Fremgangsmåte for å redusere koksalts (uatriumklorids) Procedure for reducing common salt (non-sodium chloride)
tendens til sammenbaking. tendency to caking.
Foreliggende oppfinnelse vedrører en The present invention relates to a
fremgangsmåte for behandling av koksalt (natriumklorid) for å redusere dets tendens til å sammenbake og oppfinnelsen tilveiebringer også en fobedret form av koksalt som har liten eller ingen tendens til sammenbaking. method for treating common salt (sodium chloride) to reduce its tendency to caking and the invention also provides an improved form of common salt which has little or no tendency to caking.
Det er alminnelig kjent at koksalt har It is common knowledge that table salt has
en tendens til å sammenbake når det lag-res, og denne sammenbaking økes ofte av den tendens til gjentatt krystallisering som forekommer, hvis salt utsettes for vekslen-de høye og lave atmosfæriske fuktighets-forhold. a tendency to caking when stored, and this caking is often increased by the tendency to repeated crystallization which occurs if salt is exposed to alternating high and low atmospheric moisture conditions.
Et stort antall av fremgangsmåter er A large number of procedures are
blitt foreslått for å motvirke denne sammenbakingstendens og blant de mange materialer som anvendes ved disse fremgangsmåter, er vann-absorberende forbindelser, som påføres eller blandes med saltkornene eller krystallene. Slike vannabsorberende forbindelser kan være oppløselige eller uoppløselige. De vannoppløselige materialer, som f. eks. kalsiumklorid har en tendens til å gjøre saltet fuktig og klebrig. De vannuoppløselige forbindelser, som svakt have been proposed to counteract this caking tendency and among the many materials used in these processes are water-absorbing compounds which are applied or mixed with the salt grains or crystals. Such water-absorbing compounds may be soluble or insoluble. The water-soluble materials, such as e.g. calcium chloride tends to make the salt moist and sticky. The water-insoluble compounds, which weakly
basisk magnesiumcarbonat, gir uklare opp-løsninger når saltet oppløses i vann. Andre fremgangsmåter som har til oppgave å til-veiebringe en ugjennnomtrengelig film på saltkrystallene, f. eks. slike som omfatter bruken av aluminiumstearat og forskjellige oljer, er beheftet med den ulempen at de medfører reduserte oppløsningshastigheter for saltet med herav følgende nedsettelse av saltsmaken av krystallene. basic magnesium carbonate, gives cloudy solutions when the salt dissolves in water. Other methods which have the task of providing an impermeable film on the salt crystals, e.g. such as include the use of aluminum stearate and various oils, are affected by the disadvantage that they entail reduced dissolution rates for the salt with the consequent reduction in the salty taste of the crystals.
Ved alle de fremgangsmåter som an-vender de foran nevnte materialer, kreves det videre en forholdsvis stor mengde av materiale i forhold til mengden av salt som behandles for å kunne motvirke saltets sammenbakingstendens. In all the methods that use the above-mentioned materials, a relatively large amount of material is also required in relation to the amount of salt being treated in order to counteract the salt's tendency to stick together.
Det er også blitt anvendt ved fremstilling av salt med redusert sammenbakingstendens forbindelser som inneholder kom-plekse ioner f. eks. kaliumferrocyanid. Slike forbindelser kan anvendes effektivt ved lave konsentrasjoner, idet de kan reagere under svakt sure forhold med oppløselige jernsalter så at det dannes sterkt fargete uoppløselige forbindelser, f. eks. prøyssisk blått. Selv ved de lave konsentrasjoner som anvendes, kan dette medføre at det fåes et farget salt som er uønsket for mange øye-med. It has also been used in the production of salt with a reduced caking tendency of compounds containing complex ions, e.g. potassium ferrocyanide. Such compounds can be used effectively at low concentrations, as they can react under slightly acidic conditions with soluble iron salts so that strongly colored insoluble compounds are formed, e.g. Prussian blue. Even at the low concentrations used, this can result in a colored salt being obtained which is undesirable for many eyes.
Det har nu vist seg at sammenbakings-tendensen til natriumklorid kan reduseres betraktelig ved en fremgangsmåte i hen-hold til foreliggende oppfinnelse som be-står i at det til det faste salt tilsettes nitriltriacetamid med formelen N(CH2CONH2).i. It has now been shown that the caking tendency of sodium chloride can be considerably reduced by a method according to the present invention which consists in adding nitrile triacetamide of the formula N(CH2CONH2).i to the solid salt.
Den foretrukne mengde av nitriltriacetamid som anvendes, er mellom 0,05 og 0,0001 vektsprosent av det faste nartium-klorid. Nitriltriacetamid kan også anvendes i forbindelse med kjente anti-bakningstil-setninger. The preferred amount of nitrile triacetamide used is between 0.05 and 0.0001 weight percent of the solid nartium chloride. Nitrile triacetamide can also be used in connection with known anti-caking additives.
