Filtride

Near-synonyms: filtrand, residue (usually synonymous)

The filtride, i.e. the solid portions that are obtained from the filtration, adheres to the outer surface of the wire 2 and may be gathered, e.g. by means of a water jet, a doctor blade or the like.

After the monomer is consumed, the reaction mixture is cooled to room temperature. Then, filtration is employed to separate the solid filtride from the liquid filtrate.

The precipitate was filtered out, and the filtride on the filter paper was washed repeatedly with distilled water until the filtrate became neutral. Soxhlet extraction using ethanol and diethyl ether mixture was performed to remove unreacted reagents.
