holater som i og for seg kjent bringes til å reagere med minst ett stoff av fettaktig eller voksaktig natur eller et stoff som bevirker begrenset oppløselighet av produktet samt ytterligere bringes til å reagere med salicylsyre eller substituert salicylsyre, og eventuelt med vann. holates which are known in and of themselves to be reacted with at least one substance of a fatty or waxy nature or a substance which causes limited solubility of the product and further to be reacted with salicylic acid or substituted salicylic acid, and optionally with water.
Det har tidligere vært foreslått å frem-stille aluminiumsalter av salicylsyre eller substituert salicylsyre, se de australske pa-tenter nr. 218.741 og 226.339, ved å bringe aluminiumalkoholater til å reagere med salicylsyre eller substituert salicylsyre. Ifølge det sistnevnte patent utfelles saltet med vann. Herved dannes det imidlertid de rene salter, mens det ved forslaget ifølge oppfinnelsen dessuten innbygges en hydrolysebegrensende gruppe. Ved denne foran-staltning oppnåes det en kontrollert hydrolysehastighet, så at virkningen vil være langt mere langvarig. It has previously been proposed to produce aluminum salts of salicylic acid or substituted salicylic acid, see the Australian patents no. 218,741 and 226,339, by reacting aluminum alcoholates with salicylic acid or substituted salicylic acid. According to the latter patent, the salt is precipitated with water. In this way, however, the pure salts are formed, while in the proposal according to the invention, a hydrolysis-limiting group is also incorporated. With this procedure, a controlled rate of hydrolysis is achieved, so that the effect will be far more long-lasting.
Stoffer av fettaktig eller voksaktig natur, for eksempel oljesyre, stearinsyre, oleylalkohol, stearinalkohol, cetostearylalko-hol og ricinusolje overfører en del av deres voksaktige eller fettaktige egenskaper til molekylet, så at hydrolysen blir temmelig sterkt retardert eller hindret, alt etter hvil-ken mengde disse materialer er tilstede i. Kontrollert hydrolyse kan også oppnåes ved å tilknytte grupper som gir en begrenset oppløselighet i vandig oppløsning for den resulterende aluminiumforbindelse, slik som benzoatgruppen. Substances of a fatty or waxy nature, for example oleic acid, stearic acid, oleyl alcohol, stearic alcohol, cetostearyl alcohol and castor oil transfer part of their waxy or fatty properties to the molecule, so that the hydrolysis is rather strongly retarded or prevented, depending on the amount these materials are present in. Controlled hydrolysis can also be achieved by attaching groups that provide a limited solubility in aqueous solution for the resulting aluminum compound, such as the benzoate group.
Aluminiumforbindelser som har en-hver ønsket hydrolysehastighet innen visse grenser kan oppnåes ved egnet valg av deri hydrolysebegrensende gruppe, og de rela-tive mengdeforhold av disse grupper i molekylet. Aluminum compounds which have a desired hydrolysis rate within certain limits can be obtained by suitable selection of the hydrolysis-limiting group therein, and the relative amounts of these groups in the molecule.
Stoffene som fåes ifølge denne oppfinnelse har den generelle formel The substances obtained according to this invention have the general formula
hvor X er -OH eller en rest av salicylsyre eller substituert .salicylsyre, Y er -OH eller en rest av salicylsyre eller substituert salicylsyre, idet X og Y ikke samtidig kan være OH, og Z er et stoff som gir en gruppe egnet til å dominere forbindelsens reaktivi-tet med hensyn på hydrolyserende midler. Der hvor både X og Y betegner salicylsyre eller substituert salicylsyre, kan de være like eller forskjellige. Produktet kan være where X is -OH or a residue of salicylic acid or substituted salicylic acid, Y is -OH or a residue of salicylic acid or substituted salicylic acid, X and Y cannot simultaneously be OH, and Z is a substance which provides a group suitable for dominate the reactivity of the compound with regard to hydrolysing agents. Where both X and Y denote salicylic acid or substituted salicylic acid, they may be the same or different. The product can be
en blanding av to eller flere stoffer som svarer til den foranstående formel. a mixture of two or more substances corresponding to the above formula.
Aluminiumalkoholatene fåes fortrins-vis fra en alkohol med 2 til 5 kullstoffatomer. Alkoholen kan ha rett eller forgrenet kjede, kan være mettet eller umettet, substituert eller usubstituert. Alkoholatene av isopropylalkohol og sek-butylalkohol fore-trekkes for de fleste formål. Acyloksy-aluminium-alkoholater kan også anvendes. The aluminum alcoholates are preferably obtained from an alcohol with 2 to 5 carbon atoms. The alcohol can have a straight or branched chain, can be saturated or unsaturated, substituted or unsubstituted. The alcoholates of isopropyl alcohol and sec-butyl alcohol are preferred for most purposes. Acyloxy aluminum alcoholates can also be used.
Stoffene kan fremstilles ved å bringe et aluminiumalkoholat til å reagere med et stoff som inneholder en hydrolysebegrensende gruppe og salicylsyre eller substituert salicylsyre, eller salicylsyre eller substituert salicylsyre og vann samtidig. Eventuelt kan aluminiumalkoholatet bringes til først å reagere med et stoff som inneholder en hydrolysebegrensende gruppe og deretter med salicylsyre eller substituert salicylsyre, eller salicylsyre eller substituert salicylsyre samt vann. The substances can be prepared by reacting an aluminum alcoholate with a substance containing a hydrolysis-limiting group and salicylic acid or substituted salicylic acid, or salicylic acid or substituted salicylic acid and water simultaneously. Optionally, the aluminum alcoholate can be brought to react first with a substance containing a hydrolysis-limiting group and then with salicylic acid or substituted salicylic acid, or salicylic acid or substituted salicylic acid and water.