Foreliggende oppfinnelse tilveiebringer i overensstemmelse med det anførte en forbedret form for koksalt som har liten eller ingen tendens til sammenbaking og som inneholder nitriltriacetamid som for-trinnsvis er godt dispergert i hele massen av saltkrystaller. The present invention provides, in accordance with the above, an improved form of table salt which has little or no tendency to caking and which contains nitrile triacetamide which is preferably well dispersed throughout the mass of salt crystals.
Nitriltriacetamidet kan tilsettes til saltet på en hvilken som helst hensiktsmessig måte, skjønt det er fordelaktig å sikre at fordelingen er så jevn som mulig i.hele salt-massen. Da forbindelsen er lett oppløselig i vann, kan den utsprøytes i form av en fortynnet oppløsning på det tørre faste salt. Det kan også tilsettes til fuktig salt etter fraskillelse fra moderluten eller en oppløsning av den kan blandes med sus-pensjonen av fast natriumklorid i dets mo-derlut under saltfremstillingsprosessen. The nitrile triacetamide can be added to the salt in any suitable manner, although it is advantageous to ensure that the distribution is as uniform as possible throughout the salt mass. As the compound is easily soluble in water, it can be sprayed in the form of a dilute solution onto the dry solid salt. It can also be added to moist salt after separation from the mother liquor or a solution of it can be mixed with the suspension of solid sodium chloride in its mother liquor during the salt making process.
Den ønskete mengde av tilsetnings-midlet som skal brukes beror på kornstør-relsen og følgelig overflatearealet av saltkrystallene som skal behandles. Den foretrukne konsentrasjon for vanlig inndam-pet finsalt av en partikkelstørrelse av ca. 0,3 mm er 0,001 vektsprosent. The desired quantity of the additive to be used depends on the grain size and consequently the surface area of the salt crystals to be treated. The preferred concentration for ordinary evaporated fine salt of a particle size of approx. 0.3 mm is 0.001% by weight.
Foreliggende oppfinnelse tilveiebringer et produkt og en fremgangsmåte for dets fremstilling som oppviser den fordel at det fåes en varig motvirkning av sammenba-kingstendensen under bruk av en stabil ikke-ionisk forbindelse ved ekstremt lave konsentrasjoner som ikke medfører noen fargning av saltet, når dette utsettes for visse av de lagringsforhold som ofte forekommer. Ytterligere fordeler er at den til-satte forbindelse er oppløselig slik at det behandlete salt gir en klar oppløsning og forurensningen av saltet er ubetydelig da mengden av det anvendte tilsetningsmid-del er meget liten. The present invention provides a product and a method for its production which exhibits the advantage that a permanent counteraction of the caking tendency is obtained using a stable non-ionic compound at extremely low concentrations which does not cause any coloring of the salt, when it is exposed to certain of the storage conditions that often occur. Further advantages are that the added compound is soluble so that the treated salt gives a clear solution and the contamination of the salt is negligible as the amount of the additive used is very small.
Eksempel 1: Tørt knust stensalt med en partikkel-størrelse av ca. 2,5 mm ble påsprøytet en fortynnet oppløsning av nitriltriacetamid i vann for å gi et materiale som inneholdt 1,5 % fuktighet og 0,001 % nitriltriacetamid basert på vekten av saltet. Man lot saltet få henligge utsatt for luften uten-dørs i en uke, sammen med en prøve behandlet med lignende mengde fuktighet, men uten noe nitriltriacetamid. Det be-handlede salt sammenbakte ikke, mens det ubehandlede salt ble utsatt for en hård sammenbaking. Eksempel 2: 50 tonn vakuumsalt ble etter fraskillelse fra moderluten på et filter, men som fremdeles inneholdt 4 % saltoppløsning, påsprøytet med 0,45 kg nitriltriacetamid oppløst i 45 kg vann og saltet ble derpå tørket i en varmluftstørker. Saltet som man fikk fra denne behandling, sammenbakte ikke når det ble lagret under forskjellige ugunstige atmosfæriske forhold. En lignende saltcharge som ble behandlet på samme måte, men som ikke var behandlet med nitriltriacetamid, ga et salt som, når det ble lagret under de samme forhoid, gikk over til hårde klumper. Example 1: Dry crushed rock salt with a particle size of approx. 2.5 mm was sprayed with a dilute solution of nitrile triacetamide in water to give a material containing 1.5% moisture and 0.001% nitrile triacetamide based on the weight of the salt. The salt was left exposed to the air outdoors for a week, along with a sample treated with a similar amount of moisture but without any nitrile triacetamide. The treated salt did not stick, while the untreated salt was exposed to a hard stick. Example 2: 50 tonnes of vacuum salt were, after separation from the mother liquor on a filter, but which still contained 4% salt solution, sprayed with 0.45 kg of nitrile triacetamide dissolved in 45 kg of water and the salt was then dried in a hot air dryer. The salt obtained from this treatment did not cake when stored under various adverse atmospheric conditions. A similar charge of salt treated in the same manner but not treated with nitrile triacetamide gave a salt which, when stored under the same conditions, turned into hard lumps.
