Abstract

The present invention is directed to the field of substituted tetrazole synthesis and manufacture. More particularly, the present invention is directed to processes for preparing substituted tetrazoles and tetrazolate salts, such as sodium nitrotetrazolate and sodium cyanotetrazolate, using small scale and/or microreactor techniques. The use of the present techniques result in less hazardous and more efficient manufacturing processes.
