Definitions
- the invention relates to greasing agents for leather, a process for the production of leathers with favorable water behavior and the use of sulfonated phosphoric acid ester salts for the production of leathers with favorable water behavior.
- the hydrophobizing effect of the phosphoric acid alkyl esters is due to their poor emulsifiability and their low level Resistance to emulsions.
- alkyl phosphates and / or alkyl polyoxyalkylene phosphates with 12 to 14 carbon atoms in the alkyl radicals are often used in practice, which are easier to emulsify in the alkyl radicals than the corresponding phosphoric acid esters with 16 and more carbon atoms.
- none of these measures to improve the emulsifiability and the emulsion resistance lead to satisfactory performance properties of the leather. Due to the insufficient emulsion resistance, the leather is only insufficiently greased and the result is a hard grip.
- Combinations of the phosphoric acid esters with other fatliquoring agents for example sulfonated paraffins, sulfonated fats and / or sulfonated oils, result in an improved grip, but lead to a reduction in the water repellency effect.
- the object on which the invention is based was therefore the development of fatliquoring agents for leather which give leather a favorable water behavior combined with good usage properties, such as grip, grain resistance and / or fullness. Furthermore, the fatliquors to be developed should have good emulsifying power and high emulsion resistance.
- the invention accordingly relates to fatliquoring agents for leather containing alkali, amine and / or ammonium salts of sulfonated phosphoric acid esters, obtainable by reacting phosphoric acid esters of the general formula I.
- radicals R - * - an alkyl or alkenyl group with 8 to 22 C atoms and R ** - and R3 are identical or different and each represent H or an alkyl or alkenyl group with 8 to 22 C atoms, which Indices m, n and p are identical or different and each represent a number between 2 and 4 and the indices x, y and z are identical or different and each represent a number between 0 and 30, with sulfonating agents and subsequent hydrolysis of the products obtained with alkali hydroxides, ammonium hydroxide and / or amines.
- a further subject of the invention is a process for the production of leathers with favorable water behavior, which is characterized in that leather is obtained by reaction after tanning, retanning or dyeing with alkali, A in and / or ammonium salts of sulfonated phosphoric acid esters of phosphoric esters of the general formula I
- the invention furthermore relates to the use of alkali metal, amine and / or ammonium salts of sulfonated phosphoric acid esters, obtainable by reacting phosphoric acid esters of the general formula I.
- radicals R are an alkyl or alkenyl group with 8 to 22 C atoms and R 2 and R3 are identical or different and each represent H or an alkyl or alkenyl group with 8 to 22 C atoms
- the indices, n and p are identical or different and each represent a number between 2 and 4
- the indices x, y and z are identical or different and each represent a number from 0 to 30, with sulfonating agents and subsequent hydrolysis of the products obtained with alkali metal hydroxides, ammonium hydroxide and / or
- leathers with favorable water behavior are understood to mean leathers in which the water passage through the leather cross section is significantly delayed under dynamic conditions and which absorb only small amounts of water in a certain time unit (penetrometer test according to DIN 53338).
- the fatliquoring agents according to the invention preferably contain alkali salts of sulfonated phosphoric acid esters and particularly preferably alkali salts of sulfonated phosphoric acid esters, which are accessible by reaction of those phosphoric acid esters of the general formula I in which the radicals R are an alkyl or alkenyl group with 12 to 18 C atoms and R 2 and R - are the same or different and each represent H or an alkyl or alkenyl group with 12 to 18 C atoms, the indices m, n and p stand for the number 2 and the indices x, y and z are the same or different and each represent a number between 0 and 10.
- the sulfonation of the phosphoric acid esters of the general formula I are carried out analogously to the processes described in DE-OS 3802815 and DE-0S 38 12 718, preferably at temperatures between 20 and 120 ° C., particularly preferably at temperatures between 30 and 100 ° C., for example performed with sulfuric acid, oleum, chlorosulfonic acid or S ⁇ 3 ⁇ containing gas mixtures.
- Gas mixtures of SO3 and air or inert gases, for example nitrogen, in which the S03 content is between 1 and 10% by volume are particularly preferred as sulfonating agents.
- the molar ratio of the double bond equivalents contained in the starting material to be used SO3 is preferably between 20 and 0.5, particularly preferably between 10 and 0.6.
- the sulfonations are carried out continuously or batchwise in customary reactors suitable and customary for the sulfation of fatty alcohols or the sulfonation of fatty acid esters, alkylbenzenes or olefins, for example of the Fallfil type, (Kirk-Othmer: "Encyclopedia of Chemical Technology” 22 , 28 ff (1983)).
- reaction mixture After sulfonation has ended, it may be expedient to subject the reaction mixture to an aging process.
- the reaction mixture is left to stand or stirred for more than 0 to 240 minutes, particularly preferably within 1 to 30 minutes, preferably at 10 to 120 ° C., particularly preferably at 60 to 100 ° C.
- the mixture is then hydrolyzed with an aqueous solution of alkali metal hydroxides, ammonium hydroxide and / or amines or with anhydrous amines by adding the reaction mixture to the aqueous solution or the anhydrous amines or the aqueous solution or the anhydrous amines to the reaction mixture.
- the optionally aged sulfonation product is preferably added to an aqueous solution of alkali metal hydroxides, ammonium hydroxide and / or amines, 1 to 1.5 moles of hydroxides and / or amines being used per mole of sulfur trioxide added.
- Sodium hydroxide, potassium hydroxide, ammonium hydroxide, diethanolamine, triethanolamine and / or pyridine are preferably used for neutralization. It is particularly preferred to hydrolyze with aqueous solutions of sodium and / or potassium hydroxide.
- the concentration of the hydroxides and / or amines in the aqueous solutions is preferably chosen so that the end product forms a still free-flowing or pumpable aqueous solution.
- Alkali, amine and / or ammonium salts of sulfonated phosphoric acid esters are in the form of dark to light yellow solutions. If desired, these solutions can be bleached with hydrogen peroxide solution or alkali hypochlorite solution (chlorine solution) in a manner known per se at 40 to 55 ° C.
- the phosphoric esters of the general formula I required for the preparation of sulfonated phosphoric acid ester salts are obtainable by processes known from the literature. Their preparation is based on alkyl and / or alkenyl alcohols having 8 to 22 carbon atoms, for example octyl, decyl, lauryl, myristyl, cetyl, palmitoleyl, stearyl, oleyl and / or behenyl alcohol . Alkyl and / or alkenyl alcohols having 12 to 18 carbon atoms are preferably used.
- the alkoxylations of saturated and / or unsaturated alcohols with ethylene oxide, propylene oxide and / or butylene oxide, preferably with ethylene oxide, are carried out using known industrial processes ("Chemical Technology", Volume 7, pages 131 to 132, Carl-Hanser-Verlag, Kunststoff, Germany). Vienna (1986)).
- the average degree of alkoxylation x, y or z of the mixtures of homologous alkoxylates obtained corresponds to the molar amount of the alkylene oxides attached and is preferably between 0 and 10.

In these processes, mixtures of phosphoric acid mono-, di- and triesters are formed. With the use of water entraining agents, such ester mixtures can also be obtained directly using orthophosphoric acid.
- reaction conditions above 160 ° C this does not involve conventional esterification, but primarily the formation of di- and polyphosphoric acid, which react in a known manner with alcohols and / or alcohol polyoxyalkylene ethers.
- the optionally alkoxylated alcohols can be reacted with phosphorus oxychloride to produce high-purity phosphoric acid mono-, di- and triesters.
