详细合成路线

溴代仲丁烷上游产品

溴代仲丁烷下游产品

由仲丁醇在硫酸存在下与溴氢酸反应而得。将浓硫慢慢加入氢溴酸中混合，再加入仲丁醇，回流反应2-3h，蒸馏出溴化物，将馏出液分层，取有机相依序用水、浓盐酸、水、碳酸钠稀溶液、水洗涤，用无水氯化钙干燥。最后蒸馏收集90.5-92.5℃馏分即得成品。

Validated methods for degrading hazardous chemicals: some halogenated compounds.

Am. Ind. Hyg. Assoc. J. 52(6) , 252-7, (1991)

Two techniques were investigated for degrading a number of halogenated compounds of commercial and research importance. Reductive dehalogenation with nickel-aluminum alloy in potassium hydroxide solut...

Enantioselective surface chemistry of R-2-bromobutane on Cu(643)R&S and Cu(531)R&S.

J. Phys. Chem. B 110(21) , 10411-20, (2006)

The enantioselective surface chemistry of chiral R-2-bromobutane was studied on the naturally chiral Cu(643)R&S and Cu(531)R&S surfaces by comparing relative product yields during temperature-programm...

Microbial growth on 2-bromobutane.

Antonie van Leeuwenhoek 46(4) , 331-41, (1980)

A member of the genus Arthrobacter was isolated which grew at the expense of 2-bromobutane as sole source of carbon and energy. Evidence is presented which suggests that the initial conversion of 2-br...
