The present invention is concerned with the formation of amide bonds. More specifica lly, the present invention, relates to processes for the manufacture of organogellant compounds (OG) as depicted below wherein L is selected from C2-C20 alkyl, C6-C20 aryl, C7-C20 alkylaryl, R1 are side chain substituents and one of X1, X2 is nitrogen and the other two are carbon. Processes of the present invention employ reaction mixtures with beneficial flow characteristics allowing sufficient agitation of all parts of these reaction mixtures and thus achieving adequate mixing of reaction partners and/or dissipation of heat. The beneficial flow characteristics are achieved by using suitable activation for coupling the terminal pyridine-carboxylic acid.
本发明涉及酰胺键的形成。更具体地,本发明涉及制备有机凝胶剂化合物(OG)的工艺,其中L选自C2-C20烷基,C6-C20芳基,C7-C20烷基芳基,R1是侧链取代基,X1、X2中的一个是氮,另一个是碳。本发明的工艺利用具有良好流动特性的反应混合物,允许充分搅拌这些反应混合物的所有部分,从而实现反应物的充分混合和/或散热。通过使用适当的活化剂耦合末端吡啶羧酸,实现了这些有益的流动特性。
