WebNov 14, 2024 · In this work, we studied the effect of piperazine, a major by-product, acting as an additive, on the thermodynamics and nucleation kinetics of the triethylenediamine (TEDA)–methyl tertiary butyl ether (MTBE) crystallization process. It was found that the solubility of TEDA in MTBE increased with increasing amount of piperazine. WebThis showed that PdAg NPs immobilized on the triethylenediamine (TEDA) functionalized MIL-101-NH 2 catalyst with an average size of 1.6 nm, denoted PdAg/TEDA-MIL-101-NH 2, possessed the highest TON of 1500 at 70 °C after 10 h.
