Functionalized alkaline ionic liquid gemini-type and a method for preparing functionalized alkaline ionic liquid base gemini-type

摘要

the subject of the invention is funkcjonalizowana alkaline ion liquid type geminid model 1 and receiving funkcjonalizowanej alkaline ionic liquid type geminid, which lies in the fact that the n - and metyloimidazol dibromide neopentylowy in proportion as the molar 2,05 - 2.1: 1 is mixed in temperat urze 140 - 160u00b0c until zestalenia content reactor, followed by 2 - 4 hours.the resulting solid product is cooled, washed several times with small portions of acetonitrile and the purified sludge dibromku dried, after which dissolves in the solution and alcohol containing koh in a proportion of 1 mol koh per mole of br, the hydroalcoholic solution contains 5 to 20 parts of weight of water and 80 to 95 parts by weight of alcohol,the suspension is mixed by 16 - 24 hours at a temperature of 25 - 105. then the separated sludge kbr is filtered, and a clear solution is concentrated under reduced pressure to obtain the ionic liquids of the formula 1.
