Abstract
The adductive crystals formed by trimesinic acid and N-methyl pyrrolidone were measured and characterized by HPLC, TG and XRD. The results show that adduct is a kind of crystal with one trimesinic acid molecule and three N-methyl pyrrolidone molecules by O–H···O hydrogen-bonding. The crystal is unstable above 75 °C, which it is prone to decomposition in some certain solvents. The computational hydrogen-bonding energy between trimesinic acid and N-methyl pyrrolidone is -127.9 KJ mol-1, which can be categorized to the strong hydrogen bond.
