Definitions
- Methyl end group capped allcyl and / or alkenyl polyglycol ethers
- the invention relates to methyl-terminated alkyl and / or alkenyl polyglycol ethers, a process for their preparation by methylation of adducts of ethylene oxide and propylene oxide with primary alcohols, agents which contain these substances and the use of the substances for the production of surface-active agents.
- the second group of processes involves the use of surface-active agents which are themselves low-foaming and, if appropriate, additionally have defoaming properties.
- these are nonionic surfactants or surfactant-like systems, such as, for example, fatty alcohol propylene glycol ethers or block polymers of ethylene and propylene glycol, which, however, do not have sufficient biodegradability.
- End group-capped fatty alcohol polyglycol ethers so-called “mixed ethers", which have been established by R. Piorr in Fat.Sei.Technol. 89, 106 (1987).
- These products are generally nonionic surfactants which are butyl-terminated, as described, for example, in EP-A 0124815, EP-B 0303928, EP-B 0324340, EP-A 0420802, DE-A 3928600 and DE-C 4243643 are known.
- a special position is occupied by methyl mixed ethers which have a methyl end group lock and usually by Reaction of the corresponding fatty alcohol polyglycol ethers with methyl halides [US 4587365, BASF] or dimethyl sulfate [EP-B 0302487, BASF].
- EP-A 0161537 (BASF) describes the use, inter alia, of of methyl end group capped mixed ethers for machine bottle cleaning.
- EP-B 0180081 (BASF) proposes the same substances as defoamers for the sugar and yeast industries.
- EP-B 0202638 (BASF) relates to liquid surfactant concentrates for strongly alkaline cleaning agents, containing methyl mixed ethers, alkyl polyglucosides, addition products of maleic anhydride with unsaturated fatty acids and branched fatty acids.
- the object of the invention was therefore to provide new methyl-end-capped alkyl polyglycol ethers which are free from the disadvantages described and which are at least on par with commercial products which are butyl-end-group capped in terms of foam, defoaming, cleaning power and biodegradability. Description of the invention
- the invention relates to methyl-terminated alkyl and / or alkenyl polyglycol ethers of the formula (I)
- R 1 is a linear or branched alkyl and / or alkenyl radical having 6 to 22 carbon atoms
- n is a number from 4 to 15
- m is a number from 1 to 10.
- methyl mixed ethers which have a sequence of an average of 4 to 15 moles of ethylene oxide and 1 to 2 moles of propylene oxide in the polyalkylene oxide chain, compared to known methyl and partly. butyl mixture also have improved foam-suppressing properties. They are also characterized by a very low foaming power, good cleaning performance and satisfactory biodegradability.
- the invention further relates to a process for the preparation of methyl-terminated alkyl and / or alkenyl polyglycol ethers of the formula (I)
- R 1 0 (CH2CH2 ⁇ ) n (CH2CHO) m CH3 (I) in which R represents a linear or branched alkyl and / or alkenyl radical with 6 to 22 carbon atoms, n for numbers from 4 to 15 and m for numbers from 1 to 10, in which primary alcohols of the formula (II)
- the primary alcohols that can be used are, for example, fatty alcohols of the formula (II) in which R 1 represents an alkyl and / or alkenyl radical having 8 to 18 carbon atoms.
- Typical examples are capronic alcohol, caprylic alcohol, 2- ethylhexyl alcohol, capric alcohol, lauryl alcohol, isotridecyl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, linolenyl alcohol, linolenyl alcohol, linolenyl alcohol, linolenyl alcohol and erucyl alcohol and their technical mixtures, for example in the high-pressure hydrogenation of technical methyl esters based on fats and oils or aldehydes from Roelen's oxosynthesis and as a monomer fraction in the dimerization of unsaturated fatty alcohols attack.
- Technical fatty alcohols with 12 to 18 carbon atoms such as coconut, palm, palm kernel or tallow fatty alcohol are preferred.
- Guerbet alcohols of the formula (II) in which R 1 is an alkyl radical having 16 to 20 carbon atoms and branched in the 2-position are also suitable as primary alcohols. Guerbet alcohols are usually produced by basic condensation of fatty alcohols. An overview of this topic is from O'Lenick and Bibo in Soap, Cosm.Chem.Spec. April 52 (1987). Typical examples are 2-hexyldodecanol and 2-0ctyltetradecanol and their mixtures based on technical Cg-Cin fatty alcohols. ° i e Kunststoffge ⁇ named products are characterized by a particularly high cleaning performance and very good biodegradability.
- the ethoxylation and propoxylation of the alcohols mentioned can be carried out in a manner known per se at temperatures from 120 to 180 ° C. in the presence of basic catalysts such as, for example, sodium methylate or calcined hydrotalcite. Accordingly, the alkoxylates can have both a conventional and a narrow homolog distribution. It should once again be expressly pointed out that the sequence of ethoxylation and propoxylation is critical for the performance properties of the products.
