由EP-A-238446和EP-A-321393已经已知一种荧光增白混合物,它含有上述的双苯乙烯基化合物I和II,其重量比是80.25∶19.75和80∶20。但是,事实已表明,这种混合物在应用技术性能上还存在着不利之处。
本发明的目的是提供以双苯乙烯基化合物为基础的新增白混合物,它使用简单,具有有利的应用技术性能,特别是具有高的白色度。
申请人发现这种前面已经详细描述的增白混合物可以实现这一目的。
这种新的增白混合物包含结构式为I和II的双苯乙烯基化合物,其含量是混合物重量的75~100%(重量),优选地是80~100%(重量),特别优选地是85~100%(重量)。
在工业上特别感兴趣的是结构式为I和II的双苯乙烯基化合物含量是增白混合物重量85~90%(重量)的混合物。
在本发明的增白混合物中,结构式为I和II的双苯乙烯基化合物的重量比为10∶90~70∶30,优选地是20∶80~60∶40,特别优选地是30∶70~60∶40。
在工业上特别感兴趣地是这种增白混合物,即其所含结构式为I和II的双苯乙烯基化合物的重量比为40∶60~50∶50,优选地是大约45∶55。
例如,这种新增白混合物可以由单个组份按适当重量比例混合而制成。单个组份可以按照已知的方法得到。例如,氰基膦酸烷脂可以在酮碱介质中在一种惰性有机稀释剂中与对苯二醛反应。
本发明另外的内容是增白剂的配制品,它包含有水和上面已详细描述的增白混合物以及助剂,其中按配制品重量为基,增白混合物含量为3~25%(重量),优选地是5~15%(重量),助剂含量为5~60%(重量),优选地是5~52%(重量)。
例如,合适的助剂是阴离子或非离子性的分散剂,其可选自脂肪醇和氧化乙烯加成物,高的脂肪酸或者烷基苯酚或乙二胺-环氧乙烷-环氧丙烷加成物,或者是这种分散剂,如在DE-A-2 745 449中描述的分散剂,N-乙烯基吡咯烷酮和3-乙烯基丙酸的共聚物,如乙二醇、丙三醇或山梨醇的保水剂,或者是杀虫剂。
优选的增白配制品除水外还含有占所制配制品重量的3~25%(重量),优选地为5~15%(重量)的上面已详细描述的增白混合物,以及3~12%(重量)的阴离子或非离子性分散剂,1~15%(重量)的N-乙烯基吡咯烷酮和3-乙烯基丙酸的共聚物和1~25%(重量)的其它助剂(例如;保水剂或者杀虫剂)。
通过适当的方式本发明的增白混合物可适合于合成、半合成或者天然聚合物材料的荧光增白,优选的是适合于聚酯,特别是聚酯纤维的荧光增白。它们将较低的固色或褪色温度与有益的应用性能结合起来。此外,其还可批量生产。
下面用实施例来进一步详细描述本发明。
发光混合物的制备
a)在1100ml的N,N-二甲基甲酰胺中加入201g(1.47mol)对苯二醛(98.45%(重量)的)和402.7g(1.47mol)3-氰基苄基膦酸二乙酯(91.7%重量)。在30℃时,在4h内向这个混合物中添加279.8g(1.54mol)、30%(重量)的在甲醇中的甲醇钠溶液,然后,在30℃下搅拌2h,并且首先加入434.9g(1.54mol)4-氰基苄基膦酸二乙酯,最后加入另外的279.8g(1.54mol)30%(重量)的在甲醇中的甲醇钠溶液。然后,在30℃下搅拌4h,冷却到25℃,去掉产生的沉淀物,用甲醇洗三次,每次用量为500ml,用1650ml水清洗一次,然后干燥。
b)在1100ml的N,N-二甲基甲酰胺中加入201g(1.47mol)98.45%(重量)的对苯二醛和395.7g(1.47mol)94%(重量)的2-氰基苄基膦酸二乙酯。在30℃下,3h内向这个混合物中添加279.8g(1.54mol)30%(重量)的甲醇中的甲醇钠溶液。然后,在30℃下,搅拌1h,并且,首先加入434.9g(1.54mol)的4-氰基苄基膦酸二乙酯,最后加入另外的279.8g(1.54mol)30%(重量)的甲醇中的甲醇钠溶液。在30℃下,搅拌1h之后,冷却到25℃,去掉产生的沉淀物,用甲醇清洗三次,每次用量为500ml,然后用1650ml的水清洗一次,并使之干燥。
