| titleOfInvention | Preparation method of Novel asymmetric quaternary amine ionic liquid and products thereof and application |
| abstract | The invention discloses preparation methods of a kind of Novel asymmetric quaternary amine ionic liquid and products thereof and application, wherein method includes, triethylamine or tripropyl amine (TPA) and acetonitrile are mixed, bromo-hydrocarbons is added thereto again, 20~28h is stirred to react at 80~100 DEG C, 300~800rpm, after revolving, freeze-drying obtains asymmetric quaternary amine halogeno salt at -40~-30 DEG C；Potassium acetate is added to asymmetric quaternary amine halogeno salt, adds anhydrous methanol or dehydrated alcohol, is stirred to react 20~28h under the conditions of 25~45 DEG C, 300~600rpm, filtering, filtrate is rotated, is freeze-dried at -40~-30 DEG C, asymmetric quaternary amine ionic liquid product is obtained.The present invention provides a kind of methods for preparing Novel asymmetric quaternary amine ionic liquid, and ionic liquid and cosolvent are mixed for dissolve cellulose, and preparation method is simple, mild condition, solvent easily recycle, are at low cost.In addition, dissolution cellulose is had excellent performance after the ionic liquid being prepared is mixed with cosolvent. |
