Description
01jeopplBselig fyringsolje-korrosjonsbeskyttelsesmiddel. 01soluble fuel oil corrosion protection agent.
Ved lagring av fyringsoljer, dieseloljer og andre hydrokarboner danner det seg på grunn av temperatursvingninger ut-svedningsvann som for en stor del samler seg ved lagringstankens bunn. I denne vanndamp kommer det under rustdannelse til et angrep på metallveggen. Den vandige fase inneholder ved siden av oppløst oksygen og karbondioksyd erfaringsmessig også alkalisalter og andre uorganiske ioner, som vesentlig øker aggresiviteten. I de ugun-stigste tilfelle kan lagerbeholdere ruste igjennom etter et til to år.- Med den økende omstilling fra kull til fyringsolje som husopp-varmning er faren for at utrennende fyringsolje forurenser grunn-vannet blitt, betydelig større enn tidligere. Analogt er transport-systemet (som rørledninger) truet av slik korrosjon. When fuel oils, diesel oils and other hydrocarbons are stored, due to temperature fluctuations, seepage water forms, which for the most part collects at the bottom of the storage tank. This water vapor attacks the metal wall during rust formation. In addition to dissolved oxygen and carbon dioxide, the aqueous phase also contains, according to experience, alkali salts and other inorganic ions, which significantly increase the aggressiveness. In the worst case, storage containers can rust through after one to two years. - With the increasing conversion from coal to fuel oil for house heating, the danger of leaking fuel oil contaminating the ground water has become significantly greater than before. Analogously, the transport system (such as pipelines) is threatened by such corrosion.
Fra U.S. patent nr. 2.935.3<8>9, 2.684.292, 2.793.943, 2.944.969,<2.>994.596, 3.OO3.858 og britisk patent nr. 868.99O er det kjent at bestemte amidokarbonsyrer, aminer og deres salter er iirksomme som korrosjonsmidler under statiske betingelser i for-rådsbeholaere for hydrokarboner. Blandinger av denne type har imidlertid den ulempe at de begunstiger emulgéringen mellom vann-sump og fyringsolje. Det innemulgerte vann gir fyringsoljen et uklart lite tiltalende utseende. Dessuten kan de med vannet innførte salter føre til tilstopping av brennerdysen. From the U.S. Patent Nos. 2,935,3<8>9, 2,684,292, 2,793,943, 2,944,969,<2.>994,596, 3,003,858 and British Patent No. 868,990 it is known that certain amidocarboxylic acids, amines and their salts are active as corrosion agents under static conditions in storage tanks for hydrocarbons. Mixtures of this type, however, have the disadvantage that they favor emulsification between water-sump and fuel oil. The emulsified water gives the fuel oil a cloudy, unattractive appearance. In addition, the salts introduced with the water can lead to clogging of the burner nozzle.
Oppfinnelsens gjenstand er midler som inneholder salter eller ikkestøkiometriske blandinger av The subject of the invention are agents containing salts or non-stoichiometric mixtures of
a) syrer med den generelle formel • a) acids with the general formula •
hvori Z betyr en alkan-, alken eller alkarylrest med minst 4 C-atomer eller en eventuelt alkylsubstituert cykloalkyl- eller aralkylrest med minst4C-atomer, x betyr 2 eller 3i og m betyr 0 til 10 og n betyr 1 til 4, og wherein Z means an alkane, alkene or alkaryl residue with at least 4 C atoms or an optionally alkyl-substituted cycloalkyl or aralkyl residue with at least 4 C atoms, x means 2 or 3i and m means 0 to 10 and n means 1 to 4, and
b) alifatiske, alicykliske, heterocykliske eller aromatiske aminer med minst 4 C-atomer og med en nøytralisasjonsekvivalent på b) aliphatic, alicyclic, heterocyclic or aromatic amines with at least 4 C atoms and with a neutralization equivalent of
30-400, 30-400,
idet blandingene av a) og b) foreligger i forholdet 1 : 9 til 9 : !• since the mixtures of a) and b) are present in the ratio 1 : 9 to 9 : !•
Tilsetningsmengden til innholdet i beholderne kan ut-gjøre 0,0001 til 0,1$. The amount of addition to the contents of the containers may amount to 0.0001 to 0.1$.
Med aminer forstås det ifølge oppfinnelsen primære, sekundære og tertiære alifatiske og cykliske aminer med en nøy-tralisasjonsekvivalent på 3O-4OO. Under de cykliske aminer faller alicykliske og aromatiske forbindelser som kan inneholde det basiske nitrogen i kjernen, på kjernen eller på sidekjeden. Foruten nitrogen kan ringen dessuten inneholde andre heteroatomer, som f.eks. oksygen. De alifatiske aminer inneholder som hydrofob rest mettede og umettede lineære eller forgrenede kjeder, som også kan være avbrutt ved heteroatomer og andre grupperinger. According to the invention, amines mean primary, secondary and tertiary aliphatic and cyclic amines with a neutralization equivalent of 30-400. Under the cyclic amines fall alicyclic and aromatic compounds which may contain the basic nitrogen in the core, on the core or on the side chain. Besides nitrogen, the ring can also contain other heteroatoms, such as e.g. oxygen. The aliphatic amines contain as hydrophobic residues saturated and unsaturated linear or branched chains, which can also be interrupted by heteroatoms and other groupings.
