CHLOROACETONE PRODUCTION PROCESS Russian patent published in 2004 - IPC

FIELD: industrial organic synthesis. SUBSTANCE: safe chloroacetone production process resides in catalytic chlorination of acetone: first at 300-400 C in gas- vapor phase and acetoneto-chlorine molar ratio 1:(2-3) in a medium consisting of organohalogen compounds C1-C3 containing at least three halogen atoms in molecule (fluoro- , fluorochloro-, and chloro-derivatives of methane, ethane, and propane) at acetone concentration in its mixture with organohalogen compounds equal to 4.2 wt %, followed by second-step chlorination at 130-170 C. EFFECT: enabled high-output production of chloroacetone isomers. 2 ex
