Abstract

Przedmiotem zgłoszenia jest sposób syntezy cyklicznych ketali, o strukturze przedstawionej na wzorze ogólnym 1, w którym poszczególne podstawniki R<sup>1</sup>, R<sup>2</sup>, R<sup>3</sup>, R<sup>4</sup> oznaczają niezależnie od siebie atom wodoru lub grupę metylową lub grupę etylową, polegający na tym, że do reaktora wprowadza się heterogeniczny fotokatalizator, polialkohol oraz keton, dobierając ilości składników tak, by stężenie masowe fotokatalizatora w mieszaninie reakcyjnej mieściło się w zakresie od 0,25 mg/mL do 4,2 mg/mL, natomiast stosunek molowy polialkoholu do ketonu był równomolowy lub korzystniej z nadmiarem ketonu, przy czym: - jako fotokatalizator stosuje się katalizator w postaci nośnika katalitycznego z dwutlenku tytanu z naniesioną na nim warstwą aktywną nanocząstek rutenu, a opcjonalnie również nanocząstek wanadu lub molibdenu lub wolframu, przy czym zawartość nanocząstek warstwy aktywnej w masie całego fotokatalizatora wynosi od 0,01% wag. do 10% wag., - jako polialkohol stosuje się poliol wybrany spośród: 1,2-propanodiol lub 1,2-etanodiol, - jako keton stosuje się aceton lub 2-butanon lub 3-pentanon, następnie reaktor zamyka się, po czym doprowadza się do zawieszenia fotokatalizatora w mieszaninie reakcyjnej poddając mieszaninę reakcyjną sonikacji ultradźwiękami, a w kolejnym etapie mieszaninę reakcyjną poddaje się działaniu temperatury o wartości od 25 do 70°C, w czasie od ≥1 minuty do 100 minut, następnie oddziela się fotokatalizator, korzystnie przez dekantację i wirowanie, a z otrzymanej mieszaniny poreakcyjnej, znanym sposobem od produktów ubocznych stanowiących pośrednie produkty niedomknięcia pierścienia oddziela się produkty główne w postaci wybranych cyklicznych ketali.
