Question

According to today's experiment, how can you separate and recover p-toluidine, 2-naphthol, and p-dichlorobenzene? OH CI p-toluidine 2-naphthol p-dichlorobenzene

Extraction

This experiment is extraction

Answer 1

ronat The question is based on the extraction and so separation of p-toleridine, 2-Naphthol and p-dichlorobenzene. (the mixture) » All three were dissolved in ethanol to get a solution. 2) To this alcoholic solution, an aqueeres solution of Nach was added. TOTOOH Nach TOTO tho -naphthol (Sodium Balt) p 2-naphthol will form sodium salt and go into aqueous layer while remaining two will remain unreacted es alcoholic organic solvent. 3) Both layers were separated using separatory funnel. (Top layer organic ? Bottom" Aqueous, 4) To the aqueers layer collected, conc. He was added Le Toyonat Hal LOLOH Nach ware We get back 2-Naphthol is solid form.

5 To the organic layer, Mason was added to absoob moisture followed by addition of HCl solution NHL Hi Lect (salt) Ip-toluidine will form ammoniumsalt and go into aquears layer ren leaving behind p-dichlorobenzene in the organic layer. 6) Both Jayers were separated using 1. stop layer torganic T Bottomas Aqueens THE To the aqueous layer, Nach solution was added. TO THz a Nath NH2 thael We get back, b-totuidine which was searated thereaftar (Solid) (8) Organic layer was dried with Masoy (Anhydrous) followed by addition of ether. 19 The solent was evaporated teaving behind ß-dichlosebenzere Thus, the mixture was separated.
