Description: In this video we'll be making methylamine hydrochloride by reacting ammonium chloride and formaldehyde solution....If you liked this video,

Subject: synthesis of methylamine hydrochloride from ammonium chloride and formaldehyde solution.
Overview: a multi-step laboratory procedure involving mixing, heating, distillation under vacuum, and crystallization to produce methylamine hydrochloride.
Procedure highlights: prepare reaction setup with a flask, stirrer, and thermometer; combine ammonium chloride with formaldehyde solution and stir; perform staged distillations with temperature monitoring; monitor gas evolution (carbon dioxide) as the reaction proceeds; allow crystallization to form; separate crystals from filtrate; recover and dry solids.
Purification: dissolve crude product in hot ethanol to exploit differential solubility (methylamine hydrochloride vs ammonium chloride); filter and wash crystals with warm ethanol; evaporate and crystallize; further purify using chloroform washes to remove dimethylamine; filter and dry the purified product; return any remainder to storage.
Final processing: chill filtrates to precipitate additional material; dry crystals and store under airtight conditions; some ammonium chloride may be recovered and reused.
Outcome: two batches of product obtained; assessment that an additional boiling-down step offered limited benefit given the yield from the initial crystallization.
