磁性纳米颗粒(CoFe 2 O 4)负载的磷钼酸盐是一种高效,绿色,可回收的合成β-羟基氢过氧化物的催化剂
摘要:
AbstractMagnetic nanoparticles (CoFe2O4)‐supported phosphomolybdate ([CoFe2O4@SiO2‐PrNH2‐PMo]) was readily prepared and identified as an efficient catalyst for ring‐opening of various epoxides with ethereal hydrogen peroxide (H2O2). The reaction proceeded under mild conditions to give β‐hydroxy hydroperoxides (HHPs) in high yields at room temperature, and the catalyst could be magnetically separated and recycled.magnified image

The present invention provides a process for producing a polyester from a polyester composition comprising at least about 1 wt.% wollastonite, based on the total weight of the polyester composition, wherein the wollastonite is added at a temperature of about 240°C or less. The present invention further provides a process for producing a polyester from a polyester composition comprising at least about 1 wt.% wollastonite, based on the total weight of the polyester composition, and about 0.01 wt.% other filler, based on total weight of the polyester composition, wherein the wollastonite is added at a temperature of about 240°C or less. The invention is further directed to polyester products produced by said process and the shaped articles formed therefrom.
