Introduction:

Dimethyl terephthalate(DMT) is an essential compound in organic synthesis, primarily used as a precursor for polymers like polyethylene terephthalate. Its selective hydrogenation produces valuable derivatives, such as 1,4-cyclohexane dicarboxylate, with enhanced efficiency achieved through non-precious nickel-based catalysts modified with potassium. While various in vitro studies classify dimethyl terephthalate as nongenotoxic, some in vivo studies indicate potential clastogenic effects, suggesting complex biological interactions that remain poorly understood. Further research is necessary to clarify these effects and to establish safety guidelines for the industrial application of dimethyl terephthalate, ensuring both efficiency in production and protection of human health.
