Videre angår oppfinnelsen anvendelsen av de på denne måte fremstilte løsninger av polyetersulfonater I som tensid-løs-ninger ved tertiær oljeutvinning. Furthermore, the invention relates to the use of the solutions of polyethersulfonates I prepared in this way as surfactant solutions in tertiary oil extraction.
Konsentrerte vandige løsninger av polyetersulfonater som Concentrated aqueous solutions of polyethersulfonates which
er fortynnet med kortkjedede alkoholer for nedsettelse av viskositeten er kjente, eksempelvis fra EP-A 156 601 og EP-A is diluted with short-chain alcohols to reduce the viscosity are known, for example from EP-A 156 601 and EP-A
206 678. 206,678.
Disse alkoholisk-vandige tensid-løsninger har, når det dreier seg om tekniske løsninger, ofte den ulempe at de ved fallende temperatur allerede ved 20 til 15°C blir faste på vokslignende måte, ettersom polyetersulfonatene krystalliserer ut. Slike blandinger er i praksis ikke lenger transportable, og kan stoppe til rørledninger og blokkere lagertanker. I tillegg er gjenoppløseligheten av polyetersulfonatene også vanskelig. Denne ulempe er spesielt tungtveiende for anvendelsen av disse tensid-løsninger ved utvinning av jordolje i jordens kaldere klimasoner og kalde hav som eksempelvis Nordsjøen. These alcoholic-aqueous surfactant solutions, when it comes to technical solutions, often have the disadvantage that when the temperature drops, they already become solid in a wax-like manner at 20 to 15°C, as the polyethersulfonates crystallize out. Such mixtures are in practice no longer transportable, and can clog pipelines and block storage tanks. In addition, the resolubility of the polyethersulfonates is also difficult. This disadvantage is particularly significant for the use of these surfactant solutions in the extraction of petroleum in the earth's colder climate zones and cold seas such as the North Sea.
Det var således foreliggende oppfinnelses oppgave å stille til disposisjon kuldestabile polyetersulfonat-løsninger. It was thus the task of the present invention to make cold-stable polyethersulfonate solutions available.
Som en følge av dette, ble den innledningsvis definerte fremgangsmåte oppfunnet. Denne fremgangsmåte er kjennetegnet ved at man etter reaksjonen varmer opp reaksjonsblandingen til 60 til 150°C ved 1 til 5 bar, og skiller fra den overveiende vandige fase som derved danner seg. As a result of this, the initially defined method was invented. This method is characterized by the fact that, after the reaction, the reaction mixture is heated to 60 to 150°C at 1 to 5 bar, and separated from the predominantly aqueous phase which thereby forms.
Ved oppvarming av reaksjonsblandingen til 60 til 150'C ved 1 til 5 bar, fortrinnsvis 90 til 105°C ved normaltrykk, danner det seg en fase som i overveiende grad er vandig og en fase som i overveiende grad er organisk. Den i hovedsak vandige fase inneholder ved siden av vann en del av alkanolen og den største del av de uorganiske salter, i hovedsak halogenider som natriumklorid, som stammer fra reaksjonen av II med sulfitt-løsningen, og som er ansvarlige for kuldestabilitetsforholdet for løs-ningene av I. Den i hovedsak organiske fase inneholder ved siden av alkanol og noe vann, resten av de uorganiske salter og nesten hele mengden av polyetersulfonatet I. When the reaction mixture is heated to 60 to 150°C at 1 to 5 bar, preferably 90 to 105°C at normal pressure, a phase which is predominantly aqueous and a phase which is predominantly organic is formed. The mainly aqueous phase contains next to water a part of the alkanol and the largest part of the inorganic salts, mainly halides such as sodium chloride, which originate from the reaction of II with the sulphite solution, and which are responsible for the cold stability of the solutions of I. The mainly organic phase contains, in addition to alkanol and some water, the rest of the inorganic salts and almost the entire amount of the polyethersulfonate I.
Det er hensiktsmessig at faseskillingen også gjennomføres It is appropriate that the phase separation is also carried out
i varm tilstand i det angitte temperaturområde. Etter fraskil-ling av den i overveiende grad vandige fase kan den i overveiende grad organiske fase stilles inn med vann på et tensid-innhold som vanligvis er 25 til 35 vekt%, og tilføres den videre anvendelse. in a warm state in the specified temperature range. After separation of the predominantly aqueous phase, the predominantly organic phase can be adjusted with water to a surfactant content which is usually 25 to 35% by weight, and added to it for further use.
