De-ashing of naphthalene-based mesophase pitch synthesized by the AlCl₃-catalyzed method

摘要

摘要: 以催化剂三氯化铝（AlCl₃）和精萘在160～240℃下制备的萘沥青为研究对象，采用超声、搅拌、加热和酸碱洗涤的方法对萘沥青的脱灰进行研究。结果表明萘沥青在超声和搅拌的共同作用下，温度条件为80～90℃，先碱洗后酸洗时，脱灰效果最佳，可将萘沥青的灰分降低至500 ppm以下。用所得的萘沥青可以制备灰分低、性能优良的中间相沥青。

Abstract: Naphthalene asphalt was synthesized at 160-240℃ using naphthalene as a raw material and AlCl₃ as a catalyst, and its de-ashing by ultrasonic treatment, stirring, heating, and acid and/or alkali washing was investigated. Results indicated that naphthalene-based mesophase asphalt with an ash content less than 500 ppm could be prepared by twice washing in an alkali followed by acid washing for 4 times and finally water washing for 10 times at 80-90℃ under ultrasonic or stirring conditions.
