Fremgangsmåte til fremstilling av vannfrie alkalikloroferrater(II,III) og deres anvendelse. Process for the production of anhydrous alkali chloroferrates (II, III) and their use.
Oppfinnelsen vedrører en fremgangsmåte til fremstilling av vannfrie alkalikloroferrater(II,III) og deres anvendelse. The invention relates to a method for the production of anhydrous alkali chloroferrates (II, III) and their use.
Alkalikloroferrater(II,III) er forbindelser fraAlkali chloroferrates(II,III) are compounds from
systemet alkaliklorid/jern (II)klorid/jern(III)klorid. Alkaliklorof errater (II ) , f.eks. K2FeCl4og KFeCl3er kjent. De lar seg fremstille ved sammensmeltning av .-.tilsvarende mengder alkaliklorid med vannfritt jern(II)klorid (sml. f.eks. J.Amer.Chem.Soc. 79 (1957), side 6149). Vannfritt jern(II)klorid er imidlertid bare vanskelig tilgjengelig og er således et kostbart utgangsstoff. For teknisk anvendelsesformål, f.eks. i tegl- og leirvareindustrien kreves imidlertid større mengder billig dannede produkter. Disse kan ikke fåes på den angitte måte. the system alkali chloride/iron (II) chloride/iron (III) chloride. Alkali chloroforms (II), e.g. K2FeCl4 and KFeCl3 are known. They can be prepared by fusing corresponding amounts of alkali chloride with anhydrous iron(II) chloride (cf. e.g. J.Amer.Chem.Soc. 79 (1957), page 6149). However, anhydrous iron(II) chloride is only difficult to obtain and is thus an expensive starting material. For technical application purposes, e.g. in the brick and clay industry, however, larger quantities of cheaply formed products are required. These cannot be obtained in the manner indicated.
Det lettere tilgjengelige tetrahydrat av jern(II)The more readily available iron(II) tetrahydrate
klorid kan ikke benyttes til fremstilling av alkalikloroferrater(II) da det ved sammensmeltningen med alkaliklorider oppstår oksyklorider. Det er av samme grunn heller ikke mulig å fremstille vannfrie alkalikloroferrater(II) på våtkjemisk måte, f.eks. over tørking av det i og for seg kjente kaliumtetrakloroferrat(II)-dihydrat. chloride cannot be used for the production of alkali chloroferrates (II) as oxychlorides are formed upon fusion with alkali chlorides. For the same reason, it is also not possible to produce anhydrous alkali chloroferrates(II) in a wet chemical way, e.g. over drying the per se known potassium tetrachloroferrate(II) dihydrate.
Den oppgave som lå til grunn for oppfinnelsen besto derfor i å fremstille vannfritt alkalikloroferrat(II,III), The task that formed the basis of the invention therefore consisted of producing anhydrous alkali chloroferrate (II, III),
spesielt alkalikloroferrat(II) på enkel og økonomisk måte.especially alkali chloroferrate(II) in a simple and economical way.
Denne oppgave løses ved at alkaliklorider eller ammo-niumklorid oppsmeltes med vannfritt jern(III)klorid og jernpulver i det ønskede støkiometriske forhold. Det resulterende alkaliklorof errat (II, III) tilsvarer formel This task is solved by melting alkali chlorides or ammonium chloride with anhydrous iron(III) chloride and iron powder in the desired stoichiometric ratio. The resulting alkali chloroform (II, III) corresponds to formula
idet A betyr et alkalimetallion eller et ammoniumion, x betyr et tall fra 1 til 10, y betyr et tall fra null til 1 og z et tall fra where A means an alkali metal ion or an ammonium ion, x means a number from 1 to 10, y means a number from zero to 1 and z a number from
null til 1 og y og z er ikke samtidig null.zero to 1 and y and z are not simultaneously zero.
Som alkaliklorider kommer det fortrinnsvis i betrakt-ning natrium- og/eller kaliumklorid. Prinsipielt kan fremgangsmåten ifølge oppfinnelsen også gjennomføres med litium-, caesium-eller rubidiumklorid. Sodium and/or potassium chloride are preferably considered as alkali chlorides. In principle, the method according to the invention can also be carried out with lithium, cesium or rubidium chloride.
Jern(III)klorid er lett tilgjengelig i vannfri formIron(III) chloride is readily available in anhydrous form
ved klorering av jern.by chlorination of iron.
