Abstract
The invention concerns fusible mixtures of high electroconductivity which consist of (a) 0.5 to 99% by weight, relative to the total weight of the mixture, of a TCNQ complex of the formula ##STR1## in which R and R.sub.1 independently of each other stand for an optionally substituted aliphatic, cycloaliphatic or araliphatic radical having 1 to 30 C atoms and n is 1, 2 or 3 or a fraction between these numbers and (b) 99.5 to 1% by weight, relative to the total weight of the mixture, of one or more special liquid organic compounds.
Claims3
A fusible mixture of high electroconductivity consisting of
- (a) 0.5 to 99% by weight, relative to the total weight of the mixture, of a TCNQ complex of the formula ##STR6## in which R and R.sub.1 independently of each other stand for an optionally substituted aliphatic, cycloaliphatic or araliphatic radical having 1 to 30 C atoms and
- n is 1, 2 or 3 or any fraction between these numbers and
- (b) 99.5 to 1% by weight, relative to the total weight of the mixture of one or more of the following liquid organic compounds:
- N-methylpyrrolidone, N-methylcaprolactam, .gamma.-butyrolactone, caprolactone, dipentyl ether, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, 1,4,7,10,13-pentaoxacyclopentadecane, 1,4,7,10-tetraoxacyclododecane, dimethyl sulphoxide, diethyl sulphoxide, tetramethylene sulphone tetramethylurea and/or propylene carbonate.
