[交流] 【求助】哪有卖分层双羟基化合物 (LDH)的啊?

各位大侠,兄弟姐妹们,哪里有卖分层双羟基化合物 (LDH)的啊?该怎样储存呢?

xfg12315(金币+3):非常感谢,我们实验室条件有限,但是氮气还是有的。我试一下吧。 2010-03-26 18:49

谢谢!我查过一些文献。制备碳酸根插层的比较容易,其他的如硝酸根插层的就对实验条件要求高一些。请问如何制备除碳酸根的纯水?简单的煮沸能满足实验要求吗?LDH能不能一次制备较大量,储存起来备用?储存应注 ...

First, here Max-Planck-Institut has no Chinese input, thus I only can use English. Second, it is easy to prepare NO3-LDH using double titration under nitrogen protection. For example: (1) Efficient synthesis of benzoin methyl ether catalyzed by hydrotalcite containing cobalt; Catalysis Communications, Volume 9, Issue 6, 31 March 2008, Pages 1128-1131. (2)Preparation, Characterization, and Catalytical Application of MgCoAl-Hydrotalcite-Like Compounds,Journal of Natural Gas Chemistry, Volume 16, Issue 4, December 2007, Pages 371-376 Kai Yan, Xianmei Xie, Jinping Li, Xiulan Wang, Zhizhong WangThird, LDH is easy to adsorb water. Before use, it is better to pretreatment under N2 or H2 for 2h. And then you can store a lot.

My Master Project is to synthsis and catalytic application of LDH. This material is easy to synthesize. Im my master study, my professor and I, we sucessfully prepare double elemnts HT containing Cu. We have some good publications. But now, I am in Germany. My project is changed into nano-catalyst via application in transformation of biomass. I think you see some literatures, you will get enough information.

分层的LDH是指单层的吗,LDH要是想用单层的话,最好自己制备,没听说哪有出售单层的LDH
工作中,合成管理、安全
