CAS: 78-26-2
分子式: C7H16O2
分子量: 132.20
沸点: 230℃(753
熔点: 56-59℃
中文名称: 
2-甲基-2-丙基-1,3-丙二醇
英文名称: 
2,2-Bis(hydroxymethyl)pentane
2,2-Dimethylolpentane
3-Propanediol, 2-methyl-2-propyl-1
2-methyl-2-propyl-3-propanediol
2-methyl-2-propyl-1,3-propanediol
1,3-Propanediol,2-methyl-2-propyl-
性质描述: 白色结晶。熔点62-63℃(58-60℃),沸点230℃(100.4kPa),易溶于水。
生产方法: 由2-甲基-2-戊烯醛经催化氢化得到2-甲基戊醛,然后与甲醛进行羟甲基化、还原反应而制得该品。2-甲基-2-戊烯醛加氢反应100℃、1.3-1.5MPa下进行,收率80%。得到2-甲基戊醛后,将其加入36%的甲醛中,于室温下滴加氢氧化钠溶液。反应放热,自然升温至70℃,再加热至90℃,加流1h,冷却至60℃静置分层,上层液用水洗涤,洗液与下层液合并,用苯提取。将提取液和上层液合并,蒸馏回收苯后,进行减压蒸馏,收集160℃(14.7kPa)馏分,即为2-甲基-2-丙基-1,3-丙二醇,收率93%。
用途: 用于有机合成。弱安定药氨甲丙二酯的中间体。
