标题:一种喹吖啶酮及其衍生物的制备方法
摘要:本发明涉及有机颜料合成领域,公开了一种喹吖啶酮及其衍生物的制备方法,步骤为:丁二酸二甲酯在甲醇钠的作用下自身缩合成环反应生成丁二酰丁二酸二甲酯钠盐,再酸化成丁二酰丁二酸二甲酯;丁二酰丁二酸二甲酯再与苯胺或者取代苯胺发生缩合反应,此缩合反应生成的中间产物直接与间硝基苯磺酸钠氧化去氢得到氧化产物;最后氧化产物在多聚磷酸的作用下闭环制得喹吖啶酮或者其衍生物的粗产品,最后经颜料化处理得喹吖啶酮或者其衍生物成品.

标 题 :Manufacturing and conditioning of solid solution organic pigments
发明人：BUGNON PHILIPPE; MAURER MARC
权利人:CIBA SC HOLDING AG
摘要:Organic solid solution pigments are prepared and conditioned by treating a mixture of their components, after synthesis but preferably without or with only partial drying, in a mixture of from 0 to 30% by weight of an organic liquid having a dipole moment μ of 2.8–6.0·10 −18 .esu (2.8 to 6.0 debye units) and from 70 to 100% by weight of water in an agitated media pearl mill having a specific power density of at most 2.0 kj·s −1 per liter of grinding space. Drying the starting components is especially suitable in the case of only slightly agglomerating, easy to wet pigments of specific surface area from 1 to 25 m 2 /g. The method gives excellent results, and is flexible and also much simpler than known methods.

摘要:Organic pigments are conditioned by treating them, after synthesis but preferably without or with only partial drying, in a mixture of from 1 to 30% by weight of a neutral, polar liquid having a dipole moment μ of 2.8-6.0? 10 −18 esu (2.8 to 6.0 debye units) and from 70 to 99% by weight of water in an agitated media pearl mill having a specific power density of at most 2.0 kJ s?−1 per liter of grinding space. Drying is especially suitable in the case of only slightly agglomerating, easy to wet pigments of specific surface area from 1 to 25 m 2 /g. The method gives excellent results, and is flexible and also much simpler than known methods.
