The idea in this study is to form gas hydrate of hydrochlorofluorocarbon HCFC-141b from its O/W emulsion

with OP-10 or SDS as emulsifying reagent

and the programmed cooling experiments were carried out in a controllable air conditioning chamber.The results showed that under static state emulsions containing different contents of HCFC-141b could form hydrates at a temperature above -5℃

with random induction time and fluctuating initiation temperature of hydrate formation.The results also showed that

before and after hydrate formation

the reaction system was iced over

and adding ice particles could induce rapid formation of hydrate.The emulsion from dissociation

by re-emulsification，could form hydrate at a temperature above freezing point within 1 h because of the “memory” effect.
