其制备方法是在反应釜中投入水合肼、乙二醇，并在搅拌下投入4-甲基2-氨基苯并噻唑盐酸盐(如是4-甲基-2-氨基苯并噻唑还需投入适量的盐酸)。投料完毕，升温至116℃进行预蒸。同时通入氮气，前馏分收集后，经处理后弃去，收集116～122℃馏分为低沸物，低沸物经浓缩后套用，然后在122～124℃保温回流反应5h，保持通氮气状态，反应结束，停止通氮气，冷却至30℃，放入抽滤缸在真空条件下脱去母液，滤饼投入打浆釜，在35℃下加水进行打浆2h后放入抽滤缸抽去打浆水，然后滤饼再用水洗涤到终点，离心脱去洗涤水即为成品。反应过程中的母液打浆水浓缩液经浓缩后用气相色谱分析其中水合肼、乙二醇含量，然后可套入下一次反应。
