  • This compound is preferred when more than 80% of the Alkylenoxydäen are arranged in blocks, the average degree of propoxylation is 1 to 3 and the average degree of ethoxylation is 3 to 5. It is particularly preferred when more than 80% of the Alkylenoxydäen are arranged in blocks, the average degree of propoxylation is 1 to 2 and the average degree of ethoxylation is 4.
  • the sequence of the alkoxylation units there are basically several possibilities: starting from the tallow fatty alcohol, it is possible first to follow an EO and then a PO block, and it is also possible for a PO and then an EO block to join the tallow fatty alcohol first. Likewise, gradients or a statistical distribution are possible.
  • the invention is a chemical compound in which the PO block is directly adjacent to the Taigfettalkohol and followed by the EO block.
  • a compound which is understood to mean “substantially a block structure” is a compound in which on average more than 65% of the alkoxylation units are arranged in blocks.
  • the weight fraction of EO plus half of the weight fraction of PO is between 35 and 50% of the total weight of the emulsifier, more preferably between 40 and 49% and most preferably between 45 and 49%.
  • Another object of the present invention is an emulsifier containing a chemical compound as described above.
  • an emulsion concentrate containing a chemical compound as described above and / or an emulsifier as described above and a hydrocarbon and / or an ester is another aspect of the present invention.
  • the emulsion concentrate according to the invention may additionally contain one or more additives selected from the group consisting of water, biocides, corrosion inhibitors, fragrances, pesticides, pharmaceuticals, buffers, viscosity regulators, antifreeze agents, defoamers, dyes, complexing agents, salts and coemulsifiers.
  • Biocides are compounds that kill bacteria.
  • An example of a biocide is glutaraldehyde.
  • the advantage of using biocides is that they counteract the spread of pathogens and increase the life of the emulsion.
  • carboxylic acids As a corrosion inhibitor z. B. carboxylic acids. These can be straight-chain or branched. Mixtures of various carboxylic acids may be particularly preferred. Caprylic acid, ethylhexanoic acid, isononanoic acid and isodecanoic acid are particularly preferred carboxylic acids. Since anticorrosive emulsions often neutral to are weakly alkaline, it may be advantageous to use the carboxylic acids at least partially in neutralized form, ie as a salt. Particularly suitable for neutralization are sodium and / or potassium hydroxide, as well as alkanolamines. Particularly preferred is the use of mono- and / or trialkanolamines. The use of dialkanolamines is less preferred because of the danger of formation of nitrosamines. However, dialkanolamines can also be used alone or together with mono- and / or trialkanolamines for neutralization.
  • Fragrances can be individual compounds or mixtures of alcohols, aldehydes, terpenes and / or esters.
  • fragrances are: Lemongrass OiI, Cochin,
  • pesticides are understood as meaning all plant protection agents and pest control agents.
  • the pesticides can be subdivided according to their target organisms into: acaricides, algicides, bactericides, fungicides, herbicides, insecticides, molluscicides, nematicides, rodenticides, avicides and virucides.
  • Buffers are all compounds which are capable of keeping the pH of a composition substantially constant with little acid or base addition.
  • Viscosity regulators serve to adjust the flow properties of liquids.
  • Antifreezes are used to protect compositions from solidification at low temperatures. Their use makes it possible to use the composition over a wider temperature range. Examples of antifreeze are: glycerol, glycol and ethanol.
  • Defoamers are formulations with pronounced interfacial activity which are suitable for suppressing undesirable foaming (for example in wastewater treatment, papermaking, washing in washing machines) or destroying already formed foam.
  • Silicone oils with dispersed silica particles are widely used, but homogeneous defoamers are also included here.
  • Dyes may include, but are not limited to, Acid Blue 9, Acid Yellow 3, Acid Yellow 23, Acid Yellow 73, Pigment Yellow 101, Acid Green 1, Acid Green 25. The advantage of using dyes is that they give the composition a distinctive and distinctive character Give color and make it easy to distinguish.
  • Complexing agents are compounds that are able to bind cations. This can be used to reduce the hardness of the water and to precipitate interfering heavy metal ions. Examples of complexing agents are NTA, EDTA, MGDA and GLDA. The advantage of using these compounds is that many compounds perform better in soft water; In addition, by reducing the water hardness, the occurrence of limescale during and after the use of the composition can be reduced or avoided.
  • Salts can accomplish various tasks, and the nature of the salts which can be used according to the invention is therefore very large. Mention may therefore be given, by way of example only, to the salts of the carboxylic acids which, as described above, may be used as corrosion inhibitors.
  • Another ingredient may be co-emulsifiers.
  • An emulsion concentrate in which the coemulsifier (s) is / are selected from the group consisting of ionic surfactants, alcohols and hydrotropes is preferred.
  • Ionic surfactants can be both anionic and cationic surfactants.
  • anionic surfactants are: carboxylates, sulfonates, sulfo fatty acid methyl esters, sulfates, phosphates.
  • cationic surfactants are: quaternary ammonium compounds.
  • Alcohols are compounds that have an OH functionality. Examples are: ethanol, glycol.
  • Hydrotopes are z. B. salts based on pergonic acid.
  • An emulsion comprising a chemical compound as described above and / or an emulsifier as described above and a hydrocarbon and / or an ester as well as water constitutes a further subject of the present invention.
  • An emulsion which additionally contains one or more additives selected from the group consisting of biocides, corrosion inhibitors, fragrances, pesticides, pharmaceuticals, buffers, viscosity regulators, antifreeze agents, defoamers, dyes, complexing agents, salts and coemulsifiers is preferred.
  • the co-emulsifier (s) is selected from the group consisting of ionic surfactants, alcohols and hydrotropes.
  • Emulsifier 1 (comparison): Cetyl oleyl alcohol x 5 EO
  • Cetyl-oleyl alcohol x 5 EO was prepared by ethoxylation of cetyl-oleyl alcohol (iodine number about 60 g of iodine / 100 g) with 5 molar equivalents of EO by means of KOH catalysis. This type of emulsifier is considered a standard product for the preparation of emulsion concentrates.
  • Emulsifier 2 (inventive): tallow fatty alcohol x 2 PO x 4 EO
  • Emulsifier 3 (comparison): tallow fatty alcohol x 2 PO x 7 EO Taigfettalkohol C16C18 was reacted analogously to Example 2 with 2 molar equivalents of PO, but then with 7 molar equivalents of EO.

Then, by means of a propeller stirrer, a power of about 10 kW / m 3 was introduced for 15 minutes.
  • the resulting emulsions of yellow or blue-colored oil were mixed and then stored at a defined temperature (see the following table). At regular intervals, the emulsions were manually shaken, a sample taken and the proportion of green droplets formed by coalescence determined by microscopy and electronic image analysis. The measured green shares were then plotted against the storage time and fitted by the following function according to the method of least squares:
  • Sunflower oil (56 mm 2 / s at 25 ° C) and paraffin oil (30 mm 2 / s at 25 ° C) were used as oils.
  • Paraffin oil 70 ° C ⁇ -3 -0.7 -0.7
