Description
Vaskemiddel med nedsatt korrosjonsvirkning. Detergent with reduced corrosion effect.
Nærværende oppfinnelse angår vaskemiddelblandinger sorn også i hårdt vann har nedsatt tendens til å angripe kopper, sink og aluminium samt legeringer som inneholder disse metaller. The present invention relates to detergent mixtures which, even in hard water, have a reduced tendency to attack copper, zinc and aluminum as well as alloys containing these metals.
For en tilfredsstillende rengjoringsvirkning er det nodvendig å binde i vaskeopplbsningen forekommende Ca- og Mg-ioner, slik at det fri innhold av disse blir mindre enn 10"? gion/liter. For nærværende anvendes nes^ten-utelukkende- tripolyfosfat, Na^P^O-^Q, for' dette formål, men man har. i dé senere år innsett at den. okede tilforsel av fosfat til avløpsvannet innebærer en sterkt oket tilforsel av næringssalter til innsjo.er og vassdrag med en For a satisfactory cleaning effect, it is necessary to bind Ca and Mg ions occurring in the washing solution, so that the free content of these is less than 10" gion/litre. For the present, tripolyphosphate, Na^P, is used almost exclusively ^O-^Q, for this purpose, but in recent years it has been realized that the increased supply of phosphate to the waste water implies a greatly increased supply of nutrient salts to lakes and waterways with a
påskyndetigjenvoksning som folge. Det er derfor onskelig å accelerated regrowth as a result. It is therefore desirable to
finne fosfatfattige eller fosfatfri erstatningsmidler for tri-polyf osf at. Kompleksdannere av aminokarboksylsyretype, slik som NTA, nitrilotrieddiksyre og EDTA og etylendiamintetraeddiksyre fungerer utmerket men har den ulempe at vaskeopplosningens angrep på kopper, sink og aluminium samt legeringer som inneholder disse metaller okes sterkt,særlig hvis vaskeopplosningen også inneholder blekemiddel av peroksyd. Denne korrosjon er et meget alvorlig teknisk problem, da materiale av kopper, sink og aluminium eller legeringer av disse forekommer i stor utstrekning i vaskeapparater, f.eks. i beskyttelsesrbr for de elektriske varmeelementer av forniklet kopper, i ventilseter av messing, find phosphate-poor or phosphate-free substitutes for tri-polyphosph at. Complex formers of the aminocarboxylic acid type, such as NTA, nitrilotriacetic acid and EDTA and ethylenediaminetetraacetic acid work excellently, but have the disadvantage that the washing solution's attack on copper, zinc and aluminum as well as alloys containing these metals is greatly increased, especially if the washing solution also contains peroxide bleach. This corrosion is a very serious technical problem, as materials of copper, zinc and aluminum or their alloys occur to a large extent in washing appliances, e.g. in protective rubber for the electrical heating elements of nickel-plated copper, in valve seats of brass,
i væsketermometer av kopper, i pumpehjul av sinklegering, i yttertromler av forsinket stål, i pumpehus av lettmetall etc. in copper liquid thermometers, in zinc alloy pump wheels, in galvanized steel outer drums, in light metal pump housings, etc.
Det er tidligere kjent at man kan motvirke metallkorrosjon i vaskemiddelopplosninger som inneholder aminokarboksylsyrer ved tilsetning av en fosforsyreester av alkylglyceryleter eller fosforsyreestere av etylenoksydaddukter av fettalkoholer. I disse tilfeller har imidlertid vaskemiddelopplosningene vært fri for oksydasjonsmidler. Undersbkelser har imidlertid vist at de foreslåtte forbindelser ikke har vært tilstrekkelig korrosjonshemmende overfor de angitte metaller og metall-legeringer, hvis oksydasjonsmidler samtidig er til stede. Metallkorrosjonen i vaskeopplosninger kan forhindres av salter av monocetyl- og monostearylfosfat i kombinasjon med ikke-ion og aniontensider som vanligvis benyttes i vaskemidler, men de nevnte alkylfosfatene har imidlertid den ulempe at de danner tungt opp-løselige kalsium- og magnesiumsalter, hvilket begrenser deres anvendelse, dels til midler for mykt'vann (mindre enn 5°dH)og dels til midler med meget gode kompleksdannende egenskaper for Ca og Mg slike som EDTA og PDTA (propylendiamintetraeddiksyre). Det har nå overraskende vist seg at hvis man til en fettalkohol med 16-18 karbonatomer på i og for seg kjent måte forst anleirer en mindre mengde propylenoksyd, fortrinnsvis 1-2 mol pr. mol alkohol, og deretter omsetter reaksjonsproduktene med polyfosforsyre