- Mixed end ethers which are capped by methyl end groups and are intended to be used for the purposes of the invention obtained exclusively on the basis of alkyl and / or alkenyl polyglycol ethers, which initially have a block of ethylene oxide units and then a small proportion of propylene oxide units.
- Mixed ethers based on alkyl and / or alkenyl polyglycol ethers with an average of 4 to 12 moles of ethylene oxide and 0.5 to 1.5 moles of propylene oxide are particularly preferred.
- the methyl end group closure can also be carried out in a manner known per se, ie using methyl chloride or dimethyl sulfate analogously to US 4587365 or EP-B 0302487. To carry out the reaction, it is advisable to maintain a temperature in the range from 60 to 120 and preferably 80 to 100.degree.
- the end group closure represents a Williamson-type ether synthesis which can only be achieved in the presence of at least stoichiometric amounts of a strong base, such as sodium hydroxide or, in particular, potassium hydroxide. It has also proven to be advantageous to use alkyl and / or alkenyl polyglycol ether, base and methylating agent in a molar ratio of 1: (1.5-2.0): (1.5-2.0).
- the methyl mixed ethers according to the invention are particularly low in foams and are notable for very good defoaming properties, high cleaning performance and good ecotoxicological compatibility.
- cleaning agents are understood to mean, on the one hand, the aqueous solutions intended for direct application to the substrates to be cleaned, and next to them However, the term also includes the concentrates and, if appropriate, solid mixtures intended for the preparation of the application solutions.
- the ready-to-use solutions can be acidic to strongly alkaline and are generally used at temperatures of around 20 to 90 ° C.
- the agents according to the invention can contain further auxiliaries and additives and in particular further anionic, nonionic, cationic and / or amphoteric or zwitterionic surfactants.
- anionic surfactants are alkylbenzene sulfonates, alkane sulfonates, olefin sulfonates, alkyl ether sulfonates, glycerin ether sulfonates, ot-methyl ester sulfonates, sulfo fatty acids, alkyl sulfates, fatty alcohol ether sulfates, glycerin ether sulfates, mono-ether ether sulfate (FOH) sulfates, mono- and dialkylsulfosuccinates.
- anionic surfactants are alkylbenzene sulfonates, alkane sulfonates, olefin sulfonates, alkyl ether sulfonates, glycerin ether sulfonates, ot-methyl ester sulfonates, sulfo fatty acids, alkyl
- nonionic surfactants are fatty alcohol polyglycol ethers, alkylphenol polyglycol ethers, fatty acid polyglycol esters, fatty acid amide polyglycol ethers, fatty fatty acid polyglycol ethers, alkoxylated triglycerides, butyl mixed ethers, alk (en) yl oligoglycosides, fatty acid-N-alkylhydroglucamates, so-called vegetable hydrolysates, and so on basis) polyol fatty acid esters, sugar esters, sorbitan esters and polysorbates. If the nonionic surfactants contain polyglycol ether chains, they can have a conventional, but preferably a narrow, homolog distribution.
- Typical examples of cationic surfactants are quaternary ammonium compounds and ester quats, especially quaterned fatty acid trialkanolamine ester salts.
- amphoteric or zwitterionic surfactants are alkyl betaines, alkyl amido betaines, aminopropionates, amino glycinates, iroidazolinium betaines and sulfobetaines.
- the builders and complexing agents can come primarily alkali metal orthophosphates, polymer phosphates, silicates, borates, carbonates, polyacrylates and gluconates, as well Zeolites, phyllosilicates, citric acid, nitrilotriacetic acid, ethylenediaminetetraacetic acid, l-hydroxyalkane-l, l-di ⁇ hosphonic acids, ethylenediaminetetra- (methylenephosphonic acid) and phosphonoalkane polycarboxylic acids such as, for example, phosphonobutane tricarboxylic acid or alkali metal acetates or alkali metal acetates or alkali metal acids.
- Highly alkaline cleaning agents in particular for bottle cleaning, can also contain considerable amounts of caustic alkali in the form of sodium and / or potassium hydroxide. If special cleaning effects are desired, the agents can also contain organic solvents, for example alcohols, gasoline fractions and free alkanolamines.
- the invention relates to the use of methyl-terminated alkyl and / or alkenyl polyglycol ethers of the formula (I) for the preparation of surface-active agents, in particular low-foaming cleaning agents and defoamers for the sugar and yeast industry, in which they are used in amounts of 1 to 50, preferably 5 to 25% by weight, based on the composition, can be present.
- the reaction mixture is then cooled to 60 ° C. and neutralized with 2N sulfuric acid.
- the crude product is then mixed with an amount of water corresponding to its volume and left at 50 ° C. until phase separation occurs.
- the pure product is obtained by separating off the aqueous phase.
- test foamer TS a 1% by weight aqueous solution of tetrapropylenebenzenesulfonate-triethanolammonium salt