Ved gjennomføring av fremgangsmåten ifølge oppfinnel-When carrying out the method according to the invention
ser er det fordelaktig å blande alkaliklorider med jern(III)-klorid, og oppvarme blandingen til smeltning og deretter å tilsette jernpulveret. Det kan imidlertid også fra begynnelsen anvendes en blanding av de tre komponenter. Eksempelvis får man kalium-tetrakloroferrat(II), idet man sammensmelter en blanding av kaliumklorid, jern(III)klorid og jernpulver i praktisk talt støkio-metriske mengder. It is therefore advantageous to mix alkali chlorides with ferric chloride, heat the mixture until it melts and then add the iron powder. However, a mixture of the three components can also be used from the start. For example, potassium tetrachloroferrate(II) is obtained by fusing a mixture of potassium chloride, iron(III) chloride and iron powder in practically stoichiometric quantities.
De ved fremstillingen av alkalikloroferrater(II)Those in the production of alkali chloroferrates(II)
ved fremgangsmåten ifølge oppfinnelsen aktuelle temperaturer skal velges så høyt at etter avslutning av smelteprosessen foreligger en homogen smelte. Fortrinnsvis anvendes temperaturer fra 400 til 700°C. in the method according to the invention, the relevant temperatures must be chosen so high that after the end of the melting process a homogeneous melt is present. Temperatures from 400 to 700°C are preferably used.
Ved fremgangsmåten ifølge oppfinnelsen kan det fremstilles de fra litteraturen kjente alkalijernklorider, f.eks. K2FeCl4, KFeCl3, NaFeCl3, Na2FeCl4og Nal^FeClg. With the method according to the invention, the alkali iron chlorides known from the literature can be produced, e.g. K2FeCl4, KFeCl3, NaFeCl3, Na2FeCl4 and Nal^FeClg.
Det kan imidlertid også anvendes blandinger av disse forbindelser idet man endrer mengdeforholdet av utgangsstoffene alkaliklorid, jern(III)klorid og jernpulver. Eksempelvis kan en blanding med den formale., sammensetning KFeCl3. K2FeCl4fremstilles ved at man for komponentene kaliumklorid, jern(III)-klorid og jernpulver velger et molart mengdeforhold på 9 : 4 : 2. However, mixtures of these compounds can also be used by changing the quantity ratio of the starting materials alkali chloride, iron (III) chloride and iron powder. For example, a mixture with the formal., composition KFeCl3. K2FeCl4 is produced by choosing a molar quantity ratio of 9 : 4 : 2 for the components potassium chloride, iron(III) chloride and iron powder.
Ved fremgangsmåten ifølge oppfinnelsen er det videre mulig å fremstille alkalijernklorider som inneholder overskytende alkaliklorid, f.eks. av den formale sammensetning K2FeCl4 . 2KC1. Hertil går man frem ved fremgangsmåten ifølge oppfinnelsen således With the method according to the invention, it is also possible to produce alkali iron chlorides which contain excess alkali chloride, e.g. of the formal composition K2FeCl4. 2KC1. This is done by the method according to the invention as follows
at man for utgangsblandingen av KC1, FeCl3og jernpulver velger et molart mengdeforhold på 12 : 2 : 1. Man kan imidlertid også i første rekke fremstille en smelte av sammensetningen K2FeCl4og i denne å innføre den nødvendige mengde kaliumklorid. that for the initial mixture of KC1, FeCl3 and iron powder, a molar quantity ratio of 12 : 2 : 1 is chosen. However, one can also primarily prepare a melt of the composition K2FeCl4 and introduce the required amount of potassium chloride into this.
Det er videre mulig å fremstille blandet alkalijern-klorid, f.eks. slik med formel NaKFeCl4-. For dette formål anvender man som utgangsblanding f.eks. en blanding av 3 mol KC1, 3 mol NaCl, It is also possible to produce mixed alkali iron chloride, e.g. such with formula NaKFeCl4-. For this purpose, e.g. a mixture of 3 mol KC1, 3 mol NaCl,
2 mol FeCl-j og 1 mol jernpulver. På analog måte lar det seg også fremstille NaK^FeClg. Ved fremgangsmåten ifølge oppfinnelsen kan det også fremstilles alkalijernklorider, hvori jern samtidig er tilstede i to- og treverdig form. Hertil må mengden av det for reduksjon anvendte jern nedsettes tilsvarende. Man kan f.eks. fremstille produkter som har sammensetningen KFeCl^ . KFeCl^. Hertil be-nytter man en utgangsblanding som f.eks. består av 6 mol KCl, 5 mol FeCl3og 1 mol jernpulver. 2 mol FeCl-j and 1 mol iron powder. NaK^FeClg can also be prepared in an analogous way. By the method according to the invention, alkali iron chlorides can also be produced, in which iron is simultaneously present in divalent and trivalent form. In addition, the amount of iron used for reduction must be reduced accordingly. One can e.g. produce products that have the composition KFeCl^ . KFeCl^. For this, a starting mixture is used, e.g. consists of 6 mol KCl, 5 mol FeCl3 and 1 mol iron powder.
