This study was undertaken to determine whether acetylation of fiber could bring about marked improvement in properties of the hardboard. The pulp was acetyla; ted with 25 per cent (in volume) solution of acetic anhydride in xylene at 125C. The results obtained are as follows: (i) The acetylation of fiber resulted in a obvious expansion in the thickness of the hardboard and the increased dimensional stability is mainly due to the bulking effect. (2) After conditioning.the moisture content of the acetylated hardboard increased slightly. The conversion of cellulosic hybroxyl groups to less hydrophilic acetate groups reduces the amount of water absorbed by the fibers. (3) Swelling in thickness of the specimens in liquid water was cousiderably reduced. The acetylation imparts greater stability to the dimensions of the hardboard. (4) The acetylation does not significantly affect the dry bending strength of the hardboard.

本文研讨乙酰化可否显著提高硬质纤维板的性能。试验时所用纤维浆料为25%(体积比)醋酐的二甲苯溶液,在125℃下进行乙酰化。结果如下:(1)纤维乙酰化导致硬质纤维板厚度显著增加。尺寸稳定性的增加主要是由于增积的结果。(2)乙酰化纤维板在调湿后,含水率增加很小。纤维素羟基变换成憎水性乙酰基减少了纤维吸水量。(3)浸水厚度膨胀显著减小。乙酰化使硬质纤维板具较大的尺寸稳定性。(4)乙酰化对干弯曲强度无显著影响。

The coordination chemistry of ethylenediamine tetraacelic acid, EDTA, has been expensively investigated. It is highly effective for many cations over a definite pH range.

The coordination chemistry of ethylenediamine tetraacelic acid, EDTA, has been expensively investigated. It is highly effective for many cations over a definite pH range. The problem of selectivity and the complex formation in strongly acidic and strongly alkaline media remained unresolved. Considerable interest has been demonstrated in the synthesis and complexing properties of organophosphorus analogues of aminocaiboxylic acids in which the carboxyls have been partly 01 completely replaced by organophosphorus acid groupings. It has been shown that the replacement of acetate groups by methylenephosphonate groups significantly alters the specificity of the chelating agent.

The title compound is synthesized and crystallized in the monoclinic system; space group P1, a=10.761(2), b=13.930(4), c=15.117(2); a=114.74(2)°, β=101.82(2)°, γ=95.85(2)°; Z=1. The final R factor is 0.076 based on 2083 reflections with I≥3σ(I). In the title compound, coppcr(Ⅱ) ions are bridged in pairs by four acetate groups with two DMF molecules occupying the terminal positions. The copper(Ⅱ) ions are 0.20 out of the plane of the four oxygen atoms. The distance between the two copper(Ⅱ) ions is 2.635 which is only slightly greater than 2.55, the interatomic distance in metal copper. A weak bonding existed between the two atoms.SCC-EHMO calculation indicated that the frontier orbitals 38Ag, 37Bu, 21A_u and 20B_g are very close in energy. The remaining two electrons must be placed respectively in the two frontier orbitals 38A_g and 37B_u, resulting in paramagnetism. This can be illustrated by the ESR spectrum. The bonding and antibonding molecular orbitals of Cu-Cu σ,Ⅱ and δ are completely filled. There is no net bonding from those filled electrons. The weak bonding between the two copper(Ⅱ) ions is contributed by the 34B_u and 18A_u molecular orbitals that the electrons delocalized over copper and carboxyl atoms.

本文报导了的晶体结构。晶体属三斜晶系,空间群P_1,晶胞参数:a=10.761(2),b=13.930(4),c=15.117(4);a=114.74(2)°,β=101.82(2)°,γ=95.85(2)°;Z=1。标题化合物为四羧基桥的双核铜(Ⅱ)簇合物,DMF占据端基位置。Cu-Cu距离2.635(2),有微弱成键作用。SCC-EHMO计算表明前线轨道38A_g,37B_u,21A_u和20B_g能级相当接近,化合物为顺磁性,μ(eff)=1.82B.M.,根据顺磁谱出现的由三组峰组成的一套谱,其中在低场的一组峰分裂7条超精细结构峰,判断化合物顺磁性应是占据38A_g,和37B_u分子轨道上未配对电子的贡献。Cu-Cu的成键和反键的σ,π和δ型轨道都填满电子,因此对成键不起作用。Cu-Cu之间的微弱成键作用,主要是通过铜与羧基桥原子形成的非定域键的34B_u和18A_u分子轨道的贡献。
