Abstract

(Solid + liquid) phase diagrams have been determined for (N -methyl-2-pyrrolidinone + benzene, or toluene, or 1,3,5-trimethylbenzene, or ethylbenzene, or chlorobenzene, or 1,2-dichlorobenzene, or 1,2,4-trichlorobenzene, or 1,1,1-trichloroethane, or dichloromethane). Solid addition compounds form with the empirical formulae: \ (C5H9NO)2· C6H6\, (C5H9NO · 2ClC6H5),(C5H6NO · Cl2C6H4) ,(2C5H9NO · Cl3C6H3) . All are congruently melting compounds. Compound formation is attributed to a charge-transfer interaction with the benzene, or chlorobenzene, or 1,2-dichlorobenzene, or 1,2,4-trichlorobenzene acting as electron acceptors and the nitrogen, or oxygen in N -methyl-2-pyrrolidinone acting as electron donors.
