First, you can apply the reflux condensation when the solvent has boiling point lower (example 50-60C) to avoid any loss amount and at same time the temperature of refluxing depends on the dissolve of starting materiel that can produce the final nano-particle. The reflux condensation as condition of method depend on the method and materiel's that using. I think the reflux condensation can be uses in sol gel or chemical precipitation or any methods. But the difference only on the principle of method.

Dear Muneer

Thanks for your explanation. the reflux condenser system can be used used for only avoiding or losing the solvent present in the reaction mixture, Reflux condensation is not a methods of anyone like sol-gel, chemical, co-precipitation and some other chemical methods. Just we are applying reflux condenser apparatus for producing nanoparticles not a specific method. I have seen one article, they put reflux condensation method in the title. suppose if I am using double condenser system for producing nanoparticles can i fix the name of the method like synthesis of __________ nanoparticles by reflux double condensation method. is this correct?

please clear about my doubt.
