Definitions

  • the invention relates to the use of certain alkyl polyglycol ether mixed formals as anti-foaming agents in strongly alkaline cleaning agents.
  • Industrial cleaning agents in particular those which are used in automatic systems for cleaning rigid surfaces such as metal, ceramic or glass and in particular for bottle cleaning, are said to have low foaming power with a strong cleaning power exhibit.
  • the industrial cleaning agents of the type mentioned are mostly products which contain strongly alkaline substances such as, in particular, alkali metal hydroxides or also alkali metal silicates or alkali metal orthophosphates, individually or in a mixture. In the case of such products, high demands are placed on the defoamers not only with regard to the anti-foam effect but also with regard to the storage stability in the corresponding solid products.
  • alkyl polyglycol ether mixed formals of the formula are used as anti-foaming agents in alkaline cleaning agents in which R 1 is a straight-chain or branched alkyl or alkylene radical having 8 to 22 carbon atoms, R 2 is a straight-chain or branched alkyl radical having 1 to 5 carbon atoms, m is a number from 2 to 30 and n is a number from 1 to 3.
  • R 1 is an alkyl radical having 12 to 18 carbon atoms
  • R 2 is an alkyl radical having 2 to 4 carbon atoms
  • m is an integer from 7 to 15
  • n is 1.
  • the alkyl polyglycol ether mixed formals of the formula given above which are used can be prepared, for example by reaction of fatty alcohol ethoxylate of the formula with a di-alkyl glycol formal of the formula in the presence of a strong acid, such as sulfuric acid, by heating to temperatures of about 150 ° C. for several hours.
  • R 1 and R 2 have the same meaning as given in formula I.
  • Suitable starting products for the fatty alcohol ethoxylates are straight-chain or branched aliphatic alcohols, such as hexadecyl, tetradecyl and octadecyl alcohols, and the corresponding branched iso alcohols.
  • Branched aliphatic alcohols which can be prepared by the so-called Guerbet reaction (dimerization of primary alcohols) can also be used.
  • synthetic fatty alcohols or mixtures thereof, such as those obtained in oxo synthesis can also be used.
  • the strongly alkaline cleaning agents (pH above 10) contain sodium or potassium hydroxide in particular.
  • other strongly alkaline substances such as alkali carbonate and alkali orthophosphates, are used alone or in a mixture with alkali hydroxides.
  • the alkaline cleaning agents can also contain the usual constituents, such as alkali silicates, alkali borates, polymeric alkali phosphates and / or complexing agents, such as phosphonic acids, in particular 1-hydroxy ethane-1,1-diphosphonic acid, aminotrimethylene phosphonic acid or 2-phosphonobutane-1,2,4-tricarboxylic acid.
  • the molar ratio of Na 2 O or K 2 0: P 2 O 5 can be 1: 1 to 2: 1.
  • sodium tripolyphosphate is used.
  • Fine-particle synthetically produced, water - insoluble, bound water-containing aluminosilicates of the general formula can also be used as substitutes for the polyphosphates in the cat a cation of valence n, preferably sodium, exchangeable for calcium, x a number from 0.7 to 1.5, preferably 0.9 to 1.3, and y a number from 0.8 to 6, preferably of 1 , 3 to 4, which have a calcium binding capacity of 50 to 200, preferably 100 to 200 mg CaO / g of the anhydrous aluminosilicate can be used.
  • aluminosilicates can be crystalline or X-ray amorphous.
  • the crystalline sodium aluminosilicates are preferred, in particular the zeolites A and X.
  • alkali stable anionic surfactants such as alkyl and / or aryl sulfonates, are also suitable as constituents.
  • the amount of anti-foaming agent added is about 0.1 to 1 g / l, based on the solution used. The amount added depends on the desired antifoam effect and the impurities or bath concentration of the cleaning agent.
  • the detergents are generally used with a bath concentration of 0.2 to 10% depending on the intended use.
  • the application temperature is generally between 40 and 90 ° C.
  • the cleaning agents prepared in this way were each stored in closed polypropylene containers at 45 ° C. and the defoamer tests were carried out at intervals of 2 weeks each.
  • the free fall cycle method consists of heating 500 ml of cleaning solution to 60 ° C in a jacketed 2-1 measuring cylinder.
  • this solution is put into constant circulation at a throughput capacity of 4 l / minute so that the solution is sucked from the bottom of the measuring cylinder with a glass tube and in the open via a second glass tube with the 2000 ml mark of the measuring cylinder Case traced. becomes.
  • a constant initial foam volume for example 2000 ml
