IONIC LIQUIDS HAVING SILOXANE FRAGMENT IN CATION AS HEAT CARRIERS

摘要

FIELD: chemistry.;SUBSTANCE: disclosed are ionic liquids of general formula where R = alkyl or phenyl; X = 1,2-dimethylimidazolium, N-methylpyrrolidinium or trialkylammonium, as heat carriers.;EFFECT: disclosed ionic liquids have lower saturated vapour pressure in the region of high temperatures compared to other existing heat carriers, which ensures their explosion safety and considerably low volatility in dynamic vacuum and open space conditions.;1 tbl, 4 ex
