性质描述: 无色液体。沸点138℃(140℃),相对密度0.903(20/4℃),折光率1.4378,闪点42℃,溶于水、乙醚、乙醇,与水、甲醇等任意比互溶,在水溶液中呈弱碱性。
生产方法: 由六水哌嗪经甲基化反应而得。将六水哌嗪及盐酸加入反应锅中,加热至45℃,滴加甲酸和甲醛的混合液。加毕,在50℃左右反应2-3h,再升温回流,至二氧化碳气体不再逸出为止。冷却至80℃,加入盐酸,加热蒸酸至干。稍冷后加入甲醇,加热回流30min,趁热过滤(滤渣为哌嗪二盐酸盐)。滤液回收甲醇至尽,残液加入氢氧化钠溶液至pH=14,蒸馏,得含水甲基哌嗪。加苯加热回流带水至尽,分馏,收集132-140℃馏分,得无水甲基哌嗪。收率约50%。
用途: 有机合成中间体。在医药工业中用于制取抗菌素类药物甲哌利福霉素、抗精神病药三氟拉嗪等。主要用作氧氟沙星、氯氮平、西地那非、吐立抗、佐匹克隆等药物的中间体,亦可用于农药、染料、塑料等行业。

应用
1-Methylpiperazine is used in the preparation of 2-(4-methyl-1-piperazinylmethyl)acrylophenone. It is involved in the preparation of 1-(4-methoxy-phenyl)-4-methyl-piperazine by reacting with 1-chloro-4-methoxy-benzene. It acts as an intermediate in the synthesis of active pharmaceutical ingredients like ofloxacin, rifampicin, clozapine, sildenafil, trifluoperazine and zopiclone. Further, it is used as a mimic template in the preparation of molecularly imprinted microspheres. In addition to this, it is used in the generation of difunctional strong anion-exchange stationary phase from a 1,4-diazacyclohexane derivative.

备注
Hygroscopic. Moisture sensitive. Incompatible with acids, acid chlorides, acid anhydrides, strong oxidizing agents and carbon dioxide.
