| titleOfInvention | A kind of resin-carried anionic acid ionic-liquid catalyst and its application |
| abstract | The invention discloses a kind of resin-carried anionic acid ionic-liquid catalyst, which is prepared via a method which：Storng-acid cation exchange resin is scattered in toluene, zwitterionic compound is added, is reacted 12 ~ 24 hours at 80 ~ 100 DEG C；It filters after reaction, then filter cake dichloromethane is extracted at 40 ~ 50 DEG C, be then dried in vacuo 12 ~ 24 hours at 60 ~ 80 DEG C.The present invention is using the storng-acid cation exchange resin with sulfonic acid group as counter-anion, prepare load anionic acidic ion liquid, preparation process is simple and practicable, it is i.e. recyclable through filtering or centrifuging after reaction, reaction cost is reduced, is to realize ionic liquid loaded effective ways.The invention also discloses application of the catalyst in Prins condensation reactions, acetal (ketone) react and prepare polyoxymethylene dialkyl ether reaction, and excellent catalytic effect, dosage is low and recycling is convenient. |
