Chromium-based Catalyst Method
Among many preparation processes, the synthesis of Hydroxypropyl Acrylate HPA using chromium-based catalysts is a traditional process route. Chromium-based catalysts mainly include chromium trichloride, chromium trioxide, and chromium acetate. They have relatively high catalytic activity but are difficult to prepare and the process is hazardous. Chromium-based catalysts are often used in combination with catalytic additives and polymerization inhibitors during use. In particular, chromium trioxide is a strong oxidant with extremely strong oxidizing properties and corrosiveness, making its storage and transportation very dangerous. A US patent reported the synthesis of Hydroxypropyl Acrylate HPA using organic chromium as a catalyst, with a reaction temperature of 80°C, a catalyst dosage of 2%, and a yield of 86.9%. The patent investigated the stability of the catalyst using a cyclic method to ensure its activity. Reported an experimental study on the synthesis of Hydroxypropyl Acrylate HPA using chromium acetate as a catalyst, with a reaction temperature of 85°C and a yield of 89.4%. However, since chromium is a heavy metal, it has teratogenic and carcinogenic effects. Moreover, after product purification, it mainly exists in the residual liquid, which has a high viscosity and makes the recovery and treatment of chromium acetate difficult. The development of green, safe, and environmentally friendly catalysts and processes has become a research hotspot in academia.
