• Metal carboxylate salts

  A dietary source of mineral in the form of a metal carboxylate is prepared using the acid-base-like reaction. A salt of a carboxylate anion and a by-product cation is reacted in aqueous solution with a salt of a metal cation and a by-product anion under conditions which form a metal carboxylate and the by-product salt. Solutions formed in the reaction may be applied directly to a dry carrier to produce a dry dietary supplement or, alternatively, the solutions may be filtered to remove precipitated by-product salt and the filtrate used as a liquid dietary supplement. Preferably, a reducing agent, such as ascorbic acid, is added to help prevent the oxidation of divalent to trivalent form of a metal salt, when an easily oxidized divalent metal is used as starting material.

  使用酸碱类似反应制备以金属羧酸盐形式存在的矿物质的膳食来源。通过在水溶液中使羧酸盐阴离子和副产物阳离子的盐与金属阳离子的盐和副产物阴离子在条件下反应，形成金属羧酸盐和副产物盐。反应中形成的溶液可以直接应用于干载体上制备干燥膳食补充剂，或者可以将溶液过滤以去除沉淀的副产物盐，然后将滤液用作液体膳食补充剂。最好在使用易被氧化的二价金属作为起始材料时，添加还原剂，如抗坏血酸，以帮助防止金属盐从二价氧化为三价的氧化。

  Abstract The decomposition of freeze-dried mixed carboxylates of manganese and iron was investigated by means of DTA, TG, mass spectroscopy and X-ray powder diffractometry. The three main steps of decomposition are characterized as release of (a) H 2 O, (b) carboxylic acid and CO 2 /CO, and (c) the corresponding carbonyl compound and CO 2 . In particular, the course of process (b) strongly depends

  摘要 采用差热分析(DTA)、热重分析(TG)、质谱法和X射线粉末衍射法研究了冻干锰铁混合羧酸盐的分解过程。分解的三个主要步骤的特征在于释放 (a) H 2 O，(b) 羧酸和 CO 2 /CO，以及 (c) 相应的羰基化合物和 CO 2 。特别是，过程 (b) 的过程在很大程度上取决于三种研究的羧酸盐中金属-羧酸盐连接的稳定性。通过适当组成的甲酸盐的分解和分解产物在600°C下的热处理，同时保持ap (O 2 )在锰铁氧体的共存场内，可以获得结晶良好的单相铁酸锰。

  Hz indicates an S = 7 ground state for 1, 2, and 3. Magnetization hysteresis data were collected on a single crystal of 1 in the 0.27-0.9 K range and on single crystals of 2 and 3 in the 0.1-0.9 K temperature range. Discrete steps in the magnetization curves associated with resonant quantum tunneling of magnetization (QTM) confirm these complexes to be single-molecule magnets. The appearance of extra

  The syntheses, crystal structures, and magnetochemical characterization are reported for the new mixed-valent Mn clusters [(Mn2MnIII)-Mn-II(O2CMe)(2)(edteH(2))(2)](ClO4) (1), [(Mn2Mn2III)-Mn-II(edteH(2))(2)- (hmp)(2)cl(2)](Mn(II)cl(4)) (2), [(Mn6O2)-O-III(O2CBut)(6)(edteH)(2)(N-3)(2)] (3), [(Na2Mn8Mn2O4)-Mn-III-O-II(OMe)(2)(O2CEt)(6)(edte)(2)(N-3)(6)] (4), and (NEt4)(2)- [(Mn8Mn2O4)-Mn-III-O-II(OH)(2)-(O2CEt)(6)(edte)(2)(N-3)(6)](5), where edteH(4) is N,N,N',N'-tetrakis-(2-hydroxyethyl)ethylenediamine and hmpH is 2-(hydroxymethyl)pyridine. 1-5 resulted from a systematic exploration of the effect of different Mn sources, carboxylates, the presence of azide, and other conditions, on the Mn/edteH(4) reaction system. The core of 1 consists of a linear (MnMnMnII)-Mn-II-Mn-III unit, whereas that of 2 is a planar Mn-4 rhombus within a [(Mn2Mn2III)-Mn-II(mu(3)-OR)(2)] incomplete-dicubane unit. The core of 3 comprises a central [Mn-4(III)(OR)(2)] incomplete-dicubane on either side of which is edge-fused a triangular [Mn-3(III)(mu(3)-O)] unit. The cores of 4 and S are similar and consist of a central [(Mn2Mn2III)-Mn-II(mu(3)-OR)(2)] incomplete-dicubane on either side of which is edge-fused a distorted [(MnMn3III)-Mn-II(mu(3)-O)(2)(mu(3)-OR)(2)] cubane unit. Variable-temperature, solid-state direct current (dc) and alternating current (ac) magnetization studies were carried out on 1-5 in the 5.0-300 K range, and they established the complexes to have ground state spin values of S = 3 for 1, S = 9 for 2, and S = 4 for 3. The study of 3 provided an interesting caveat of potential pitfalls from particularly low-lying excited states. For 4 and 5, the ground state is in the S = 0-4 range, but its identification is precluded by a high density of low-lying excited states.

  The thermal decomposition in non-isothermal conditions of formates, acetates, propionates and butyrates of Mn, Co, Zn, Cd, Eu, Sm and Ni was studied. The observed compensation effect allows us to calculate the isokinetic temperature. A selective activation mechanism was suggested. This leads to a good agreement between kinetic and spectroscopic data.
