摘要:卤代硝基苯的胺化是生产相应硝基苯胺的重要反应.的直接胺化p-Chloronitrobenzene(p-Cnb)至p硝基苯胺(p-Nan)用含水nh 3溶液在不存在配体,无机碱和有机溶剂的研究了在各种过渡金属的盐.已经发现,就p-Cnb转化,P-Nan选择性(~100%)以及反应后分离和再循环而言,Cui是最有效的催化剂.高p的97%-Nan收率在200oc下在6.5小时,用nh的摩尔比来获得3 / P-Cnb和cui /p-Cnb分别为21和0.1.提出了一种可能的反应机理,其中nh 3不仅是底物,而且还是与cui配位的配体,形成了水溶性cu配合物,然后开始催化循环.研究了诸如nh 3浓度,Cui浓度,温度和时间等反应变量对p-Cnb转化率和p-Nan选择性的影响.在室温下,所需的p-Nan产物不溶于水,但cu络合物催化剂是水溶性的,因此包含催化剂和nh 3的水相可以轻松

摘要:A thermosensitive recording material comprising a thermosensitive layer provided on a substrate, and the thermosensitive layer comprises as main ingredients a leuco dye and a developer to make colored state of said leuco dye when heated, wherein the developer is an oligomer composition obtained from the reaction of a polyvalent isocyanate compound represented by following Formula (I) with an aromatic amine represented by following Formula (II); n nwhere X represents a try- or more-valent group, a represents an integer numeral of 3 or more, b and c represent respectively integer numerals in the range of 0 to 5 and they satisfy a relation of b+c=1 to 5, Z represents hydrogen atom, alkyl group, allyl group or aryl group, and the aryl group may include condensed ling structure thereof, and d represents an integer numeral in the range of 0 to 4. This developer shows excellent reliabilities of both image and background area, and also shows an excellent color-developing characteristics (color developing sensitivity and image density).