til tilsvarende alkyleterfosfat, så kommer dette produkt til å vise gode korrosjonshemmende egenskaper i vaskemiddelopplosninger som inneholder aminokarbaksylsyrer og peroksyd uansett vannhårdheten. Det- erholdte alkyletersulfat overfores som regel forst til dettes natrium- eller kaliumsalt, innen det blandes med vaskemiddelets ovrige komponenter, men kan selvsagt også tilfores vaskemiddeloppslemningen i sin syreform. It is previously known that metal corrosion can be counteracted in detergent solutions containing aminocarboxylic acids by adding a phosphoric acid ester of alkyl glyceryl ether or phosphoric acid esters of ethylene oxide adducts of fatty alcohols. In these cases, however, the detergent solutions have been free of oxidizing agents. Investigations have shown, however, that the proposed compounds have not been sufficiently corrosion-inhibiting towards the specified metals and metal alloys, if oxidizing agents are present at the same time. The metal corrosion in washing solutions can be prevented by salts of monocetyl and monostearyl phosphate in combination with non-ionic and anionic surfactants which are usually used in detergents, but the aforementioned alkyl phosphates have the disadvantage that they form poorly soluble calcium and magnesium salts, which limits their use , partly to agents for soft water (less than 5°dH) and partly to agents with very good complexing properties for Ca and Mg such as EDTA and PDTA (propylenediaminetetraacetic acid). It has now surprisingly turned out that if you first add a smaller amount of propylene oxide, preferably 1-2 mol per moles of alcohol, and then converts the reaction products with polyphosphoric acid to the corresponding alkyl ether phosphate, then this product will show good corrosion-inhibiting properties in detergent solutions containing aminocarboxylic acids and peroxide, regardless of the water hardness. The alkyl ether sulfate obtained is usually first transferred to its sodium or potassium salt, before it is mixed with the detergent's other components, but can of course also be added to the detergent slurry in its acid form.
Ved fremstillingen av alkyleterfosfatet anvendes vanligvis en polyfosforsyre med 76-85$ <p>2°5' fortrinnsvis 82- 8k% P20^ og en reaksjonstemperatur på 50-100°C, fortrinnsvis 65-75°C.

EKSEMPEL 1 EXAMPLE 1
I vann av 15° dH, hvorav 1/5 er Mg-hårdhet og h/ 5 Ca-hårdhet In water of 15° dH, of which 1/5 is Mg hardness and h/ 5 Ca hardness
ble folgende vaskemiddelopplosning fremstilt: the following detergent solution was prepared:
Til denne opplosning 1 ble tilsatt 0,<*>+ g/l alkylfosfat eller alkyleterfosfat og 0,5 g Cu-pulver kokes med 100 ml av oppløs-ningen i 30 minutter. i Etter at Cu-pulveret ble filtrert fra ble oppløsningens Cu-innhold bestemt med atomabsorpsjonsfotometer og resultatet anvendes som mål på vaskemiddelopplosningens Cu-korrosjon. To this solution 1, 0.<*>+ g/l of alkyl phosphate or alkyl ether phosphate was added and 0.5 g of Cu powder was boiled with 100 ml of the solution for 30 minutes. i After the Cu powder was filtered out, the solution's Cu content was determined with an atomic absorption photometer and the result is used as a measure of the detergent solution's Cu corrosion.
Av forsokserien fremgår at fosfatesterne av propoksylert stearyl- og fremfor alt cetylalkohol gir en bemerkelsesverdig beskyttelse mot den Cu-korrosjon som forårsakes av EDTA i kombinasjon med pero'ksydblekemiddel. From the trial series it appears that the phosphate esters of propoxylated stearyl and above all cetyl alcohol provide remarkable protection against the Cu corrosion caused by EDTA in combination with peroxide bleach.
Anm. Cetyl(P0)n~fosfat betyr ortofosforsyreesteren av cetylalkohol til hvilken forst n mol propylenoksyd anleires. Note Cetyl(P0)n-phosphate means the orthophosphoric acid ester of cetyl alcohol to which first n moles of propylene oxide are attached.
I IN
EKSEMPEL 2 EXAMPLE 2
Til en vaskemiddelblanding med samme sammensetning som i eksempel 1 med den forskjell at EDTA byttes ut med NTA i samme mengde, ble tilsatt 0,^- g/l alkyleterfosfat, hvoretter Cu-korros j onen ble provet på ovenfor angitt måte. To a detergent mixture with the same composition as in example 1 with the difference that EDTA is replaced by NTA in the same amount, 0.2 g/l alkyl ether phosphate was added, after which the Cu corrosion was tested in the manner indicated above.
