Green plasticizers derived from epoxidized soybean oil for poly (vinyl chloride): Continuous synthesis and evaluation in PVC films
Green plasticizers Micro-flow system Continuous synthesis Mechanical performance
2024/1/12
In this paper, the epoxidation process and the ring-opening reaction were integrated to develop an efficient bio-based plasticizer in a continuous flow mode. Four novel plasticizers based on epoxidize...
Development and evaluation of a hydrogenated rosin (β-acryloxyl ethyl) ester–bonded silica stationary phase for high-performance liquid chromatography separation of paclitaxel from yew bark
Rosin-based stationary phase Paclitaxel Retention mechanism Separation Yew-bark extract
2023/12/5
Paclitaxel (PTX) is a complex diterpenoid anticancer drug whose separation from yew biomass poses a significant challenge. In this study, a new stationary phase comprising hydrogenated rosin (β-acrylo...
