Abstract

Спосіб одержання 1,1,1,2-тетрафторетану шляхом взаємодії в газовій фазі трихлоретилену і фтористоводневої кислоти при підвищеній температурі у присутності каталізатора - оксиду хрому, нанесеного на фторид алюмінію. Трихлоретилен піддають взаємодії з фтористоводневою кислотою в суміші з 1,1,1-трифторхлоретаном при 330 – 380 °C, при молярному співвідношенні трихлоретилену 1,1,1-трифторхлоретан 0,09 - 0,35, при молярному співвідношенні фтористоводневої кислоти і суми органічних продуктів 3 - 10 : 1, при часі контакту 2,6 - 20с. Каталізатор оксид хрому використовують у вигляді оксиду тривалентного хрому.
