Efficient synthesis of styrene carbonate from CO2 and styrene oxide using zinc catalysts immobilized on soluble imidazolium-styrene copolymers was written by Qiao, Kun;Ono, Fumitaka;Bao, Quanxi;Tomida, Daisuke;Yokoyama, Chiaki. And the article was included in Journal of Molecular Catalysis A: Chemical in 2009.HPLC of Formula: 915358-85-9 This article mentions the following:
Preparation of zinc catalysts (Zn/PS-IL[X], X = Br–, Cl–, BF4 –, and PF6 –) supported on imidazolium-styrene copolymers, as well as their catalytic use for the solvent-free synthesis of styrene carbonate from CO2 and styrene oxide, are described. Among the catalysts examined, Zn/PS-IL[Br] was proved to be the most efficient. When used in a homogeneous system during the reaction process, Zn/PS-IL[Br] gave a 97.5% yield of product with a TOF value that can be up to about 3800 h-1. Due to its immiscibility with ethanol, Zn/PS-IL[Br] can be separated like a heterogeneous catalyst through solvent precipitation, and reused at least three times for the reaction without significant loss of activity. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9HPLC of Formula: 915358-85-9).
1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).HPLC of Formula: 915358-85-9
