Abstract
Inventia se refera la derivati ai carbazolului, caracterizati prin aceea ca au structura cu formula generala I : (vezi form. in desc.) în care R este CH2=CR-, cînd R' este H, CH3 sau este un radical alchil C1-C20 si sunt substante solide cristaline cu temperatura de topire 130....213 degree C. Procedeul de preparare a lor consta în aceea ca se trateaza carbazolul cu metilolacrilamida, metilolmetacrilamida metilolalchil-(C1-20) -amode alcanolamide, într-un solvent ales dintre ester de petrol în amestec cu benzen sau toluen sau metiletilcetona în amestec cu benzen toluen sau tetraclorurî de carbon, eventual în prezenta metocidului sau etoxidului de sodiu la temperatura de reflux timp de 6...12 h.The invention relates to carbazole derivatives, characterized in that they have the structure of the general formula I wherein R is CH 2 = CR-, where R 1 is H, CH 3 or is a C 1 -C 6 alkyl radical, C20 and are crystalline solids having a melting point of 130 DEG-213 DEG C. The process for their preparation consists in treating the carbazole with methylolacrilamide, methylolmethacrylamide, methylolalkyl (C1-20) -amodecalcanolamides, in a solvent selected from petroleum ester in admixture with benzene or toluene or methyl ethyl ketone in admixture with benzene toluene or carbon tetrachloride, optionally in the presence of sodium methoxide or sodium ethoxide at reflux temperature for 6-12 hours.