Blandingene ifølge oppfinnelsen er godt oppløselig i flytende hydrokarboner og viser i anvendelseskonsentrasjonen ingen befordring av emulgeringstendensen mellom vann og olje. De omtalte syrer kan fremstilles av de lett tilgjengelige oksalkylater etter kjente fremgangsmåter (tysk patent nr. 887«497i Williamson-syntese). Rustbeskyttelsesvirkningen ble undersøkt under tilpasning til praksisbetingelser etter den statiske vanndråpeprøve ifølge Baker og Zisman (ind. Chem. Eng. 4I; 137-144 (1949)). resp. etter den amerikanske normforskrift MiLL 17353« Som vandig fase tjente en y/ o- ig koksaltoppløsning. Herunder ble det i petriskåler av 5 cm diameter og 1,5 cm høyde fylt fcrekantede prøveblikk med en rund fordypning og oversjiktet med olje. I oljen som skal undersøkes, ble tilsetningsmidlet oppløst med økende konsentrasjon. Etter 15 minutters innvirkningstid ble det i fordypningen med en pipette inndryppet gjennom oljen 1 mm av den 3%-ige koksaltoppløsning. De i siste spalte i følgende tabell angitte tall angir mengden korro-sjonsbeskyttelse i gram/m-^ fyringsolje, hvor det etter en lagrings-tid på 2 uker ikke opptrådte noen rustdannelse. Emulgeringstendensen ble fastslått ved kraftig rysting av like deler fyringsolje- - oppløsninger med destillert vann. De i spalte 4 1 følgende tabell oppførte tall angir volum av emulsjonssjiktet i prosent, som er tilstede 1 time etter foretatt rysting. The mixtures according to the invention are well soluble in liquid hydrocarbons and show no transfer of the emulsification tendency between water and oil in the application concentration. The mentioned acids can be prepared from the readily available oxalkylates according to known methods (German patent no. 887-497 in Williamson synthesis). The rust protection effect was examined under adaptation to practical conditions following the static water drop test according to Baker and Zisman (ind. Chem. Eng. 4I; 137-144 (1949)). respectively according to the American standard regulation MiLL 17353« A 1/0-ig sodium bicarbonate solution served as the aqueous phase. Underneath, rectangular test tins with a round depression were filled in Petri dishes of 5 cm diameter and 1.5 cm height and overlaid with oil. In the oil to be examined, the additive was dissolved with increasing concentration. After 15 minutes of exposure time, 1 mm of the 3% sodium chloride solution was dripped into the recess with a pipette through the oil. The numbers given in the last column of the following table indicate the amount of corrosion protection in grams/m-^ of fuel oil, where no rust formation occurred after a storage time of 2 weeks. The emulsification tendency was determined by vigorous shaking of equal parts fuel oil solutions with distilled water. The numbers listed in column 4 1 of the following table indicate the volume of the emulsion layer in percentage, which is present 1 hour after shaking.
For å øke aldringsbestandigheten er det vanlig til fyringsolje å sette kjente antioksydanter og tungmetalldeaktivatorer. Dessuten kan det for karakteristikk av fyringsoljen anvendes olje-oppløselige fargestoffer. In order to increase aging resistance, it is common to add well-known antioxidants and heavy metal deactivators to fuel oil. In addition, oil-soluble dyes can be used to characterize the fuel oil.
Blandingen ifølge oppfinnelsen utøver ingen uheldig virkning på de nevnte tilsetninger og korrosjonsbeskyttelsen for-blir uforandret. Langtidslagerforsøk har vist at blandingen ifølge oppfinnelsen i tillegg forbedrer oljens lagrings- og fargestabilitet. The mixture according to the invention has no adverse effect on the aforementioned additives and the corrosion protection remains unchanged. Long-term storage tests have shown that the mixture according to the invention also improves the oil's storage and color stability.
Fra tabellen fremgår det at blandingen ifølge oppfinnelsen er utmerkede rustbeskyttelsesmidler uten å ha uheldig enmlsjonstendens. Fremstillingen av blandingene kan foregå ved enkel sammenrøring av amin og syrekomponent. Det herav resul-terende nye tilsetningsmiddel bevirker ved siden av dets rustbe-skyttelsesvirkning på grunn av dens grenseflateaktivitet dessuten en bedre fordeling i forstøvingsbrennere. Brennerforholdet som sådan influeres ikke uheldig. Langtidslagringsforsøk har vist at fyringsoljens lagrings- og fargestabilitet økes. From the table it appears that the mixture according to the invention is an excellent rust protection agent without having an adverse emulsion tendency. The preparation of the mixtures can take place by simple mixing of the amine and acid component. The resulting new additive, in addition to its rust protection effect, also causes a better distribution in atomization burners due to its interface activity. The burner ratio as such is not adversely affected. Long-term storage trials have shown that the fuel oil's storage and color stability are increased.
JJen overraskende fordel ved de omtalte salter består i at man kommer til godt virksomme rustbeskyttelsesmidler som i anvendelseskonsentrasjonen ikke frembringer skadelige emulgerings-tendenser. Derimot avhenger rustbeskyttelsesvirkningen for de kjente salter sterkt av opprinnelsen og de inneholdte stoffer i fyringsoljen. De har ingen utpreget breddevirkning og virker derfor ikke universelt. Ved bestemte fyringsoljekvaliteter viser de en goé rust-hemming; ved andre igjen svikter de totalt. JThe surprising advantage of the mentioned salts is that you end up with highly effective rust protection agents which, in the concentration used, do not produce harmful emulsification tendencies. In contrast, the rust protection effect of the known salts strongly depends on the origin and the substances contained in the fuel oil. They have no distinct broad effect and therefore do not work universally. For certain fuel oil qualities, they show good rust inhibition; at others again they fail completely.
I aen følgende tabell vises overlegenheten av saltene ifølge oppfinnelsen sammenlignet med de tidligere kjente midler i avhengighet av tre forskjellige fyringsoljekvaliteter. In the following table, the superiority of the salts according to the invention compared to the previously known agents is shown in dependence on three different fuel oil qualities.
