碳苷型半乳糖甘油单脂类似物的合成

以五乙酰基保护的D-半乳糖为初始物,经立体选择性烯丙基化、碱性高锰酸钾氧化、选择性酯化及水合肼脱保护,以简便有效的方法,合成了一类新型碳苷半乳糖甘油单脂天然产物类似物——1-O-酰基-2-羟基-3-α-D-吡喃半乳糖基丙脂。

Field Tests of the Catalyst ＂Mukhamedzhan-l＂ for the Detoxification of Propellant UDMH in the Position the Space Center ＂Baikonur＂ in Kazakhstan

The results of field tests of the catalyst ＂Mukhamedzhan-l＂ for the detoxification of propellant UDMH （unsymmetrical dimethylhydrazine） in the position the space center ＂Baikonur＂ in Kazakhstan were studied. Results of field tests have shown high efficiency of the catalyst ＂Mukhamedzhan- 1＂ for detoxification UDMH.
