In this thesis, investigations focused on heteropoly acids-catalyzed C-C and C-N bond formation reactions and the synthesis of xanthenediones and acridinediones under thermal conditions are described.1.12-Phosphotungstic acid has been used as an efficient,eco-friendly,and air- and moisture-stable catalyst to promote the direct dehydrative substitution of the hydroxy group of benzylic and allylic alcohols with variousβ-dicarbonyl compounds.
本篇论文主要描述了杂多酸催化下的C-C和C-N键的生成,以及无溶剂直接加热下合成十氢氧杂蒽二酮和9-芳基十氢吖啶二酮。主要内容如下:1。在磷钨酸催化下,1,3-二羰基化合物与醇能够顺利偶合,脱除一分子的水,生成烷基化的1,3-二羰基化合物。反应在甲苯中进行时,二芳基甲醇能与各类1,3-二羰基化合物反应,成率很高;但对于1-苯乙醇,只能得到很低的产率。

In this paper, the marine soft soil is mixed with 10% cement added with 0.5% NaOH and 0.5% Na2CO3 separately, which form two types of new cement-soils. Comparing with the undisturbed soil and the 20% cement-soil results in that the alkalescence additive can contribute to generate a large number of needle-like, rod-like or fibriform hydrate calcium silicate crystals. The hydrate calcium silicate crystals can inhibit the generation of calcic alum crystal which would bring expansive action. At the mean time, it can separate out hydrate calcium. The hydrate calcium silicate crystals and hydrate calcium constitute the filling and inclusions together among soil particles and on the surface of soil particles, which cut down the interstices of cement soil obviously. Therefore, the soil mass can be reinforced and the intensity can be improved.
现场试验中将海积软土与分别掺入0.5%NaOH和0.5%Na2CO3的10%水泥就地搅拌,形成两种新型水泥土,在与原状土及20%纯水泥土进行比较后,发现碱性外掺剂可以促使生成大量针状、棒状或纤维状水化硅酸钙晶体,抑制了能产生膨胀作用的钙矾石的生成,同时,有Ca2晶体析出,它们共同构成土颗粒间和土颗粒表面的充填物和包裹物,使水泥固化土的孔隙明显减小,密度和强度得到极大提高。

In 0.015 mol/L NaOH medium, AuCl4(superscript -)reacted with hexadecyl trimethyl ammonium bromide, forming water soluble CTMAB-AuCl4 complex that exhibited a weak absorption peak at 400 nm. In the presence of hydrazine, the reaction produced orange-red nanogold particle and exhibited a surface plasma resonance absorption peak at 520 nm.

Aging mechanism of wood-plastic composite was: light and heat break down the long molecular chains of wood flour and plastic; the free radicals reacted with the oxygen, which generated carbonyl groups, hydroperoxides and so on; the free radicals also had cross linking reaction, which generated alkoxy; Water destroyed the interface of wood flour and plastic, hydrolyzed ester additives, extracted the small molecule additives and degradation products; Microorganism degraded cellulose, semicellulose, lignin and ester additives; degradation product from different component accelerated the aging, which could be exampled by the fact that HCl from degradation of PVC accelerated the hydrolyzation of cellulose and semicellulose.

As pH value varied in the course of diagenesis,reservoirs experienced one to three cementations or dissolution generations.Lots of secondary dissolution pores developed in the late diagenetic stage,because of the acidic mediums in the process of generation and migration of oil and gas. The anhydrites deposited in the dissolved pores resulted in the heterogeneity of secondary pores.
储层在成岩过程中受地层水pH值变化的影响,经历1~3个世代的胶结或溶蚀作用,其中在晚成岩期油气生成和运移过程中形成的酸性成岩环境对早成岩期生成的碳酸盐岩胶结物和储层中的长石矿物溶蚀,因而产生了大量的次生溶孔,但随后在溶孔中沉淀了不等量的硬石膏,导致了次生孔隙的非均质性。
