Chloroacetaldehyde - Preparation Method
Open Data Verified Data
chlorine and vinyl chloride were reacted in an oxidation column for 6 to 7 hours. When the content of chloroacetaldehyde reached 10%, the reaction was terminated, and then trichloroethane, a by-product, was separated to obtain an aqueous solution of chloroacetaldehyde.
