Claims (7)
1. Förfarande för separering av en första mättad fettsyra frän en andra mättad fettsyra, som ingär i en chargeblandning bestäende av dessa syror, viikon första mättad fettsyra är minst tvä kolatomer större än den andra mättade fettsyran, kännetecknat av att nämnda chargeblandningen bringas under adsorptionsbetingelser i kontakt med eilikalit, varvid den nämnda första mättade fettsyran adsorberas selektivt, resten av chargeblandningen avlägsnas frän adsorptionsmedlet och den nämnda första mättade fettsyran ätervinns frän adaorptions-medlet genom desorption under desorptionsbetingelser medelst deeorptionsväteka, som är löslig i chargeblandningen och vara polaritetsindex är minst 3,5.
2. Förfarande enligt patentkravet 1, kännetecknat av att de nämnda adsorptions- och desorptionsbetingelserna όπιό fattar en temperatur mollan c. 20 och 200 C och ett till-räckligt tryck för upprätthällande av en vätekefas.
3. Förfarande enligt patentkravet 1, kännetecknat av att den nämnda första mättade fettsyran bestär av myristinsyra och den nämnda andra mättade fettsyran bestär av laurinsyra.
4. Förfarande enligt patentkravet 1, kännetecknat av att nämnda process utförs med ett eimulerat rörandeskikt-strömningssystem.
