The glycol radical can be derived from the following glycols: ethylene glycol, propylene glycol, other diols, triols, etc. The ethoxylated alcohol can contain from 1 to 10 moles of ethylene or propylene oxide.
På lignende måte kan jodmolekylet erstattes med brom for fremstilling av de tilsvarende bromider i stedet for jodidene. Når jodidet anvendes,,.er dette organiske fluorid kjent på markedet som "Fluorad FC-13<1>!". En analyse av dette materiale viste at det hadde ovennevnte strukturformel og følgende bruttoformel: Similarly, the iodine molecule can be replaced by bromine to produce the corresponding bromides instead of the iodides. When the iodide is used, this organic fluoride is known on the market as "Fluorad FC-13<1>!". An analysis of this material showed that it had the above structural formula and the following gross formula:
Terpenalkoholen kan være furunålsolje, hvilket er foretrukket, men man kan også anvende andre terpenalkoholer såsom alfa-, beta- og gamma-terpineoler, borneol og lignende. The terpene alcohol can be pine needle oil, which is preferred, but other terpene alcohols such as alpha-, beta- and gamma-terpineols, borneol and the like can also be used.
Som oppløsningsmiddel kan anvendes en alifatisk alkohol, og man kan f.eks. anvende metyl-, etyl-, propyl-, isopropyl-, butyl-, heksyl-, heptyl-, oktylalkohol og høyere, flytende analoger av disse alifatiske alkoholer. Det anvendes fortrinnsvis isopropylalkohol i en mengde på ca. 2-6 vekt-%. An aliphatic alcohol can be used as a solvent, and one can e.g. use methyl, ethyl, propyl, isopropyl, butyl, hexyl, heptyl, octyl alcohol and higher, liquid analogues of these aliphatic alcohols. Isopropyl alcohol is preferably used in an amount of approx. 2-6% by weight.
Som dispergeringsmiddel kan man anvende et etoksylert oleat, fortrinnsvis et etoksylert sorbitolheksaoleat og et etoksylert polyololeat. Videre kan man anvende andre etoksylerte oleater, kinesiske treoljer, samt andre fettsyrer. I visse tilfeller kan disse forbindelser også virke som oppløseliggjørende midler såvel som dispergervingsmidler. An ethoxylated oleate, preferably an ethoxylated sorbitol hexaoleate and an ethoxylated polyoleate, can be used as a dispersant. Furthermore, other ethoxylated oleates, Chinese wood oils and other fatty acids can be used. In certain cases, these compounds can also act as solubilizing agents as well as dispersing agents.

Tabell VII viser effekten av varierende acetyleniske alkoholkonsentrasjoner i sammensetningene: Table VII shows the effect of varying acetylenic alcohol concentrations in the compositions:
Det skal bemerkes at OW-1 (en mindre ren heksynol) er bedre enn de andre acetyleniske alkoholer for hemming av korrosjon. Dette skyldes at urenhetene er andre acetyleniske alkoholer. It should be noted that OW-1 (a less pure hexynol) is better than the other acetylenic alcohols for corrosion inhibition. This is because the impurities are other acetylenic alcohols.
Tabell VIII viser en sammenligning mellom effekten av de forskjellige fluorider. Table VIII shows a comparison between the effects of the different fluorides.
Det fremgår at "FC-13^" fluoridet som inneholdt jod, er det eneste av fluoridene i tabell VIII som var effektivt som korrosj onsinhibitor. It appears that the "FC-13^" fluoride which contained iodine is the only one of the fluorides in Table VIII which was effective as a corrosion inhibitor.
De ovennevnte data viser at midler ifølge foreliggende oppfinnelse er klart bedre enn enkeltkomponentene, og oppfinnelsen er således meget verdifull for bekjempelse av korrosjon som skyldes korroderende syrer såsom svovelsyre, salpetersyre, saltsyre, kullsyre, eddiksyre, andre organiske syrer og lignende, overfor The above-mentioned data show that agents according to the present invention are clearly better than the individual components, and the invention is thus very valuable for combating corrosion caused by corrosive acids such as sulfuric acid, nitric acid, hydrochloric acid, carbonic acid, acetic acid, other organic acids and the like, against
jernholdige metaller. ferrous metals.
Oppfinnelsen kan anvendes i forbindelse med olje og gassfelter hvor man injiserer syre i oljebrønnene for å hindre avleiringer. Videre kan midlene anvendes i forbindelse med syrer som brukes for å rense utstyr fremstilt av jernholdige metaller, f.eks. varmevekslere som skal renses for avleiringer og syre-løselige salter. The invention can be used in connection with oil and gas fields where acid is injected into the oil wells to prevent deposits. Furthermore, the agents can be used in connection with acids used to clean equipment made of ferrous metals, e.g. heat exchangers to be cleaned of deposits and acid-soluble salts.
