Abstract

Изобретение относится к способу получения 1,1,1,2-тетрафторэтана (HFC-134а). В первом реакторе происходит взаимодействие 1,1,1-трифтор-2-хлорэтана (HCFC-133a) и фтористого водорода. Продукт, образующийся на первой стадии реакции, подают во второй реактор вместе с трихлорэтиленом и фтористым водородом. Вторая реакция осуществляется при более высокой температуре, чем первая. Можно до удаления сырого HFC-134a удалять HCl. Непрореагировавшие HCFC-133a, трихлорэтилен и фтористый водород можно возвращать в цикл в первый реактор.Международная заявка была опубликована вместе с отчетом о международном поиске.
