Abstract
Fremgangsmåte til bearbeiding av nikkelsuper-legeringer, hvorved det først anvendes en varmevirkningsprosess, eksempelvis laser- eller elektrisk utladningsbearbeiding, for fjerning av materiale,. men under etterlating av et omstøpt lag. I til-slutning benyttes en kjemisk behandlingsprosess hvor det anvendes et etsemiddel som bare angriper og fjerner det omstøpte lag. Etsemidlet inneholder 40-60 volum* HNO, 5-20 volum* HC1 og 20-55 volum* H0, tilsatt 0,016-0,025 mol/liter FeClog minst 0,008 mol/liter CuS0. Det tilsatte FeCløker fjerningshastigheten, men har tendens til å forårsake uønsket gropkorrosjon og interkrystallinsk etsing. Disse tendenser forebygges av det tilsatte CuS0, og molforholdet mellom CuSOog.FeCler fortrinnsvis 2:1. Den gunstige kombinasjon av FeClog CuS0kan finne anvendelse i andre etsemidler.A method for processing nickel superalloys, in which a heat action process, for example laser or electric discharge processing, is first used for removing material. but leaving a recast layer. Finally, a chemical treatment process is used in which an etchant is used which only attacks and removes the recast layer. The etchant contains 40-60 volumes * HNO, 5-20 volumes * HCl and 20-55 volumes * H0, added 0.016-0.025 mol / liter FeClog at least 0.008 mol / liter CuSO. It added FeCløker removal rate, but tends to cause unwanted pitting corrosion and intercrystalline etching. These tendencies are prevented by the added CuSO, and the molar ratio of CuSO and FeCl is preferably 2: 1. The beneficial combination of FeClog CuSO can be used in other etchants.

Fremgangsmåte ved fremstilling av nye Procedure for manufacturing new ones

Norsk patent nr. 122.590 angår en fremgangsmåte ved fremstilling av nye '^-l6a-methylsteroider ved hvilken der blant annet ved å gå ut fra forbindelser med formelen: hvor R1 er hydrogen eller en acylgruppe, og R2 er hydrogen eller halogen, ved hydroxylering ved carbonatom 11 ad biokjemisk vei, dehydrering i 1-stilling med dehydrerende virkende mikro-organismer eller ved kjemiske dehydreringsmidler, og eventuelt selektiv acylering av den i 21-stilling stående hydroxylgruppe i hvilken som helst rekkefølge får forbindelser av den generelle formel: Norwegian patent no. 122,590 relates to a process for the production of new '^-16a-methylsteroids in which, among other things, starting from compounds with the formula: where R1 is hydrogen or an acyl group, and R2 is hydrogen or halogen, by hydroxylation at carbon atom 11 ad biochemical route, dehydration in the 1-position with dehydrating microorganisms or by chemical dehydrating agents, and optionally selective acylation of the hydroxyl group in the 21-position in any order gives compounds of the general formula:
hvor R og R2 er som ovenfor angitt. De nevnte fremgangsmåte-produkter har stor terapeutisk betydning for behandling av inflammatoriske sykdommer. where R and R2 are as indicated above. The aforementioned process products have great therapeutic value for the treatment of inflammatory diseases.
Det har nu vist seg at man på fordelaktig vis med vesentlig forbedrede utbytter kan komme til de samme forbindelser II ved at en forbindelse med den generelle formel: It has now been shown that the same compounds II can be obtained advantageously with significantly improved yields by a compound with the general formula:
hvor R^ og R2 er som ovenfor angitt, behandles med et N-klor-acylamid eller N-kloracylimid i nærvær av en oxygenholdig mineralsyre, hvorved -C10H- adderes ved <11>)-dobbelbindingen. where R 1 and R 2 are as indicated above, is treated with an N-chloroacylamide or N-chloroacylimide in the presence of an oxygen-containing mineral acid, whereby -C10H- is added at the <11>) double bond.
Foreliggende fremgangsmåte belyses ved den efterfølgende formelrekke hvori de ved fremgangsmåten ifølge patent nr. 122.590 utførte fremgangsmåtetrinn fra utgangsforbindelsen III til det hele tiden 11-hydroxylerte mellomprodukt er utelatt for å få en bedre oversikt. The present method is illustrated by the following series of formulas in which the method steps carried out in the method according to patent no. 122,590 from the starting compound III to the always 11-hydroxylated intermediate are omitted to get a better overview.
Den nye fremgangsmåte har også den fordel overfor fremgangsmåten ifølge patent nr. 122.590 at det ikke kommer an på om den primære 11-hydroxylering fører til et lia- eller 11|3-hydroxyler-ingsprodukt. The new method also has the advantage over the method according to patent no. 122,590 that it does not depend on whether the primary 11-hydroxylation leads to a 11- or 11|3-hydroxylation product.

De nye forbindelser har stor terapeutisk betydning ved behandling av inflammatoriske sykdommer. De i den efterfølgende tabell eksempelvis oppførte fremgangsmåteforbindelser II - V har således i Granuloma pouch-Test efter oral tilførsel av det som standardsubstans kjente hydrocortisonacetat (I) vist seg mange ganger overlegent: The new compounds have great therapeutic value in the treatment of inflammatory diseases. The method compounds II - V listed as examples in the following table have thus proven many times superior in the Granuloma pouch test after oral administration of the standard substance known as hydrocortisone acetate (I):
