Description
技术领域
本发明属于配位化学领域,具体涉及一种二硫代氨基甲酸铁配合物催化剂的制备方法与用途。
背景技术
配合物一般指由过渡金属的原子或离子与含有孤对电子的配体分子通过配位键结合形成的一类化合物。配合物广泛应用于日常生活、工业生产及生命科学中,近些年来的发展尤其迅速。在工业生产中,配合物可用于配位催化,例如,合成氨工业中用醋酸二氨合铜除去CO,有机金属催化剂催化烯烃的聚合反应或寡合催化反应。
N,N-二甲基二硫代氨基甲酸具有强的配位能力,能够与很多过渡金属形成结构稳定的配合物。N,N-二甲基二硫代氨基甲酸铁又名福美铁或二甲氨基磺酸铁。黑褐色粉末,稍有气味,在熔融前分解,主要用于叶面的保护性杀菌剂,对作物无药害。J.Alberttsson等人对二甲氨基磺酸铁的生物医学性能进行了研究报道(Acta Crystallogr.,Sect.B,1981,37,50;Acta Crystallogr.,Sect.B,1997,1871,33)。有关该配体铁配合物的作为催化剂目前研究报道较少。氯化铁(ferric chloride),化学式FeCl3,是一种共价化合物,为黑棕色结晶,也有薄片状,熔点306℃、沸点315℃,易溶于水并且有强烈的吸水性,能吸收空气里的水分而潮解,FeCl3从水溶液析出时带六个结晶水为FeCl3·6H2O,六水合氯化铁是橘黄色的晶体,氯化铁是一种很重要的铁盐。氯化铁主要用于金属蚀刻,蚀刻包括铜,不锈钢、铝等材料的蚀刻;污水处理,对低油度的原水处理,具有效果好、价格便宜等优点,但带来水色泛黄的缺点。氯化铁用于印染滚筒刻花、电子工业线路板及荧光数字筒生产等;建筑工业中用于制备混凝土,以增强混凝土的强度、抗腐蚀性和防水性;也能与氯化亚铁、氯化钙、氯化铝、硫酸铝、盐酸等配制成泥凝土的防水剂;在无机工业用中作制造其他铁盐和墨水;在染料工业中用作印地科素染料染色时的氧化剂;在印染工业中用作媒染剂;在冶金工业中用作提取金、银的氯化侵取剂;在玻璃工业中用作玻璃器皿热态着色剂;在制皂工业中用作肥皂废液回收甘油的凝聚剂;在有机工业中用作催化剂、氧化剂和氯化剂。氯化铁的另外一个重要用途就是五金蚀刻,蚀刻产品如:眼镜架,钟表,电子元件,标牌铭牌。氯化铁作为催化剂在中性溶液条件下,容易发生水解生成沉淀而失活,循环使用性能差。将三价铁离子与有关配体反应,制备相应的配体,有利于提高铁离子的稳定性,抑制其水解,有利于提高铁的催化剂的循环性能。随着社会的发展以及对环境保护要求的不断提高,人们对现有催化剂的循环使用、催化效率、廉价易得等提出了新的要求。
