Description
Blekemiddelpreparat.
Foreliggende oppfinnelse vedrører et blekemiddelpreparat, som er egnet til å fjerne
flekker fra tekstilmaterialer.
Mange rensemiddelpreparater inneholder
et uorganisk persalt som f.eks. natriumperborat eller perkarbonat for å tilveiebringe
blekende egenskaper. Disse persalter tilveie-bringer en tilfredsstillende blekning når rense-midlet anvendes ved kokning, idet virkningen
av disse stoffer ved lavere temperaturer er
temmelig langsom. Denne ulempe er blitt av
særlig betyding med den økende bruk av vas-kemaskiner som arbeider ved en temperatur
av f.eks. 50—60 °C. Det er et formål for foreliggende oppfinnelse å tilveiebrige en mer effektiv blekning i løpet av den normale vaske-periode ved denne temperatur enn det oppnåes
med persaltet alene.
Preparatene i henhold til oppfinnelsen kan
også finne anvendelse i tekstilindustrien og i
vaskerier.
Norsk patent nr. 93.469 angår en alter-nativ fremgangsmåte for å oppnå dette mål.
Patentet er rettet mot en blekeprosess som
karakteriseres ved anvendelse av en vandig
oppløsning av hydrogenperoksyd og en organisk ester av en karboksylsyre, hvilken ester
tilfredsstiller en titerprøve som er fullstendig
beskrevet i patents beskrivelse. Patentet er
også rettet mot et preparat som karakteriseres
ved et innhold av uorganisk persalt og den
ovennevnte organiske ester.
I henhold til foreliggende oppfinnelse tilveiebringes et blekemiddelpreparat, hvis bleke-virkning er basert på tilstedeværelse av hydrogenperoksyd i en vandig oppløsning derav, fortrinnsvis avgitt fra et persalt, hvilket preparat eventuelt inneholder en såpe eller et syntetisk, organisk rensemiddel. Preparatet karakteriseres ved at det inneholder en ester av karbonsyre eller pyrokarbonsyre som henholdsvis har formlene:
hvor Rt er en sulfo- eller karboksysubstituert arylgruppe som eventuelt kan være ytterligere substituert med halogen-, metyl- eller nitro-grupper, R2 er en alkyl-, lavere alkenyl, aryl-, aralkyl- eller alicyklisk gruppe som eventuelt kan være substituert med én eller flere halogen-, nitro-, lavere alkoksy-, lavere alkyl-eller cyangrupper, og R3 er en alkylgruppe, idet esteren har en titer efter den i det følgen-de anførte titeringsforskrift av ikke mindre enn 1,0 ml 0,1 n Na2S203. Den ovennevnte titering utføres således: Til en oppløsning, som ved 60 °C inneholder de følgende bestanddeler i 500 ml destillert vann: 1,25 g natrium pyrofosfat-dekahydrat
(Na4<P>207.10<H>20)
0,154 g natriumperborat (NaB02.H2.3H20)
(ved 10,4 % tilgjengelig oksygen)
tilsettes en mengde ester i et ekvimolart forhold til det tilgjengelige oksygen. Vannopp-løselige estere tilsettes direkte til den vandige
oppløsning, andre estere skal oppløses i 10 ml etylalkohol før tilsetningen, og volumet av destillert vann reduseres i slike tilfeller til 490 ml. Sure derivater skal nøytraliseres før tilsetningen. Blandingen omrøres mekanisk ved hjelp av en 1,9 cm glassrører ved 600 om-dreininger pr. minutt og blandingen holdes ved 60 °C. Ef ter 1 minutt og efter 5 minutter føres ut 100 ml's deler og disse pipetteres umiddelbart på en blanding av 250 g knust is og 15 ml iseddik. 0,4 g kaliumjodid tilsettes derpå. Det frigjorte jod titreres umiddelbart med 0,1 N natriumtiosulfat under anvendelse av stivelse som indikator inntil den første forsvinning av den blå farve.
Særlig foretrukne betydninger for Rt er sulfofenyl, karboksyfenyl, sulfo-a-naftyl, sulfo-yQ-naftyl, karboksy-«-naftyl og karboksy-/?-naftyl. Disse kan eventuelt være ytterligere substituert slik som ovenfor angitt.
Særlig foretrukne betydninger av R, er metyl, etyl, propyl, butyl, amyl, heksyl, oktyl, kapryl, dekyl, lauryl, myristyl, cetyl, stearyl, klormetyl, allyl, fenyl, klorfenyl, diklorfenyl, nitrofenyl, metoksyfenyl, bromfenyl, dibrom-fenyl, cyanfenyl, cinnamyl, benzy], cyklohek-syl, klorcykloheksyl, «-naftyl og /3-naftyl. — Disse kan dessuten eventuelt være substituert som ovenfor angitt. Esterne skal ikke gi lett oksyderbare hydrolyseprodukter som f.eks. flerverdige fenoler.
