Abstract
Pronalazak se odnosi na poboljšani postupak za proizvodnju diestara 2,3,5-trimetil-hidrohinona pretvaranjem 2,6,6-trimetilcikloheks-2-en-1,4-diona (4-okso-izoforona, ketoizoforona) u prisustvu jednog rastvorenog, kiselog katalizatora i jednog sredstva za aciliranje, kao na pr. anhidrida karbonske kiseline ili halogenida karbonske kiseline. Diestar 2,3,5-trimetilhidrohinona može se, u datom slučaju, posle toga prevesti saponifikacijom u slobodan 2,3,5-trimetilhidrohinon (TMHQ), koji je vredan sastojak u sintezi vitamina E.[This invention refers to the improved procedure for the production of 2, 3, 5 -trimethylhydrochinondiesters with transformation of 2.6.6-trimethylcycloheks-2-en 1.4 diones (4-oxo-isoforones, ketoisoforones) in the presence of one dissolved, acid katalyst and one means for acilation, for example unhydrides of carbonic acid or halogenides of carbon acid. Diesther of 2.3.5 trimethylhydrochinon, can, in this concrete case, be later translated by saponification in free 2.3.5 trimethylhydrochinon (TMHQ), that is valuable additive in the synthesis of vitamin E.
