octylferrocene is a ferrocene derivative. The non-benzene aromatic ring organometallic structure of ferrocene and its derivatives gives them unique properties, making them suitable for applications such as fuel oil fuel-saving and smoke-reducing agents, gas combustion-enhancing catalysts, ultraviolet absorbers, photosensitive catalysts, various pharmaceuticals, and bio-enzyme electrodes.
A method for efficiently preparing high purity n-octylferrocene by mixed solvent recrystallization, characterized in the steps as follows:
Step 1: Configure a solution of crude n-octylferrocene, polar protonic solvent containing hydroxyl group, polar nonprotonic solvent and nonpolar solvent in the ratio of 1U45U45U810 by volume;
Step 2: after precipitating n-octylferrocene crystals from the configured solution at a temperature of -10 to -80 , pour out 50% of the solvent, and then filter to obtain n-octylferrocene crystals; .
Replace the octyl ferrocene crude product of step 1 with the present octyl ferrocene crystals, and repeat step 1 to step 2 for six times;
Step 3: put the crystals collected after repeating six times in a vacuum oven at a temperature of 4060 and a relative vacuum of -0.05-0.08Mpa, keep it for 34h, then charge nitrogen until the inner and outer pressures are equal, then evacuate to -0.05-0.08Mpa, then charge nitrogen again, and repeat the process of charging nitrogen to evacuating for 810 times to get high purity n-octylferrocene The high purity n-octyl ferrocene is obtained.