I forbindelse med WTA gir således de to cetyleterfosfåtene en markant korrosjonshemming, mens bare stearylCPCOg-fosfatet virker hemmende av de provede stearylforbindelser. In connection with WTA, the two cetyl ether phosphates thus provide marked corrosion inhibition, while only the stearylCPCOg phosphate has an inhibitory effect on the tested stearyl compounds.
EKSEMPEL 3 EXAMPLE 3
Til en vaskemiddelopplosning som inneholder: For a detergent solution containing:
hvorved bestanddelene ble opplost i vann av 5° d.H, tilsettes 0,30 g/l av alkyl- resp. alkyleterfosfat, hvoretter Cu-korrosjonen ble bestemt på tidligere angitt måte. whereby the components were dissolved in water of 5° d.H, 0.30 g/l of alkyl resp. alkyl ether phosphate, after which the Cu corrosion was determined in the previously stated manner.
Den for forsok nr. 13 anvendte talgfettalkohol inneholder 63$ cetylalkohol, 30% stearylalkohol og resten myristyl- henholds-vis arachidylalkohol. Fosfatestere av propoksylerte fettalkoholer er således mer effektive inhibitorer enn tilsvarende estere av etoksylerte alkoholer. The tallow fatty alcohol used for experiment no. 13 contains 63% cetyl alcohol, 30% stearyl alcohol and the rest myristyl alcohol, respectively arachidyl alcohol. Phosphate esters of propoxylated fatty alcohols are thus more effective inhibitors than corresponding esters of ethoxylated alcohols.

To a detergent solution with the same composition as stated in example 3, the following additions were made, after which 100 ml of the solution was refluxed with 0.5 g of zinc powder for 30 minutes, after which the powder was filtered off and the zinc content of the solution was determined by atomic absorption -photometer.
Forsøket viser at et stoff ifolge oppfinnelsen har en betydelig hemmende virkning på vaskeopplosningens sink-korrosjon. The experiment shows that a substance according to the invention has a significant inhibitory effect on the washing solution's zinc corrosion.
EKSEMPEL 5 EXAMPLE 5
Til en vaskemiddelopplosning med samme sammensetning som i eksempel 3 men uten vannglass ble nedenfor angitt tilsetninger gjort, hvoretter 101 0 ml av opplosningen ble kokt med en 3 cm<2 >stor aluminiumsplate i 30 minutter, hvoretter oppløsningens Al-innhold ble bestemt med atomabsorpsjonsfotometer. To a detergent solution with the same composition as in example 3 but without a glass of water, the following additions were made, after which 1010 ml of the solution was boiled with a 3 cm<2>-sized aluminum plate for 30 minutes, after which the Al content of the solution was determined with an atomic absorption photometer.
Også vedrørende Al:-korrosjon viser et stoff ifolge oppfinnelsen god korrosjonshemmende virkning. Also with regard to Al: corrosion, a substance according to the invention shows a good corrosion-inhibiting effect.
De ifolge oppfinnelsen fremstilte vaskemiddelblandinger viser slik som det fremgår av ovens.tående forsok, en meget sterk-reduksjon av korrosjonen overfor kopper, sink og aluminium også ved anvendelse av.hårdt vann ved tilberedning av vaskemiddel-opplosningen. Det har videre ved provevasking vist seg at blandingene ifolge oppfinnelsen gir meget gode vaskeresultater og at de erholdte'vaskemidler dessuten blir lavtskummende, hvilket sistnevnte er viktig-ved anvendelse av nyere typer automatvaskemaskiner. Oppfinnelsen begrenses ikke av de foran angitte blandings-eksempler men lar seg tilpasse på alle normalt i vaskemiddel forekommende typekornbinasjoner, hvor man vil erstatte polyfosfat med kompleksdannere av aminopolykarboksylsyretype utan å oppnå de ved en slik overgang inntredende ulemper i form av korrosjon mot apparatdeler av kopper, sink og aluminium eller disses The detergent mixtures produced according to the invention show, as can be seen from the above test, a very strong reduction in corrosion towards copper, zinc and aluminium, also when using hard water when preparing the detergent solution. It has also been shown by trial washing that the mixtures according to the invention give very good washing results and that the detergents obtained are also low-foaming, the latter being important when using newer types of automatic washing machines. The invention is not limited by the mixing examples given above but can be adapted to all types of grain binations normally found in detergents, where one wants to replace polyphosphate with complex formers of the aminopolycarboxylic acid type without achieving the disadvantages arising from such a transition in the form of corrosion against copper appliance parts, zinc and aluminum or disses
legeringer. alloys.
