生产方法及用途
生产方法
1.用苯酚起始原料经傅-克反应叔丁基化,再催化氢化生成相应的叔丁基环己醇,又经三氯化铬氧化转化为本产品。
2.制法: 于装有搅拌器、温度计、通气导管的反应瓶中,加入200mL甲苯,NCS8g(0.06mol),通入氮气,搅拌下冷至0℃。加入甲硫醚6mL(0.1mol),冷至-25℃,滴加4-叔丁基环己醇
(2)与40mL甲苯的溶液,约5min加完。加完后于-25℃搅拌反应2h。滴加三乙胺6g(0.06mol)与10mL甲苯的溶液,约3min加完。除去冷浴,5min后加入400ml乙醚,依次用1%的稀盐酸100mL、水100mL×2洗涤,无水硫酸钠干燥,减压浓缩。剩余物减压蒸馏,收集120℃/3.325kPa的馏分,得产品4-叔丁基环己酮①
(1)5.54~5.72g,收率90%~93%。注:①这是将伯醇、仲醇氧化为羰基化合物的一种方法,收率高。采用此方法可以合成如下各种羰基化合物(表I=7-5 286页)。
3.制法: 于装有搅拌器、通气导管的反应瓶中,加入540mg(3.46mmol)4-叔丁基环己醇
(2),50mL无水苯,0.2mL含有98mg(1mmol)无水磷酸①的无水二甲亚砜。通入氮气,搅拌下加入13.19g聚合物支载的碳二亚胺树脂(含有0.012mol活性炭二亚胺),室温搅拌反应3.5天。过滤,乙醚洗涤3次,每次100mL。合并有机层,水洗5次,每次100mL。浓缩至干,得产品
(1)446~450mg,收率83%~84%。mp42~45℃。注:①无水磷酸按照如下方法制备:5.58mL85%的磷酸中,加入五氧化二磷3.98g,加热15min使其全溶;或71g五氧化二磷冰浴冷却下滴加27mL水,使其全溶即可。
4.制法: 于装有搅拌器、温度计、滴液漏斗、通气导管的反应瓶中,加入CBS8.0g(0.06mol),甲苯200mL,通入氩气。搅拌下冷至0℃,加入二甲硫醚6mL(0.1mol),出现白色沉淀。以四氯化碳-干冰冷至-25℃,滴加4-叔丁基环己醇顺、反异构体的混合物
(2)6.24g(0.04mol)溶于40mL甲苯的溶液,约5min加完。继续于-25℃搅拌反应2h,滴加三乙胺6.0g(0.59mol)溶于10mL甲苯的溶液,约3min加完。撤去冷浴,5min后加入400mL乙醚。有机层用100mL(1%)的盐酸洗涤,而后用100mL水洗涤。无水硫酸镁干燥,减压蒸出溶剂。剩余物转入50mL圆底烧瓶中,减压蒸馏,收集120℃/3.325kPa的馏分,得化合物
(1)5.54~5.72g,收率90%~93%。放置后固化,mp41~45℃。
用途
适合于作为日化香精之用。
