Description
Vynález sa týká novej zlúčeniny 1-fenyl-2-[-4/2-hydroxyetoxy/fenyl}-1 ,2-etándiónu vzorca I co-co
CHj—CHj—OH /1/ a sposobu jej přípravy.
Spčsob přípravy novej zlúčeniny, ktorá je známa z literatúry, je založený na tom, že 1-hydroxy-2-^/4-fenyl-acetyl/-fenoxyJ-etán vzorca II (2^-CH2-CO-^O^-O-CH2- ch2-oh /11/ sa oxiduje kysličníkom seleničitým v prostředí vodného dioxánu pri refluxe.
Uvedená zlúčenina je medziprodukt syntézy polyméru so špeciálnym používáním.
Příklad mól 1-hydroxy-2-f/4-fenylacety 1/fenoxyJ-etánu sa rozpustí v dioxáne a přidá sa k němu roztok 1,1 molu kyslíčníka seleničitého, 1^1 molu vody v dioxáne a zmes sa refluxuje 5 až 8 hodin. Po tomto čase sa reakčná zmes přefiltruje, dioxán sa vákuovo odpaří a produkt sa krystalizuje z etanolu. Získá sa žitá krystalická látka o t.t. 104,5-105,5,°C a výtažok je 42Z.
