甲基异丁基甲醇(MIBC)制备
先由丙酮在碱性催化剂存在下，加压缩合转化成二丙酮醇（见11360）。使用的催化剂为氢氧化钙或氢氧化钡。当催化剂粒子很小、表面积很大时，这一液相接触反应接近于均相反应。反应过程放出热量，低温下平衡转化率大。因此，原料丙酮要预冷，反应在0-10℃下操作。然后，二丙酮醇脱水生成异丙叉丙酮。过程获得的二两样酮醇，一般含量为10-15%，采用常压蒸馏浓缩至80%，同时分离和回收未转化的丙酮。在硝酸、硼酸或苯磺酸等酸性催化剂存在下，加热至100-200℃，二丙酮醇脱水生成异丙叉丙酮，转化率为80-85%。但二丙酮醇能受热分解成丙酮，因此脱水产物需回收基中的丙酮。最后上步反应是异丙叉两样酮加氢生成4-甲基-2-戊醇。实际上，如果以镍或铜为催化剂，气相加氢在常压下进行的条件比较温和时，则得到较多的部分加氢产物甲基异丁基甲酮。当温度控制为170-210℃，氢与异丙叉丙酮的摩尔配比加大时，则较多获得完全加氢产物甲基异丁基甲醇。而一般情况下得到的是两者混合物，精馏分离时采用减压蒸馏系统。也可以甲基-异丁基（甲）酮经镍催化加氢制成，经精馏塔分馏，得成品。
