Dichlorid kyseliny fumarove - Production method
It is obtained by the reaction of maleic anhydride and phthaloyl chloride in the presence of zinc chloride. Heat maleic anhydride, industrial phthalic chloride and anhydrous zinc chloride at 130-135 ℃ for 2 hours, and pay attention to avoid overheating. Then it is cooled to 90-95 ℃, and distilled quickly. The 62-64(1.73kPa) fraction is collected as trans-butene diacyl chloride with a yield of about 90%. In addition, trans-butene diacyl chloride can also be prepared by reacting fumaric acid with phthalyl chloride or thionyl chloride or phosphorus pentachloride.