Resten R i polyetersulfonatene I står spesielt for en alkylgruppe med 8 til 25 C-atomer, fortrinnsvis 10 til 22 C-atomer, eksempelvis n-oktyl, 2-etylheksyl, n-nonyl, iso-nonyl, n-decyl, n-undecyl, n-dedecyl, n-tridecyl, iso-tridecyl, myri-styl, cetyl, stearyl og eicosyl, men også for en alkylengruppe med 8 til 25 C-atomer, fortrinnsvis 10 til 22 C-atomer, eksempelvis oleyl, linolyl og linolenyl, eller for en alkylfenylgruppe med 8 til 18 C-atomer, fortrinnsvis 10 til 16 C-atomer i alkylresten, eksempelvis p-decylfenyl, p-dodecylfenyl, p-myri-stylfenyl, p-cetylfenyl og p-stearylfenyl. The residue R in the polyethersulfonates I stands in particular for an alkyl group with 8 to 25 C atoms, preferably 10 to 22 C atoms, for example n-octyl, 2-ethylhexyl, n-nonyl, isononyl, n-decyl, n-undecyl , n-dedecyl, n-tridecyl, iso-tridecyl, myri-styl, cetyl, stearyl and eicosyl, but also for an alkylene group with 8 to 25 C atoms, preferably 10 to 22 C atoms, for example oleyl, linolyl and linolenyl , or for an alkylphenyl group with 8 to 18 C atoms, preferably 10 to 16 C atoms in the alkyl residue, for example p-decylphenyl, p-dodecylphenyl, p-myristylphenyl, p-cetylphenyl and p-stearylphenyl.
Grupperingen A betegner fortrinnsvis en etylengruppe, ved siden av denne imidlertid også en propylen-, 1,2-butylen- eller 2 ,3-butylengruppe. The grouping A preferably denotes an ethylene group, alongside this, however, also a propylene, 1,2-butylene or 2,3-butylene group.
Alkosyleringsgraden n har en verdi på mellom 1 og 15, fortrinnsvis mellom 2 og 6. The degree of alkylation n has a value of between 1 and 15, preferably between 2 and 6.
Kationet M betyr et alkalimetallkation, spesielt natrium eller kalium, eller et ammoniumkation som fortrinnsvis er usubstituert, men som også kan være substituert med G1-C4~ alkylgrupper eller C1-C4-hydroksyalkylgrupper, eksempelvis trimetylammonium, trietylammonium, trietanolammonium eller triisopropanolammonium. The cation M means an alkali metal cation, especially sodium or potassium, or an ammonium cation which is preferably unsubstituted, but which can also be substituted with G1-C4~ alkyl groups or C1-C4 hydroxyalkyl groups, for example trimethylammonium, triethylammonium, triethanolammonium or triisopropanolammonium.
Polyeterhalogenidene II fremstilles vanligvis på kjent måte av de tilsvarende polyeteralkoholer ved reaksjon med et halogeneringsmiddel, fortrinnsvis med et kloreringsmiddel som tionylklorid eller sulfurylklorid. Polyeteralkoholene på sin side er lett tilgjengelige ved alkoksylering av eksempelvis fettalkoholer eller oksoalkoholer. The polyether halides II are usually prepared in a known manner from the corresponding polyether alcohols by reaction with a halogenating agent, preferably with a chlorinating agent such as thionyl chloride or sulfuryl chloride. The polyether alcohols, on the other hand, are easily accessible by carboxylation of, for example, fatty alcohols or oxoalcohols.
Som alkalimetall- eller ammoniumsulfitter egner seg i hovedsak sulfitter, hydrogensulfitter eller disulfitter, som kantioner kommer de kationer i betraktning som er angitt for M. Som eksempler kan nevnes natriumsulfitt, kaliumsulfitt, ammo-niumsulf itt, natriumhydrogensulfitt, kaliumhydrogensulfitt og ammoniumhydrogensulfitt. Alkali metal or ammonium sulphites are mainly suitable sulphites, hydrogen sulphites or disulphites, as cations the cations indicated for M come into consideration. Examples include sodium sulphite, potassium sulphite, ammonium sulphite, sodium hydrogen sulphite, potassium hydrogen sulphite and ammonium hydrogen sulphite.
