摘要:离子液体(ils)被标记为一种有前途的绿色替代传统材料的方法.但是,已发现许多il,特别是疏水性il(hil)具有毒性.Hil的结构多样性有限,因为大多数hil由具有长烷基链并与[bf 4 ],[pf 6 ]或[ntf 2 ]阴离子配对的杂芳族阳离子组成.这项研究旨在通过合成两组具有独特阳离子和阴离子的hil来使hil多样化.第一组hil包含与[ntf 2]阴离子.[dc-醚]阳离子被鉴定为有前途的阳离子,并与一系列不对称双(磺酰基)酰胺阴离子配对以形成第二组hil.总共合成了20个hil.每个hil均使用传统的物理化学技术进行表征,并使用体外和体内方法评估其毒性.

标 题:Synthesis of copper phthalocyanine using deep eutectic solvent
发明人：SHANKARLING G S; JOGLEKAR AMRUTA R
权利人:SHANKARLING G S
摘要:The present disclosure generally relates to synthesis of copper phthalocyanine. In particular, the present disclosure relates to a method of synthesis of copper phthalocyanine using deep eutectic solvent (DES), which can be carried out at low temperature, does not involve use of high boiling solvents, uses less urea and allows solvents used in the process to be recycled.

摘要:A method for direct synthesis of cyclic carbonates is achieved by reacting at least one epoxide with carbon dioxide in the presence of a choline catalyst, such as choline chloride, under mild conditions such as a temperature between about 25° C. to 150° C. and a pressure of from about atmospheric to 75 psi (0.52 MPa), in a cyclic carbonate solvent. The choline catalyst may be the only catalyst used, and a co-catalyst or hydrogen bond donor is not necessary. The concentration of choline catalyst in the solvent ranges from about 0.5 mol % to about 10 mol %, based on the epoxide.
