PROCESS FOR PREPARING IMIDAZOLIUM BASED IONIC LIQUIDS WITH DI-POLYMERIZED OXIRANE BASE.

摘要

The present invention relates to a process of synthesis of certain ionic liquids di-polymerized based Radziszewsky type reaction, whereby primary amines containing at least one terminal functional group, for example ùOH, aldehydes and a mineral or organic acid, react exothermically in a single step, thus resulting in an ionic liquid by condensation, then oxirane derivative molar quantities are added, by controlling the temperature and pressure a di-polymerized ionic liquid is obtained. The process of the present invention is advantageous because it provides a synthesis scheme for di-polymerized ionic liquids, primarily using short reaction times and high performance; this process can be further scaled for industrial production and it can accept alternative chemical precursors of lower cost.