Eksempler på særlig foretrukne estere innenfor oppfinnelsens ramme, dvs. slike som gir en titer av minst 1,0 ml 0,1 N natriumtiosulfat i det ovenfor angitte forsøk, er følg-ende: Natrium-p-sulfofenyletylkarbonat Natrium-p-sulfofenylmetylkarbonat Natrium-p-sulfofenylfenylkarbonat Dietylpyrokarbonat p-karboksyfenyletylkarbonat p-karboksyfenylmetylkarbonat p-karboksyfenyl-fenylkarbonat o-karboksyfenyl-etylkarbonat o-karboksyfenyl-metylkarbonat p-karboksyfenyl-n-propylkarbonat p-karboksyfenyl-n-butylkarbonat benzyl-p-karboksyfenylkarbonat natrium-p-sulfofenyl-n-propylkarbonat natrium-p-sulfofenyl-n-butylkarbonat natrium-p-sulfofenyl-benzylkarbonat p-karboksyfenyl-cykloheksylkarbonat Hydrogenperoksyd kan naturligvis ikke innføres i et fast preparat og blekeoppløs-ninger fremstilt fra hydrogenperoksyd skal fremstilles efter som det kreves for anvendelse. Hydrogenperoksyd kan settes til oppløs-ningen som sådan eller det kan frigjøres in situ fra et persalt.
Ved uttrykket «uorganisk persalt» for-
ståes et salt som vil kunne danne hydrogenperoksyd i vandige oppløsninger. Egnete forbindelser er alkalimetallperborater, perkarbo-nater, perpyrofosfater og persilikater. Disse antas ikke å være virkelige persalter i den strengt kjemiske forstand, men inneholder hydrogenperoksyd bundet til krystallene og som frigjøres i vandig oppløsning.
Preparatet kan anvendes i forbindelse med blekebad av den art som anvendes for behand-ling av tekstilmaterialer og i forbindelse med vaskevæsker av den art som anvendes i vaskerier og i forbindelse med faste blekepreparater. Faste blekepreparater kan foruten et persalt og en ester i henhold til oppfinnelsen inneholde inerte salter, alkaliske midler og en liten mengde av et rensemiddel. Preparatet kan videre anvendes i forbindelse med rensemiddelpreparater, som inneholder et organisk rensemiddel, som kan være såpe eller et organisk såpefritt rensemiddel. Egnete organiske såpe-frie rensemidler er alkylarylsulfonater, alkyl-sulfater og saltene av estere eller etere av isetionsyre. Preparatene i henhold til oppfinnelsen skal fortrinnsvis inneholde en eller flere alkaliske stoffer i slike mengder at lig-nende preparater som ikke inneholder estere, vil gi en pH-verdi innenfor området 9-11 når de oppløses til den ønskede blekekonsentra-sjon. De mest vanlige rensemiddelpreparater inneholder alkaliske materialer, som er til-strekkelig for dette formål. Passende alkaliske materialer er f.eks. såpe, alkali-metall-karbo-nater, fosfater (innbefattet ortofosfater og vannoppløselige kondenserte fosfater, som f.eks. tripolyfosfater og pyrofosfater) og sili-kater.
Når preparatet anvendes i forbindelse med andre bleke- eller vaskevæsker, bør det i bleke-eller vaskevæskene før tilsetningen av esteren fortrinnvis være tilstede alkali i en mengde til å gi en utgangs-pH av 9-11.
Preparatene i henhold til oppfinnelsen kan inneholde hvilke som helst av de vanlige hjel-pemidler som er til stede i bleke- og rensemiddelpreparater. Det' skal nevnes supplemen-terende byggere, inerte og organiske materialer som f.eks. metallsulfater, klorider, karboksymetylcellulose og fluorescerende midler.
Preparatene i henhold til oppfinnelsen må ikke inneholde vann i en mengde som er til-strekkelig til å muliggjøre en merkbar kjemisk reaksjon mellom komponentene før bruken.
Den mengde av persaltet og esteren som kan være til stede i preparatene i henhold til oppfinnelsen, vil bero på tiden og temperatu-ren for blekingen, blekingsgraden som kreves, konsentrasjonen av blekeoppløsningen og den spesielle ester og persaltet som anvendes. Under de fleste forhold skal disse mengder være slik at det fåes en persaltkonsentrasjon i opp-løsningen svarende til 0,001 til 0,1'% tilgjengelig oksygen.
