METHOD FOR PREPARING CHLOROFORM Russian patent published in 2007 - IPC C07C19/04 C07C17/361 

FIELD: chemical technology.

SUBSTANCE: invention relates to a method for synthesis of chloroform. Method involves hydrolysis or hexachloroacetone with water at increased temperature in the presence of inorganic silicon compound of natural or synthetic origin or mixture of such compounds as a catalyst followed by isolation of chloroform from the reaction mixture by the known methods. Talc, wollastonite, xonotlite, diatomite, silica gel, aerosil, silica filler, silicates and/or hydrosilicates of metals, such as sodium, potassium, magnesium, calcium, aluminum, copper, titanium, lead, manganese, iron and nickel are used as silicon compounds indicated above. Catalyst is used preferably in the amount 1-25% of the reaction mixture mass. Invention provides the significant simplifying technology in synthesis of chloroform based on elimination the catalyst regeneration step and expanding the raw base of substances used in the catalytic process.

EFFECT: improved method of synthesis.