Reaksjonen av polyeterhalogenidene II til sulfonatene I med den vandige sulfitt-løsning foretas på i og for seg kjent vis. Man arbeider vanligvis med temperaturer fra 130 til 200'C og ved et trykk fra 2 til 5 bar. Man oppnår på denne måte vanligvis høy-viskøse vandige tensid-rløsninger med et høyt innhold av uorganiske salter. Innholdet av I innstilles vanligvis på 25 til 40 vekt%. The reaction of the polyether halides II to the sulfonates I with the aqueous sulfite solution is carried out in a manner known per se. One usually works with temperatures from 130 to 200°C and at a pressure from 2 to 5 bar. In this way, highly viscous aqueous surfactant solutions with a high content of inorganic salts are usually obtained. The content of I is usually set at 25 to 40% by weight.
Som C4-C8-alkanoler egner seg eksempelvis n-butanol, iso-butanol, n-pentanol, iso-pentanol, n-heksanol, n-heptanol og n-oktanol. Spesielt gode resultater oppnår man med en pentanol eller med en blanding av forskjellige pentanolisomerer, fortrinnsvis n-pentanol og iso-pentanol eller med blandinger av disse. Teknisk pentanol utgjør en slik blanding med en sammen-setning av ca. 70 vekt% av n-isomerer og ca. 3 0 vekt% av iso-isomerer. Examples of suitable C4-C8 alkanols are n-butanol, iso-butanol, n-pentanol, iso-pentanol, n-hexanol, n-heptanol and n-octanol. Particularly good results are obtained with a pentanol or with a mixture of different pentanol isomers, preferably n-pentanol and iso-pentanol or with mixtures of these. Technical pentanol constitutes such a mixture with a composition of approx. 70% by weight of n-isomers and approx. 30% by weight of iso-isomers.
Man tilsetter alkanolen til reaksjonsløsningen under eller umiddelbart etter reaksjonen av II med sulfitt. Man kan imidlertid også arbeide slik at man tilsetter alkanolen til den vandige løsning I som allerede er oppvarmet til 60 til 150°C og foretar blandingen med denne først i varm tilstand. Mengden av alkanol velges da slik at den vanligvis utgjør 50 til 250 vekt%, beregnet på mengden av tensider I; de beste resultater oppnår man med 100 til 150 vekt% alkanol. The alkanol is added to the reaction solution during or immediately after the reaction of II with sulfite. However, it is also possible to work in such a way that the alkanol is added to the aqueous solution I which has already been heated to 60 to 150°C and the mixture is carried out with this first in a warm state. The amount of alkanol is then chosen so that it usually amounts to 50 to 250% by weight, calculated on the amount of surfactants I; the best results are obtained with 100 to 150% by weight of alkanol.
Løsningene av polyetersulfonatene I som er fremstilt ved hjelp av fremgangsmåten ifølge oppfinnelsen egner seg på frem-ragende vis som tensid-løsninger ved tertiær jordoljeutvinning, hvor man ved innsprøyting av løsninger av overflateaktive stoffer i de underjordiske jordoljereservoarer setter ned grenseflatespenningen mellom olje og omgivende vann, slik at utbyttet av utvunnet jordolje på denne måte kan forhøyes. The solutions of the polyethersulfonates I which are produced using the method according to the invention are eminently suitable as surfactant solutions in tertiary crude oil extraction, where the interfacial tension between oil and surrounding water is lowered by injecting solutions of surfactants into the underground crude oil reservoirs, so that the yield of extracted petroleum can be increased in this way.
Fremgangsmåten ifølge oppfinnelsen gir tyntflytende, konsentrerte polyetersulfat-løsninger som er kuldestabile til temperaturer på 5 - CC. Den utgjør en enkel og effektiv rense-metode for tekniske løsninger av polyetersulfonatene I, og ved hjelp av denne fremgangsmåte kan man senke løsningenes innhold av uorganiske salter. The method according to the invention produces thin-flowing, concentrated polyether sulphate solutions which are cold-stable to temperatures of 5 - CC. It constitutes a simple and effective cleaning method for technical solutions of the polyethersulfonates I, and with the help of this method the solution's content of inorganic salts can be lowered.
