I have read quite a bit of literature and I found that while synthesizing Fe3O4 nanoparticles, people have chosen different solvents mainly based on their boiling point to favor nucleation or growth. But, how the solvent is chosen in accordance to the iron precursor (iron oleate, Iron acetylacetonate, iron pentacarbonyl etc.) What is the relation between those two because I have seen people use phenyl ether, benzyl ether, hexadecene, erucic acid etc. but WHY?
Some references regarding this issue will be very helpful.
in the first step choose the chemical formula of individual molecule and write the chemical reaction calculate molar wt. by molecular wt. for this many online fee tools available...
The solvent (dispersant) is selected for the following reasons:
1. small value, availability (water)
2.Water or oil magnetic fluid.
3. Critical mixture in the preparation of nanoparticles by the method of supercritical extraction.
4. less toxic
5. Isolation, nucleation of metal nanoparticles during thermal decomposition of a liquid organometallic compound.
6. A suitable liquid dispersant for laser ablation.
It is possible to give still the same reasons for the choice of dispersants.
Look for literature for your review.
Dear all, basically the solvent is chosen in accordance to the solubility parameter of both, solvent and solute, ideally good solvation is achieved for closer values of the solubility parameters. After that came the other aspects such as economy, toxicity, volatility and so forth. Normally all values of known substances are tabulated in handbooks. Regards
