【発明の名称】1,2-ジクロロエタンの熱分解による塩化ビニルの製造方法
Document Type and Number:
Japanese Patent JP2593905
Kind Code:
B2
Abstract:
Gaseous 1,2-dichloroethane which has been produced in a variety of ways is heated indirectly by the hot, vinyl chloride-containing gases which are led away from the radiation zone of the pyrolysis furnace. This allows the heat of the pyrolysis gases to be utilised in a favourable manner, pyrolysis rates to be increased, and operation times of the pyrolysis furnace to be prolonged.