Idet man tar hensyn til disse faktorer, kan det oppnåes blekeeffekter med preparatene i henhold til oppfinnelsen som inneholder vidt varierende forhold mellom persaltet og esteren. Det er hensiktsmessig å måle aktivi-teten av persaltet uttrykt som tilgjengelig oksygen. Generelt foretrekkes det forhold av fra % til 2 og særlig fra y2 til iy2 molekyl av esteren pr. 1 atom av tilgjengelig oksygen.
(Ved omregningen av slike forhold til vektforhold må man ta i betraktning molekylvekten av esteren og det tilgjengelige oksygeninnhold i det anvendte persalt.) Særlig er det å fore-trekke å bruke omtrentlig kjemisk ekvivalente mengder av ester og persalt.
Når det anvendes oppløsninger som fåes ved å sette hydrogenperoksyd og en ester i henhold til oppfinnelsen til et alkalisk bad, er det foretrukkede vektforhold fra 2 til 15 deler ester til 1 del av hydrogenperoksyd (100%) alt efter molekylvekten av den anvendte ester.
Når preparatene i henhold til oppfinnelsen skal anvendes primært som et blekemiddel, f.eks. til tilsetning til alkaliske tekstilblekebad eller vaskevæsker, kan slike preparater inneholde en hvilken som helst mengde av ester og persalt, idet disse komponenter fortrinnsvis er tilstede i forholdet %. til 2 molekyler av esteren pr. 1 atom av tilgjengelig oksygen, fortrinnsvis y2 til iy2 molekyl pr. 1 atom av tilgjengelig oksygen.
Når et organisk rensemiddel er tilstede i preparatene i henhold til oppfinnelsen, kan det oppnåes en forbedring av blekingen ved normale vaskekonsentrasjoner. Hvis det således f.eks. anvendes et rensemiddelpreparat i henhold til oppfinnelsen ved en konsentrasjon av 1 ■■% i vandig oppløsning, kan det oppnåes for-bedringer hvis det er tilstede mengder så små som 1 vektprosent av persaltet og 2 vektprosent av esteren i preparatet. I slike preparater skal mengden av persalt tilveiebringes i det minste 0,1 % tilgjengelig oksygen basert på preparatet. Generelt vil rensemiddelpreparater inneholde fra ca. 10 til ca. 50 vektprosent av et organisk bindemiddel. Det blandede ester/ persaltinnhold kan være så høyt som 70 vektprosent forutsatt at disse forbindelser brukes i forholdet y± til 2, fortrinnsvis <y>2 til i<y>2 molekyler av esteren pr. 1 atom tilgjengelig oksygen. Effektive mengder av esteren og persaltet i rensemiddelpreparatene vil generelt ligge innenfor området 2 til 30 vektprosent av esteren og 1 til 15 vektprosent av persaltet i preparatet .
De beste resultater ved bleking i henhold til oppfinnelsen oppnåes under forhold hvor det foreligger en effektiv omrøring, f.eks. i en vaskemaskin.
Det følgende eksempel skal tjene til å klargjøre oppfinnelsen.
Eksempel.
Det ble fremstilt blekeoppløsninger som
inneholdt:
0,054 % natrium-dodekylbenzensulfonat 0,018 % kokosnøtt-monoetanolamid 0,115'% natrium-tripolyfosfat 0,045 % natriumsulfat 0,029 % vannfritt alkalisk natriumsilikat 0,004 % natrium-karboksymetylcellulose 0,032 '% natrium-perborat-tetrahydrat
og en ester i en konsentrasjon som anført i den nedenfor følgende tabell. Karboksylsyrene ble omdannet til deres natriumsalter umiddelbart før bruken.
Et stykke bomullsklæde ble flekket ved neddypping i kokende teekstrakt i 1 time. Det ble derpå omhyggelig skyllet, tørket og skåret til stykker hvis prosentrefleksjon ble målt i et Hunter reflektometer under anvendelse av blåfilteret. Prosentrefleksjon ved prøvestyk-kene ble målt påny efter blekning. Blekningen som ble oppnådd, ble uttrykt som forskjellen mellom de to prosentavlesinger på hvert prøve-stykke.
Et stykke av det flekkede bomullsklæde ble neddykket i hver av de friskt fremstilte blekeoppløsninger ved 60 °C i 10 minutter under omrøring. Klædestykkene ble derpå fjernet fra oppløsningene, skyllet tre ganger i destillert vann, strøket og refleksjonen ble målt. Resultatene er oppført i den følgende tabell:
Esterne kan fremstilles ved å la et alkylklorformiat og en fenol reagere med hverandre.
