Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania materiału zmiennofazowego charakteryzujący się tym, że kwas winowy poddaje się reakcji z alkoholem w obecności 1% - 100% molowych protycznej cieczy jonowej, przy stosunku molowym alkoholu do kwasu od 1:1 do 20:1 w stosunku do kwasu winowego, przy czym reakcję prowadzi się w temperaturze 20°C - 100°C w czasie od 5 min do 40 h, następnie po zakończeniu reakcji do mieszaniny dodaje się rozpuszczalnik organiczny i wodę, a następnie rozdziela się warstwę organiczną, w której zawarty jest ester oraz nieprzereagowany alkohol i oddestylowuje się rozpuszczalniki, następnie fazę organiczną odparowuje się, a otrzymany ester kwasu winowego rekrystalizuje się z rozpuszczalnika organicznego do otrzymania czystego produktu, a z fazy wodnej oddestylowuje się wodę, a otrzymaną ciecz jonową ponownie wykorzystuje się w procesie. Przedmiotem zgłoszenia jest także ester kwasu winowego.
