Summary: The video documents a historical synthesis of chlorbutyl (chlorbutol) hemihydrate from acetone and chloroform under basic conditions using potassium hydroxide, including mixing, cooling, filtration, solvent removal, and a final crystallization from ice water to yield about 25% of the product with a minty aroma. Chlorbutyl is described as an antiseptic and sedative; chloroform acts as a reactive reagent under basic conditions. Cautions note acetone is highly flammable and requires ventilation.
