Description

Fremgangsmåte til å bedre vannoppløseligheten av alkalisalter av tetrapropylenbenzolsulfonsyre. Process for improving the water solubility of alkali salts of tetrapropylenebenzenesulfonic acid.

Alkalisaltene av tetrapropylenbenzolsulfonsyre utmerker seg som bekjent ved The alkali salts of tetrapropylenebenzenesulfonic acid are distinguished as known by

en utpreget krystallisasjonsevne, som gjør a distinct crystallization ability, which does

For å avhjelpe denne ulempe har det To remedy this drawback it has

å tilsette saltene vannoppløselige uretaner. Denne bedring gjelder homogeniserin-gen av såvel høyere-konsentrerte oppløs-ninger som av pastaer, som derved får ned-satt viskositet og ved lave temperaturer to add to the salts water-soluble urethanes. This improvement applies to the homogenisation of both higher-concentrated solutions and pastes, which thereby have a reduced viscosity and at low temperatures

kan overføres til høyere-konsentrerte opp-løsninger som er lettere å håndtere. For can be transferred to higher-concentrated solutions that are easier to handle. For

gjennomførelsen av fremgangsmåten egner the implementation of the procedure is suitable

seg rettkjedede og cykliske uretaner av ty-pen oxazoliden med formelen: straight-chain and cyclic urethanes of the oxazolide type with the formula:

hvor R, R,, R2, R3 og R4 betyr hydrogen eller en alkylrest med 1—3 C-atomer og blir å velge slik at uretanet forblir vann-oppløselig. where R, R1, R2, R3 and R4 mean hydrogen or an alkyl radical with 1-3 C atoms and must be chosen so that the urethane remains water-soluble.

Uretanene kan anvendes for seg alene eller i kombinasjon med hverandre eller med andre hydrotroptvirkende substanser som toluolsulfat, glykolkarbonat. Deres virksomhet ytrer seg også fordelaktig ved kombinasjon av forskjellige vaskeråstoffer, The urethanes can be used alone or in combination with each other or with other hydrotrope-acting substances such as toluene sulphate, glycol carbonate. Their business is also advantageous when combining different washing raw materials,

f. eks. av tetrapropylenbenzolsulfonat med ikke-ionogene vaskeråstoffer. Alkaliske til-setninger som soda eller dietanolamin er mulige uten videre. e.g. of tetrapropylene benzene sulphonate with non-ionic detergent raw materials. Alkaline additions such as soda ash or diethanolamine are possible without further ado.

Eksempel 1. Example 1.

Tetrapropylenbenzolnatriumsulfonat som inneholder ca. 5 pst. anorganiske salter (i det vesentlige natriumsulfat), reg-net på 100 pst.'s vaskeaktiv substans blir under tilsetning av 15 pst. etyluretan for-arbeidet til en 30 pst.'s homogen oppløs-ning. Denne har et klaringspunkt på ca. 7°. En 30 pst.'s innstilling av tetrapropylenbenzolnatriumsulfonat uten tilsetning av uretan blir først ved 95° klar og homogen. Tetrapropylene benzene sodium sulphonate containing approx. 5 per cent inorganic salts (mainly sodium sulphate), based on 100 per cent washing active substance, is prepared with the addition of 15 per cent ethylurethane into a 30 per cent homogeneous solution. This has a clearing point of approx. 7°. A 30 percent setting of tetrapropylene benzene sodium sulfonate without the addition of urethane only becomes clear and homogeneous at 95°.

Eksempel 2. Example 2.

En 42 pst.'s pasta av tetraprolylenben-zolnatriumsulfonat inneholdende 2-2,5 pst.. anorganiske salter (i det vesentlige natriumsulfat) kan selv ved 100° ikke lenger homogeniseres. Ved tilsetning av 10 pst. oxazolidon får man en blanding som ved oppvarmning til ca. 65° går over til en oppløsning som er homogen og dermed lett lar seg forarbeide. A 42% paste of tetraprolylenebenzene sodium sulphonate containing 2-2.5% inorganic salts (essentially sodium sulphate) can no longer be homogenised even at 100°. By adding 10 percent oxazolidone, a mixture is obtained which, when heated to approx. 65° changes to a solution that is homogeneous and thus easy to process.

Eksempel 3. Example 3.

Trietanolaminsaltet av tetrapropylenbenzolsulfonat blir under tilsetning av 5 pst. etyluretan innstilt på 50 pst. vaskeaktiv substans. Denne blanding er ved -^-2° ennu klar og lite viskos. Den tilsvarende innstilling uten tilsetning av etyluretan er allerede ved værelsestemperatur grumset og tyktflytende. The triethanolamine salt of tetrapropylene benzene sulphonate is adjusted to 50 per cent detergent active substance with the addition of 5 per cent ethyl urethane. At -^-2° this mixture is still clear and slightly viscous. The corresponding setting without the addition of ethyl urethane is already cloudy and viscous at room temperature.

Eksempel 4. Example 4.

En innstilling som inneholder 45 pst. natriumtetrapropylenbenzolsulfonat og 45 pst. av omsetningsproduktet av nonylfenol med 10 mol etylenoksyd, blir under tilsetning av 2,5 pst. etyluretan innstilt på 90 pst. vaskeaktiv substans. Denne innstilling er ved værelsestemperatur en seig pasta, som dog ved oppvarmning til 70—80° går over til en lett håndterbar, nesten homogen tilstand. Uten tilsetning av etyluretan forblir produktet selv overfor de angitte temperaturer tyktflytende og er derfor vanskeligere å forarbeide. A setting containing 45 percent sodium tetrapropylene benzene sulfonate and 45 percent of the reaction product of nonylphenol with 10 moles of ethylene oxide is, with the addition of 2.5 percent ethylurethane, adjusted to 90 percent detergent active substance. This setting is a tough paste at room temperature, which, however, when heated to 70-80° turns into an easily manageable, almost homogeneous state. Without the addition of ethyl urethane, the product remains viscous even at the specified temperatures and is therefore more difficult to process.
