I want to collect my final product from chemical reaction , how to precipitate the product ? is there another method to collect the product.?
I'm not a chemist, so probably in no position to answer your question anyway, but I'm pretty sure more info is needed to answer it properly...what may precipitate/concentrate one compound will dissolve another...
best,
Christoph
Depends upon nature of product whether it is acidic ,basic ,phenolic, or neutral,or any,,,then after it will be quite easy
It is fortuitous when a product precipitates from a reaction mixture and can be collected by filtration. More often the solvent has to be removed before the product can be isolated. If the product is obtained as a solid then it can be collected by filtration and washed with a solvent that will remove the impurities without dissolving the product. Sometimes the residue requires trituration before a solid is obtained. Purification is another matter. If the solid is easily recrystalized then this should be done. If a significant amount of byproducts are to be removed , as indicated by TLC, then a chromatographic method should be used. Even after a chromatographic purification a solid should be recrystalized. If you are generating a series of compounds for biological evaluation the MP should be sharp, the H-NMR should show no solvents or other impurities, the HPLC should show only one peak, and the compound should be analytically pure.
You may want to consider salting-out assisted liquid–liquid extraction (*) ― for instance, while considering butyric acid and/or its conjugate base, you may check the signalled discussion (**). Adding a miscible non-solvent may also help to precipitate a solute from its mother solution.

if it is a organic reaction try to add various non-polar solvent to precipitate the compound.
