The solubilities of 4-amino-4'-nitrodiphenyl sulfide in n-butanol, ethyl acetate, chlorobenzene, toluene, dichloromethane, and chloroform were determined between 287.45 K and 365.55 K (p = 0.1 MPa) using a laser monitoring dynamic technique and synthetic method. The solubilities determined were well-correlated with the modified Apelblat equation with the mean relative deviation (sigma) no more than 1.27 % and the root-mean-square deviation (rmsd) no more than 0.07
