Mechanochemical synthesis of radiographic agents intermediates
The present invention generally relates to a process using a mechanochemical approach exploiting the mechanical milling of reactants for the manufacturing of acetyl Iopamidol and, more generally, of key intermediates of radiographic contrast agents, and of the contrast agents themselves.
Ionic liquid composition and method for dissolving cellulose using the same
The present invention provides an ionic liquid composition containing an ionic liquid and water. The ionic liquid composition does not contain an enzyme capable of hydrolyzing cellulose. The ionic liquid is represented by the following chemical formula (I): [(CH.sub.3).sub.3N(CH.sub.2).sub.2OH].sup.+[NH.sub.2-L-CHNH.sub.2COO].sup. (I); where L is absent or a linker. A molar ratio of [(CH.sub.3).sub.3N(CH.sub.2).sub.2OH].sup.+ to [NH.sub.2-L-CHNH.sub.2COO].sup. is not less than 0.87 and not more than 1.14. A weight ratio of the water to the ionic liquid composition is not more than 7.3%. The present invention provides an ionic liquid composition capable of dissolving cellulose without a cellulose-degrading enzyme, namely, an enzyme capable of hydrolyzing cellulose.
