摘要

NEW MATERIAL:The compound of formula l [R is 1-6C alkyl; m is positive number corresponding to the molar number of neutral 7,7,8,8- tetracyanoquinodimethane (hereinafter abbreviated as TCNQ) included in 1mol of the complex salt and is 0.5-1.5]. EXAMPLE:S-methyl-acetophenone isosemicarbazone.quaternary ammonium.TCNQ complex salt. USE:Useful as a solid electrolyte for solid electrolytic capacitor. etc. The capacitor is composed of a pair of aluminum foils wound round in a state separated from each other with separators or composed of a capacitor element consisting of sintered tantalum powder. PREPARATION:The compound of formula I can be produced by reacting an S-substituted-acetophenone isosemicarbazone.quaternary ammonium salt of formula II (X is halogen) with TCNQ of formula III.