De hittil nevnte forbindelser er for det meste en-hetlig krystalliserende forbindelser. Det er imidlertid ved fremgangsmåten ifølge oppfinnelsen også mulig å fremstille hetero-gen krystalliserte blandinger av forskjellige alkalikloroferrater (II,III), idet man sammensmelter de tilsvarende mengder alkaliklorid, jern(III)klorid og jernpulver. Den dannede sammensetning lar seg beregne av den generelle formel II, hvori AC1 betyr alkaliklorid: The compounds mentioned so far are mostly single-crystallizing compounds. However, with the method according to the invention, it is also possible to prepare heterogeneous crystallized mixtures of different alkali chloroferrates (II, III), by fusing together the corresponding amounts of alkali chloride, iron (III) chloride and iron powder. The resulting composition can be calculated by the general formula II, in which AC1 means alkali chloride:
Ved omformning får man herav den generelle formel III hvorav det lett lar seg beregne hvilke deler av utgangsstoffene må anvendes for å få et sluttprodukt av ovennevnte sammensetning: By reformulation, the general formula III is obtained from this, from which it is easy to calculate which parts of the starting materials must be used to obtain a final product of the above-mentioned composition:
Fremstillingen av alkaliklorof errater (II}" III) ved fremgangsmåten ifølge oppfinnelsen kan foregå teknisk på fordelaktig måte i jernkar. Overraskende har detlvist seg at smeltens angrep på karets vegger ved nærvær av jernpulver er forholdsvis liten. The production of alkali chloroforms (II}" III) by the method according to the invention can take place technically in an advantageous manner in iron vessels. Surprisingly, it has been found that the attack of the melt on the walls of the vessel in the presence of iron powder is relatively small.
Etter gjennomføring av smeltereaksjonen kan man la smeiten f.eks. stivne i reaksjonskaret. Da den trekker seg sammen ved avkjøling, kan den etter stivning lett fjernes fra karet og etter behov knuses, f.eks. ved maling. Smeiten kan imidlertid også fjernes fra reaksjonskaret og f.eks. ved hjelp av en kjølevalse eller kjølesnekke på i og for seg kjent måte overføres i den faste form. After completion of the melting reaction, you can leave the smelting e.g. solidify in the reaction vessel. As it contracts on cooling, after solidification it can be easily removed from the vessel and crushed as needed, e.g. by painting. However, the smelt can also be removed from the reaction vessel and e.g. by means of a cooling roller or cooling screw in a manner known per se is transferred in the solid form.
Fremgangsmåten ifølge oppfinnelsen er en fordelaktig måte for å fremstille de hittil vanskelig tilgjengelige alkali kloroferrater(II) teknisk i stor målestokk og under anvendelse av billige råstoffer. De på denne måte frembragte produkter anvendes spesielt ved farving av kéramiske legemer ved påføring før brenning eller ved tilsetning under brenningen. The process according to the invention is an advantageous way to produce the hitherto difficult-to-access alkali chloroferrates (II) technically on a large scale and using cheap raw materials. The products produced in this way are used in particular for coloring ceramic bodies by application before firing or by addition during firing.
Fremgangsmåten ifølge oppfinnelsen skal forklaresThe method according to the invention shall be explained
ved hjelp av noen eksempler.with the help of some examples.

Nu stoppes oppvarmingen og beholderinnholdet avkjøles. Den av-kjølte smelte danner en grå krystallinsk masse som lett lar seg fjerne fra beholderen. Den har praktisk talt den støkiometriske sammensetning KFeCl^. Utbyttet utgjør 100 kg (0,497 kmol). Now the heating is stopped and the contents of the container are cooled. The cooled melt forms a gray crystalline mass which can be easily removed from the container. It practically has the stoichiometric composition KFeCl^. The yield amounts to 100 kg (0.497 kmol).
