查询词典 chelating

A preparation method of poly N-2-carboxyethyl pyrrole metal chelating nanometer pipe used as affinity absorbing medium relates to an affinity absorbing medium material.

用作亲和吸附介质的聚N-2-羧乙基吡咯金属螯合纳米管的制备方法，涉及一种亲和吸附的介质材料。

Phytates,the salt form of PA chelating with cations such as K~+, Ca~(2+),Mg~(2+),Zn~(2+) and so on,are mostly accumulated in the aleurone and embryo part of cereal seeds.

植酸是作物种子中含磷最丰富的化合物，占种子干重的1%以上，种子全磷含量的65%-85%和酸溶性肌醇磷酸盐的90%以上，易与K~+、Ca~(2+)、Mg~(2+)和Zn~(2+)等金属离子螯合形成植酸盐，主要沉积在作物的糊粉层和胚中。

We transformed RMgBr into R-Ti derivatives with the production of byproduct MgBrO~(i-Pr at the same time, but we didn\'t need romove the Mg salt by centrifugation or chelating reagents, for bis[2-(N,N-dimethylamino)ethyl] ether could chelate with Mg atom and thereby reduced the Louis acidity of Mg salt, so we used R-Ti derivatives produced in situ to alkylate the aldehydes induced by BINOL-Ti complexes..

我们通过利用TiO~(i-Pr_4使格氏试剂转化成烷基钛，同时产生具有亲核加成促进作用的副产物MgBrO~(i-Pr，由于BDMAEE能与MgBrO~(i--Pr络合降低其路易酸活性，所以不需要离心或者借助络合试剂完全除去镁盐，而使用原位生成的烷基钛在BINOL-Ti诱导下对醛进行不对称加成。

Objective To investigate the in vitro antimalarial effect of daphnetin relating to its iron-chelating activity.

The thesis investigated the effect of reation temperation, pH value, and material ratio on the chelating reation. To determine the L-aspartic acid zinc complex\' chelation ratio by orthogonal experiment, we get the best conditions of reaction. On this basis, the thesis synthesized L-aspartic acid autunite complex and L-aspartic acid coppe complex.
