苯并咪唑酮类高档有机颜料及其专用中间体 总被引:4,自引:0,他引:4
苯并咪唑酮类(Benyimidayolone)颜料是属于高档类有机颜料系列,它具有色光鲜艳,生产工艺简单,优异的应用性能,着色强度高等特点。由于颜料分子中含有环状酰氨基(-NHCONH-)的苯并咪唑酮通过与相邻分子间形成氢键,改变了分子聚集状态,使颜料具有更高的熔点,可明显降低在溶剂中的溶解度,使之具有优异的耐光、耐气候牢度、耐溶剂性、耐迁移性及耐热稳定性。本文重点介绍该系列颜料的品种、结构、性能、合成技术及其专用中间体的合成和应用。 相似文献

有机颜料的主要品种二十年来几乎没有什么变化,但是国外的一些厂家一直致力于新品种开发。象苯并咪唑酮颜料、喹吖啶酮颜料、大分子缩合颜料、四氯异吲哚啉酮颜料等都为大家所熟悉。本文介绍国外近年来已经商品化的一些有机颜料新结构及其合成路线,供国内颜料工作者参考。一、黄色偶氮颜料双偶氮缩合颜料虽然广泛用于塑料工业,但通常不能满足涂料用颜料的性能要求。1977年投放市场的C.I.颜料黄155,其价格比较便宜,可以用于涂料,为绿光黄色颜料。C.I.颜料黄155是帝国化学公司和山道士 相似文献

一、国外有机颜料发展的特征有机颜料工业是随着有机合成化学的发展而促进了新品种、新结构颜料的发展的。在十九世纪末已合成了对位红、立索尔大红;至二十世纪相继上市了还原蓝、金光红C、立索尔宝红、甲苯胺红、耐晒黄、联苯胺黄和橙。三十年代开发的2 B红、二噁嗪紫和酞菁颜料,显示了大分子量、金属络合、杂环结构的高耐久性颜料的优越性,成为有机颜料发展的里程碑。在五十年代中,偶氮缩合颜料、喹吖啶酮颜料、芘颜料相继进入市场,完善了高级颜料的色谱。六十年代,偶氮颜料、杂环颜料向改进耐热性,提高色泽鲜亮度、耐光度发展,出现了苯并咪唑酮颜料和缩合型对称多卤代异吲 相似文献

A series of novel poly(ether ether ketone)s containing benzimidazolone groups (PNBEEKs) with precise structures in high yields were synthesized from various stoichiometric ratio mixtures of benzimidazolone, 4,4′-dihydroxybenzophenone and 4,4′-difluorobnzophenone via a C–N/C–O coupling reaction process using sulfolane as a solvent. The reaction was carried out at 210 °C in the presence of anhydrous potassium carbonate. The structures of the resulted polymers were characterized by means of FT-IR, 1H NMR spectroscopy, 13C NMR spectroscopy, and elemental analysis, and the results were largely consistent with the proposed structure. XRD studies revealed that the incorporation of benzimidazolone groups increased the crystallinity of the resulted polymers. At the same time, as the benzimidazolone unit content in the copolymer increased, the solvent resistance properties and thermal properties of the prepared polymers improved. The polymers showed high glass transition temperatures (Tg?=?126–221 °C) and high thermal stability (Td5%?=?497–593 °C in nitrogen, 466–588 °C in air). Moreover, the resulted polymers showed good fluorescence properties and the fluorescence emission peak was 435 nm. 相似文献

During the investigation of dyeing properties of reactive dyes containing a benzimidazolone residue the negative influence of salt concentration on their exhaustion was demonstrated. In the case of model dyes not containing the reactive group, change in aggregation state at various temperatures was investigated. It has been shown that the reactive dyes containing a benzimidazolone residue may undergo excessive aggregation in concentrated sodium chloride solution. This may cause difficulties in the dyeing process. 相似文献

This work presents a method of preparing single-, double-, and triple-cation ferrite pigments by employing simple chemical
techniques to study their corrosion protection properties. The prepared pigments were characterized using X-ray diffraction
and scanning electron microscopy. All prepared ferrite pigments were evaluated using ASTM methods. Anticorrosive paint formulations
were performed using different prepared pigment loadings. The physico-mechanical and corrosion properties of dry paint films
were examined. The tests revealed that the prepared ferrite pigments show excellent anticorrosive behavior, and that the best
among them in performance are zinc and zinc magnesium. Calcium, zinc–calcium, and zinc–magnesium–calcium ferrites show better
performance in high pigment loadings, while magnesium ferrite pigments show good results only in low pigment loading. 相似文献

Nano-sized CoAl2O4 pigments, which have received significant attention as a coloring agent in glaze and bulk tile compositions, were successfully synthesized by substituting mechanical stirring during hydrothermal process with ultrasonic irradiation. Difference in physicochemical and optical properties of the CoAl2O4 pigments prepared by an ultrasonic-assisted-hydrothermal method was characterized using simultaneous thermo-gravimetric and differential thermal analysis (TG–DTA), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), diffuse reflectance spectroscopy, CIELAB colorimetric analysis, and testing in ceramic glazes and bodies. The ultrasonic-assisted CoAl2O4 pigments present a narrow particle size distribution with vivid blue color, and better thermal stability, allowing their use for ceramic inks processed at high temperature. Application of ultrasonic irradiation during the hydrothermal process produces nano-sized powders with better physicochemical and optical properties. 相似文献
