Abstract
Ovaj pronalazak odnosi se na proces za proizvodnju α-tokoferol acetata u recirkulacionom procesu kondenzovanjem trimetilhidrohinona i izofitola u prisustvu katalitičkog sistema koji se sastoji od zink halogenida i vodene protonske kiseline i po slobodnom izboru elementarnog metala u smeši polarni rastvarač/voda a koja je ekstraktibilna ili mešljiva sa vodom i naknadna acilacija rezultujućeg α-tokoferola i recirkulacija katalitičkog sistema.[This invention relates to the production process of α-tocopherol acetates in recycling process by condensation of trimethylhydroquinone and isophytole with presence of catalyst system that comprises zinc halogenide and water protonic acid and according to its own choice of primary metal in mixture, a polar solvent/water which is extractible or mixable with water and additional acilation of resulting α-tocopherol and recycling catalyst system.