For å illustrere resultatene som kan fåes ifølge oppfinnelsen har man oppnådd de følgende tall vist i tabellen for hydrolysen av aluminium-p-aminosalicylater ved 37° C i 0,2N saltsyre. To illustrate the results that can be obtained according to the invention, the following figures shown in the table have been obtained for the hydrolysis of aluminium-p-aminosalicylates at 37° C in 0.2N hydrochloric acid.
Med en pufferoppløsning av pH 8 ved 37° C blir et aluminium-p-amino-salicylat-oleat, hvor p-amino-salicylsyre og oljesyre er tilstede i forholdet 1 p-aminosalicylat-radikal til 2 oleatradikaler bare hydrolysert 3 pst. etter 2 timer. Når det ikke er noe oleat tilstede, blir aluminium-tri-p-amino-salicylatet nesten øyeblikkelig hydrolysert, det vil si 90 til 100 pst. i 5 til 10 minutter. With a buffer solution of pH 8 at 37° C, an aluminum p-amino-salicylate oleate, where p-amino-salicylic acid and oleic acid are present in the ratio of 1 p-aminosalicylate radical to 2 oleate radicals, is only hydrolyzed 3 percent after 2 hours. When no oleate is present, the aluminum tri-p-amino salicylate is hydrolyzed almost instantaneously, ie 90 to 100 percent in 5 to 10 minutes.
Fremstillingen av de organiske aluminiumforbindelser ifølge denne oppfinnelsen, illustreres med de følgende eksempler: Eksempel 1. The production of the organic aluminum compounds according to this invention is illustrated by the following examples: Example 1.
Aluminiumisopropylat (25,5 g) opplø-ses i toluen (100 ml) og stearinsyre (mol-vekt 284) (35,5 g) også oppløst i toluen tilsettes langsomt hertil mens temperaturen holdes ved 100—110° C, og den isopropylalkohol som frigjøres, destilleres av. p-amino-salicylsyre (38,3 g) oppløst i varm isopropylalkohol (800 ml) tilsettes mens oljebadtemperaturen holdes ved 100—110° C. Isopropylalkoholen blir deretter avde-stillert og tilslutt blir produktet tørket ved avdestillering av oppløsningsmidlene under redusert trykk, hvilket gir 76,5 g av et svaktfarget pulver, aluminium-mono-stea-rat-di-p-aminosalicylat. Aluminum isopropylate (25.5 g) is dissolved in toluene (100 ml) and stearic acid (mol weight 284) (35.5 g) also dissolved in toluene is slowly added here while the temperature is maintained at 100-110° C, and the isopropyl alcohol which is liberated, is distilled off. p-amino-salicylic acid (38.3 g) dissolved in hot isopropyl alcohol (800 ml) is added while the oil bath temperature is maintained at 100-110° C. The isopropyl alcohol is then distilled off and finally the product is dried by distilling off the solvents under reduced pressure, which gives 76.5 g of a faintly colored powder, aluminum mono-stearate-di-p-aminosalicylate.
Eksempel 2. p-aminosalicylsyre (10,3 g) oppløst i isopropylalkohol (300 ml) tilsettes langsomt til en oppløsning av aluminiumdi-stearat-monoisopropylat i toluen, som opp-varmes av et oljebad som holdes ved 105— 110° C, og isopropylalkoholen destilleres. Til slutt blir oppløsningsmidlene fjernet ved destillasjon under vakuum og ga da 50,3 g av et gyllent voksliknende produkt, alumi-niumdistearat-mono-p-aminosalicylat. Example 2. p-aminosalicylic acid (10.3 g) dissolved in isopropyl alcohol (300 ml) is slowly added to a solution of aluminum distearate monoisopropylate in toluene, which is heated by an oil bath maintained at 105-110° C, and the isopropyl alcohol is distilled. Finally, the solvents are removed by distillation under vacuum, yielding 50.3 g of a golden wax-like product, aluminum distearate-mono-p-aminosalicylate.
Eksempel 3. Example 3.
Salicylsyre (27,6 g = 0,2 mol) oppløst i (200 ml) benzen ved oppvarming til 70° ble tilsatt langsomt til aluminium-sek-butylat (24,6 g = 0,1 mol) oppløst i toluen (100 ml) mens det samtidig ble tilsatt oljesyre (28,2 g = 0,1 mol) og vann (0,9 g = 0,05 mol). Re-aksjonsmassen ble kokt under tilbakeløp i 2 timer. Oppløsningsmidlene og mulig fri-gjort isobutanol ble fjernet ved oppvarming under vakuum. Dette ble fortsatt inntil produktet holdt konstant vekt, hvilket ga et aluminium-salicylsyre-hydroksyoleat, hvori salicylsyre, hydroksygruppen og oleatgruppen er tilstede i molforholdet 2 : 0,5 : 0,5. Salicylic acid (27.6 g = 0.2 mol) dissolved in (200 ml) benzene on heating to 70° was added slowly to aluminum sec-butylate (24.6 g = 0.1 mol) dissolved in toluene (100 ml ) while oleic acid (28.2 g = 0.1 mol) and water (0.9 g = 0.05 mol) were added at the same time. The reaction mass was refluxed for 2 hours. The solvents and possible released isobutanol were removed by heating under vacuum. This was continued until the product held a constant weight, yielding an aluminum salicylic acid hydroxyoleate, in which salicylic acid, the hydroxy group and the oleate group are present in the molar ratio of 2:0.5:0.5.
