| titleOfInvention | Phenylalanine-substituted calix [4] arene bonded silica gel stationary phase, preparation method thereof, and application thereof |
| abstract | The invention relates to a phenylalanine-substituted calix [4] arene bonded silica gel stationary phase, a preparation method thereof, and an application thereof. According to the invention, gamma-aminopropyltrimethoxysilane is adopted as a coupling agent; with a catalyst and under the protection of an inert gas, the coupling agent is subject to a reaction with specially prepared silica gel, such that gamma-aminopropyltrimethoxy bonded silica gel is prepared; with a catalyst and under the protection of an inert gas, the gamma-aminopropyltrimethoxy bonded silica gel is subject to a reaction with 25,27-di(L-methyl phenylalanine-N-carbonylmethoxy)-26,28-dihydroxy-p-tert-butyl calix [4] arene, such that the phenylalanine-substituted calix [4] arene bonded silica gel stationary phase is obtained. The bonded stationary phase provided by the invention has high bonding amount, stable performance, and better separation selectivity. The bonded stationary phase has a traditional ODS reversion phase chromatography performance, and can provide various action sites such as inclusion action sites and hydrogen bond action sites. The bonded stationary phase has a certain advantage in separating some specific substances that are hard to separate. |
