摘要： PURPOSE: A method for preparing oxirane compound is provided to enhance catalyst performance by removing diene compound and to maintain catalyst performance. CONSTITUTION: A method for preparing oxirane compound comprises: a step of contacting chlorine and aryl chloride for chlorination of diene compound; and a step of recycling unreacted aryl chloride, solvent, and extraction solvent. The diene compound is 1,5-hexadiene. A method for preparing oxyrane compound comprises: a step of contacting aryl chloride and chorine for chlorination and purification of diene compound; a step of reacting purified aryl chloride under the presence of hydrogen peroxide and catalyst to prepare epichlorohydrin; a step of extracting; a step of isolating epichlorohydrin and recycling solvent, extraction solvent and unreacted aryl chloride; and a step of inputting chlorine to a storage or supply tube.

摘要： PURPOSE: A method for preparing oxyrane compound is provided to remove diene compound existing in aryl chloride and to suppress reaction by-product. CONSTITUTION: An oxirane compound is prepared by chlorination of diene compound by contacting chlorine and aryl chloride. The diene compound is 1,5-hexadiene. A method for preparing oxyrane compound comprises: a step of contacting aryl chloride and chlorine for chlorination and purification of diene compound; a step of reacting the purified aryl chloride under the presence of hydrogen peroxide and catalyst to prepare epichlorohydrin; a step of extracting; a step of isolating epichlorohydrin by isolating and purifying; and a step of recycling unreacted aryl chloride.
