Description
DK 161896 B ! i ]
Opfindelsen angår anvendelse af salte af specielle aroylcarb-oxylsyrer som korrosionsinhibitorer i vandige systemer. J
Korrosionsbeskyttelsen i vandige systemer er et væsentligt 5 problem ved tekniske processer, når derved truede metaller, såsom kobber, zink eller aluminium, rammes. Anvendelsen af korrosionsinhibitorer, f.eks. i rengøringsmidler, kølesmøremidler, hydraulikvæsker eller kølevand, førte hidtil ofte til en række anvendelsestekniske problemer. Skumdannelsen 10 er f.eks. uønsket. Vandopløseligheden eller også vandhård- j hedsstabiliteten er for midlernes brugbarhed ligeledes af betydning. Yderligere spiller toksiciteten og nedbrydeligheden af stofferne samt deres lagringsstabilitet en væsentlig rolle.
15 I den senere tid er der blevet foreslået langkædede alifatiske sulfonamidcarboxylsyrer, f.eks. arylsulfonamidocarboxylsyrer som korrosionsinhibitorer. Disse inhibitorer udviser dog kun 1 en god korrosionsbeskyttelse ved høje koncentrationer og opfylder alligevel hyppigt ikke de ovenævnte anvendelsestekniske 20 krav. ; i
Det har nu vist sig, at man overraskende når til udmærkede j
resultater, når man som korrosionsinhibitorer i vandige systemer anvender alkalimetal- og/eller ammoniumsalte og/eller 25 substituerede ammoniumsalte af forbindelser med formlen I
—( Qj V-C-R3-COOH
30 hvor og R2 betegner hydrogen eller en alkylgruppe med 1-6 carbonatomer, og R^ betegner CH=CH samt (CH^^ eller (CE^)^·
Især egner de forbindelser sig, hvori R^ i den ovenfor anførte 35 formel I betegner en alkylgruppe med 3-4 carbonatomer, og R3 betegner hydrogen.

Det har yderligere vist sig, at foruden alkalimetalsalte, såsom natrium- eller kaliumsalte, egner sig fortrinsvis ammoniumsalte og substituerede ammoniumsalte, såsom mono-, di- - eller trialkanolaminer, diethano-lamin har især vist sig for- 5 delagtig derved.
Korrosionsbeskyttel sesmidleme anvendt ifølge opfindelsen kan i øvrigt anvendes enkeltvis eller i blanding i vandige opløsnin-ger, dispersioner eller emulsioner. Allerede ved ringe koncentrationer er der en kraftig virkning. Det har nemlig vist sig, at der delvis opnås en stadig tilstrækkelig virkning med 0,5 kg/m . Mængder på 0,5-10 kg/m , fortrinsvis 1-10 kg/m , kommer således i betragtning. De i anvendelse kommende midler er desuden udpræget lavtskummende og udviser en god vandhård-15 hedsstabilitet.
Fremstillingen af aroylcarboxylsyrer foregår efter i og for sig kendte metoder. De kan f.eks. opnås gennem Friedel-Crafts-^ acylering af alkylbenzener med tilsvarende cykliske anhydri- der.
Opfindelsen belyses via de efterfølgende eksempler.
Bestemmelsen af korrosionsbeskyttelsesegenskaberne foregår ved undersøgelse af massereduktionen. I detaljer gås frem på følgende måde.
Eksempler 30
For hvert forsøg bliver tre omhyggeligt forbehandlede og vejede forsøgsbånd (ulegeret stål, 80 x 15 x 1 mm) hængt i en 1 liters beholder, der indeholder 800 ml forsøgsvand, 50 ml pufferopløsning samt en defineret mængde af det stof, der skal 35

3 undersøges, og forbliver deri i 3 timer ved stuetemperatur og med 80 omdr./min.
Ud fra vægttabet blev korrosionsbeskyttelsesværdien S bereg-5 net i forhold til en blindprøve.
q — inn η - -i a = vægttab af prøve b b = vægttab af blindværdi i Q i
Det som korrosivt medium benyttede forsøgsvand blev fremstillet ifølge DIN 51360/2 og pufret med ammoniak/ammoniumchlorid.
I nedenstående tabel IV er de resultater angivet, der opnåedes i sammenligning med benzensulfonamidocapronsyre. Fra tabel-^ lerne 1-3 ses, hvilke forbindelser det drejer sig om ved de med A-T betegnede produkter ifølge formel I. De angivne baser blev anvendt til neutralisation af aroylcarboxylsyrerne.
