Process for preparing imidazolium based ionic liquids with di-polymerized oxirane base

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 OH, 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. An example of the general synthesis scheme of ionic liquids-propoxylated di (LI's) imidazolium follows: ##STR00001## Whereby an efficiency greater than 96% of propoxylated ionic liquid is obtained, the product characterized by spectroscopic data.

SEPARATION OF ORGANIC ACIDS FROM MIXTURES CONTAINING AMMONIUM SALTS OF ORGANIC ACIDS
20180162797 · 2018-06-14 ·

The invention relates to a process for separation of organic acids from mixture of ammonium salts of one or more organic acids and other compounds via an integrated process. The process involves suspending mixture of ammonium salts of one or more organic acids and other compounds in dry hydrocarbon solvent/s or mixtures thereof; wherein the selected hydrocarbon solvent/s or mixtures thereof have boiling point more than 100 C. and forms an azeotrope with water. The reaction mixture thus obtained is dehydrated azeotropically followed by esterification of basic salt of the organic acids by addition of alcohol in presence of metal or metal salt; thereafter the individual esters formed are separated by distillation and hydrolysed to obtain corresponding organic acids having more than 98% purity.
