synthesis
A simple process gadolinium acetate synthesis method, the specific steps are as follows:
1) 35~45ml of analytically pure glacial acetic acid and 0.0008 ~ 0.0012mol of gadolinium oxide are put into the reactor, stirred evenly and refluxed at 60~120 °c until the reaction solution is transparent;
2) Take 5.0 ~ 7.0ml of deionized water, add to the reaction solution, continue to stir at 60~120 °c until the solution is transparent;
3) after the reaction is complete, the heating is stopped, the reaction liquid is evaporated with a rotary evaporator until the liquid disappears, and the solid obtained by evaporation is dried in vacuum to obtain white powder gadolinium acetate, the distilled acetic acid solution was recovered and applied.
compared with the prior art, the beneficial effects of the present invention are that the distilled acetic acid can be recovered and applied; No other desiccant is needed for drying; The process flow is simple, the environment is not polluted, and the acetic acid consumption is small, the product yield and purity are high, the product phase is good, the economic added value of the product is improved, and a feasible method for industrial production is provided.
apply
acetic acid rolling can be used for alloy material additives, chemical reagents and other industries. Application examples are as follows:
A gadolinium-doped hollow vesicle structure nanocomposite, which is mainly composed of gadolinium-doped silica hollow vesicles, in the host surface modification photosensitizer and polyethylene glycol with silane, the host, the molar number of gadolinium and the mass ratio of silica is 0.8~1.5mmol:80~120mg, the host, the weight ratio of the photosensitizer to the silane-containing polyethylene glycol is 40-50:0.5-1.6:30-50. Etching of solid spheres into hollow spheres is a surface-catalyzed reaction. The composite material uses gadolinium acetate as etching agent, solid silica microspheres as Silicon source and hard template, and CO2 generated by acetate at high temperature as soft template to synthesize hollow vesicle microspheres in one step, re-modifying the photosensitizer imparts the material with photodynamic and photothermal properties for the preparation of contrast agents or functional materials with photodynamic and photothermal therapeutic effects.
