Abstract
The present invention relates to a microfluidic flow process for making monomers, monomers made by such processes, and methods of using such monomers. In such process, microfluidic reaction technology is used to synthesize cyanation reaction products orders of magnitude faster than is possible in batch and continuous syntheses. The aforementioned process does require strictly regulated, highly toxic cyanogen chloride. Thus the aforementioned process is more economically efficient and reduces the environmental impact of thermosetting resin monomer production, and produces thermosetting resin monomers in greater purity than obtained through typical processes.
Claims17
A process of making a monomer;
- said process comprising processing, in a microfluidic reactor the following materials:
- a) a multifunctional phenol;
- b) at least one cyanogen halide;
- and
- c) a base selected from the group consisting of an organic base, an inorganic base and mixtures thereof;
- at a temperature of from about −78° C. to about 25° C., said materials having residence time of from about 0.1 seconds to about 600 seconds.
