Description
Foreliggende oppfinnelse angår som angitt i krav 1 ut^-gangsmaterialer for fremstilling av materialer for anvendelse som røntgenkontrastmidler hvis fremstilling og egenskaper fremgår av norsk patent 147.447.
Tetracarboxylsyretetrakloridene ifølge oppfinnelsen med den generelle formel II kan fremstilles ved at man på kjent vis om-setter et 2,4,6-trijodisofthalsyrediklorid med den generelle formel: hvor R3 er hydrogen eller methyl, med et dicarboxylsyreklorid med den generelle formel:
De nye forbindelser med formel II fåes fra de kjente 5-amino-, hhv. 5-alkylamino-2,4,6-trijodisofthalsyrediklorider ved kondensasjon med dikloridet av alifatisk dicarboxylsyre med formelen C1/C0-X-C0-C1, hvor X er som ovenfor angitt. Som reak-sjonsmedium er organiske oppløsningsmidler, f.eks. aromatiske hydrocarboner som klorbenzen og toluen, men særlig inerte polare oppløsningsmidler som dimethylacetamid, N-rinethylpyrrolidon, dioxan, tetrahydrofuran og andre egnet. Særlig foretrukne oppløsnings-midler er f.eks. dimethylacetamid, dioxan og tetrahydrofuran.
De ved omsetningen dannede dimere tetracarboxylsyretetra-klorider med den generelle formel II krystalliserer enten ut eller isoleres ved inndampning av oppløsningene i vakuum.
De etterfølgende eksempler tjener til ytterligere å belyse foreliggende opp finnelsesgjenstand.
Eksempel 1

En oppløsning av 103 g 5-amino-trijodisofthalsyrediklorid i 412 ml dioxan blir i et oljebad ved 80 - 90°C indre temperatur i løpet av 10 minutter tilsatt 10,3 ml oxalsyrediklorid dråpevis under omrøring. Efter 2 timers omrøring i varmen krystalliserer den nye forbindelse ut, og dette kan påskyndes ved kimtilsetning. Efter omrøring over natten ved værelsetemperatur avsuges bunnfallet og tørres under utelukkelse av fuktighet.
Utbytte av rått oxalsyre-di-(3,5-diklorcarbonyl-2,4,6-tri-jodanilid) er 88,5 g = 7 3,6% av det teoretiske under hensyntagen til et dioxaninnhold på 10 vekt%. Smp.; ingen spaltning inntil 320°C.
