Abstract

Postupak za proizvodnju acetata α-tokoferola u kružnom postupku kondenzacijom diestara trimetilhidrohinona i izofitola u prisustvu jednog katalizatorskog sistema, koji se sastoji od jednog halogenida cinka i jedne vodene protonske kiseline i, u datom slučaju, jednog elementarnog metala, u jednoj smeši rastvarača / vode, koja se može ekstrahovati ili mešati sa vodom i posle toga vraćanja katalizatorskog sistema.[A method for acetate α-tocopherol production in the cyclic process by condensation of diesters trimethylhydroquinone and isophytole in the presence of one catalyst system, that comprises one halogen zinc and one water protonic acid, in the given case, one element metal, in one solvent mixture/ water, that can be extracted or mixed with water and upon that restoring the catalyst system.
