多金属氧酸盐,这是一类主要由过渡金属和氧组成的化合物,具有同核和异核两个类别,英文一般简称为POMs,中文名为杂多酸。杂多酸研究发展至今,具有三个显著的历史阶段

摘要本论文的主要研究目标为一种多金属氧酸盐,这是一类主要由过渡金属和氧组成的化合物,具有同核和异核两个类别,英文一般简称为POMs,中文名为杂多酸。杂多酸研究发展至今,具有三个显著的历史阶段,从第一次发现多酸,到Miolati-Rosenheim学说提出后的深入研究,再到如今当代的研究发展状况,都标志着杂多酸越来越引起世界各地广大化学前沿研究者的关注。而之所以多酸能越来越引起广大化学研究员的关注,主要原因则在于它的广泛应用方面,特别显著的效果就是它在催化剂以及药物研究方面。在催化剂方面,它表现出有别于传统催化剂的良好优势,它具有四大显著特性:高调控性、高活性、高稳定性和高的热稳定性,并且这一类催化剂具有反应条件温和,没有毒性,没有腐蚀性以及可用于均质和异构系统的强大优势。另一个方面,在药物研究上,对于药物的分离、鉴定、化学毒物的毒理学研究和生物材料的分析这五个方面,杂多酸表现出了显著的优势和重要影响,随着当代多酸研究的不断深入,世界各地的化学研究员们又陆续在多肽链、蛋白质、酶催化的生物研究中加入Anderson结构多金属氧酸盐化合物,并发现它具有抗凝血、抗风湿的作用,而这些也即是多金属氧酸盐越来越引起大家的广泛关注的原因。目前,随着历史的进展,研究的深入,我们将杂多酸命名了六种经典的结构,分别为:Keggin结构,Dawson结构,Anderson结构,Waugh结构,Silverton结构,Lindqvist结构。而本论文的主要研究设计类型为Anderson结构的一种多金属氧酸盐。我们的合成方法是以Anderson型杂多酸为切入点,在多酸上引入功能化的有机基团。先利用六水合氯化铝和二水合钼酸钠合成母体,再利用季戊四醇对母体进行单侧修饰,再等其自然冷却静置结晶,从而合成我们所需要的产物Al-Anderson结构多酸催化剂。82099

Abstract The main research goal of this paper is a polyoxometallate, which is a kind of compound composed mainly of transition metal and oxygen。 It has two kinds of nuclei and heteronuclei。 English is abbreviated as POMs。 acid。 Heteropoly acid research has been developed so far, with three significant historical stages, from the first discovery of polyacids, to the Miolati-Rosenheim theory put forward after the in-depth study, and now to contemporary research and development status, are marked the more heteropoly acid To attract the attention of the majority of chemical researchers around the world。 And the reason why more acid can attract more and more attention of the majority of chemical researchers, the main reason is that it is widely used, the particularly significant effect is that it is in the catalyst and drug research。 In the catalyst, it shows a good advantage different from the traditional catalyst, it has four significant characteristics: high regulation, high activity, high stability and high thermal stability, and this type of catalyst with mild reaction conditions, No toxicity, no corrosiveness, and a strong advantage that can be used for homogeneous and heterogeneous systems。 On the other hand, in drug research, heterozygous acid showed significant advantages and important effects on the separation, identification, toxicological toxicological studies of chemical poisons and the analysis of biomaterials in five aspects。 In the deepening of research, chemical researchers from all over the world have successively added the Anderson structure of polyoxometallate compounds in peptide chains, proteins and enzyme-catalyzed biological studies and found that it has anticoagulant, anti-rheumatic effects That is, polyoxometalates are increasingly attracted to the cause of widespread concern。 At present, with the progress of history and research, we have named six kinds of classical structures: Keggin structure, Dawson structure, Anderson structure, Waugh structure, Silverton structure, Lindqvist structure。 The main research type of this paper is a polyoxometallate of Anderson structure。 Our synthesis method is based on Anderson type of heteropoly acid as the starting point, in the multi-acid on the introduction of functional organic groups。 First, the use of aluminum hexahydrate and sodium dihydrate hydrate synthesis of the mother, and then the use of pentaerythritol on the maternal unilateral modification, and then wait for its natural cooling and standing crystallization, which we need to synthesize the product Al-Anderson structure of multi-acid catalyst。 单边季戊四醇修饰的Al-Anderson型多金属氧酸盐的制备:http://www.youerw.com/huaxue/lunwen_96220.html
