製備 編輯

1,10-癸二醇可以由癸二酸二甲酯德語Sebacinsäuredimethylester乙醇里和三氯化鈰催化下被硼氫化鈉還原而成。這個反應的時間為一天,產率 93%。[4]四丁基硼氫化銨還原二硫代癸二酸二乙酯的產物也是1,10-癸二醇。[5]癸二酸二乙酯液氨中的電化學還原也可以製備1,10-癸二醇,產率 95%。[6]

癸二酸和硼氫化二異丙基鈦(III)((iPrO)2TiBH4,由二氯二異丙基鈦和苄基三乙基硼氫化銨在二氯甲烷原位反應產生)的反應也能合成1,10-癸二醇。[7]

性質 編輯

1,10-癸二醇是難溶於水的白色固體。[1][3]它的熔點是81.7 °C,熔化熱 44.0 kJ·mol−1(252.6 J·g−1)。[2]這個分子有鋸齒狀結構。[8]

反應 編輯

1,10-癸二醇的溴化會生成1,10-二溴癸烷[9]而和氯化亞碸的反應則產生1,10-二氯癸烷[10]

1,10-癸二醇、氨水反應會生成癸二腈,產率高達 99%。[11]

用處 編輯

1,10-癸二醇和其異構體1,9-癸二醇1,2-癸二醇一樣都是土壤硝化作用的抑制劑,可以減少土壤的流失,也避免了農田硝化作用造成的環境問題。這些二醇也會高度抑制亞硝化英語Nitrosation微生物,即使在低劑量時也是如此。[12]
