  • 方法一:多用氰化酯化法。氯乙酸与碳酸钠中和生成氯乙酸钠,再用氰化钠进行氰化得氰乙酸钠。氰乙酸钠水解成丙二酸钠,然后在硫酸存在下与甲醇酯化得丙二酸二甲酯,经洗涤、蒸馏即得成品。工业品含酯量≥98%。原料消耗定额:氯乙酸1120kg/t、氰化钠551kg/t、甲醇955kg/t。国外开发的新工艺主要以催化羰基化法为主,即以氯乙酸酯、一氧化碳、甲醇为原料,在催化剂存在下,一步反应合成丙二酸二甲酯。相比之下,催化羰基化法工艺技术先进,但工艺复杂,反应条件苛刻,工业化实现有一定的困难。

  • 用途二:丙二酸二甲酯是生产医药吡哌酸的重要原料。国外丙二酸二甲酯主要用作非乙氧甲叉工艺生产吡哌酸的原料,与原甲酸酯和尿素反应生产吡哌酸。目前我国相关企业生产的丙二酸二甲酯除出口外,绝大部分用来生产吡哌酸。
