Definitions
- aqueous treatment agents for the treatment of solid surfaces e.g. B. fibers, textiles, metals, ceramics or glass are strongly acidic or alkaline.
- Technical treatment agents of this type e.g. B. bleach, mercerizing, decoction.
- Cleaning and degreasing agents, descaling, etching, pickling and rust removal agents require the addition of wetting agents. to achieve a quicker and more intimate contact between the treatment agent and the solid surface.
- wetting agents that are suitable for such acidic and alkaline, technical treatment agents must have good water solubility, even in acidic and alkaline medium, and must be largely stable against hydrolysis in these media. Since the technical treatment methods mentioned are often associated with strong mechanical movement, undesirable foaming easily occurs. Suitable wetting agents must therefore be very low-foaming. If this is not the case, the use of anti-foaming agents is necessary. The use of anti-foaming agents is not only associated with costs, but often has undesirable side effects, e.g. B. an uneven treatment of the surface or the formation of hydrophobic residues on the treated surface.
- technical wetting agents should be environmentally friendly, that is, in particular, readily biodegradable and non-toxic to aquatic organisms.
- wetting agents are characterized by very good water solubility, even in the presence of high concentrations of dissolved electrolytes, especially in the presence of acids and alkalis.
- the invention therefore relates to the use of these ether sulfonates as wetting agents, especially in strongly acidic and strongly alkaline technical treatment solutions, especially in solutions which have a pH below 3 or above 10.
- the ether sulfonates to be used according to the invention are therefore preferably mixtures of compounds of the formula 1 in which R 2 is alkenylene, hydroxyalkylene and hydroxyalkenylene groups.
- the starting products of formula 11 are accessible by methods known from the literature. They are manufactured from unsaturated alcohols of the formula R 3 -OH. If X is a number from 1-30, these are, according to the process known from the literature, using X mol of an alkylene oxide of the formula C n H 2n O, for. B. with ethylene oxide or propylene oxide or mixtures of these alkylene oxides. Mixtures of homologous oxalkylates are obtained, the average degree of oxalkylation corresponding to the amount of alkylene oxide added.
- the etherification of the terminal hydroxyl group of the unsaturated alcohols and / or their oxalkylates is carried out by methods which are also known from the literature. You can e.g. B.
- the alcohol or the oxalkylate is converted into the alcoholate with an alkali metal and this with an alkyl halide, for. B. is reacted with an alkyl chloride of the formula R 1 -Cl.
- Another method is to react the alcohol or the oxalkylate with an alkyl halide in the presence of a finely powdered alkali metal hydroxide at an elevated temperature.
- the alkoxylate can 1 is -Cl or R l Br DE-PS-2 800 710 are reacted in the presence of an aqueous solution of NaOH or KOH in accordance with an alkyl chloride or alkyl bromide of the formula R.
- the unsaturated alcohol R 3 OH is preferably an unsaturated fatty alcohol with 16-22 C atoms, ie an alcohol from the group palmitole alcohol, oleyl alcohol, linoleyl alcohol, erucalcohol or a mixture such alcohols, e.g. B. a technical, consisting mainly of such alcohols fatty alcohol cut used.
- Low levels of saturated alcohols, e.g. B. on cetyl and stearyl alcohol are portable, especially if the products of general formula 11 produced therefrom by oxyalkylation and etherification are themselves water-soluble.
- Technical cetyl-oleyl and oleyl-linoleyl alcohol cuts with an iodine number in the range of 70-130 are preferably used.
- Preferred wetting agents of the general formula 1 are preferably obtained by adding 3 to 10 mol of ethylene oxide to these alcohols, etherification with alkyl halide, for. B. R 1 Cl, and sulfonation with S0 3 obtained.
- the wetting agents used according to the invention are distinguished by a particularly low foaming power. This is of particular advantage in strongly alkaline treatment agents, e.g. B. in alkaline cold bleaching liquors, hot bleaching liquors, mercerizing liquors, alkaline boiling and degreasing agents, since such alkaline treatment agents tend particularly to form foam.
- the cause of the foam formation can either be the use of a foaming wetting agent or the formation of highly foaming hydrolysis products under the conditions of the surface treatment, e.g. B. the formation of soaps from hydrolyzed fats or foaming protein breakdown products from protein compounds.
- alkaline treatment agents are e.g. B. mercerizing liquors, alkaline decoction solutions, alkaline degreasing agents and alkaline bleaching baths.
- ether sulfonates as low-foaming wetting agents in aqueous alkaline bleaching liquors is particularly interesting. These contain hydrogen peroxide or compounds which form hydrogen peroxide in aqueous solution as a bleaching agent.
- the pH value of the bleach baths is with strong bases, e.g. B. with NaOH, KOH, Na 2 C0 3 , K 2 C0 3 and / or water glass to 10-14.
- strong bases e.g. B. with NaOH, KOH, Na 2 C0 3 , K 2 C0 3 and / or water glass to 10-14.
- the well-known anionic and nonionic wetting agents which are stable and effective in this medium, tend to produce a lot of foam in the high-speed apparatus. For this reason, the use of foam damping agents, for. B. of the type of silicone oils, common.
- a preferred object of the invention is therefore the use of the ether sulfonates of the general formula I in aqueous cold bleaching solutions containing 0.3-3% by weight of hydrogen peroxide, 0.05-1 mol / l of a strong base from the group sodium hydroxide, potassium hydroxide , Sodium carbonate, potassium carbonate, sodium silicate and / or potassium silicate as low-foaming wetting agent, preferably in an amount of 0.05-1% by weight of the bleaching solution.
- Such bleaching solutions are used at temperatures of 10 - 142 ° C, but preferably at a temperature of approx. 20 ° C (cold bleaching).
