由3,3’-二甲氧基-4,4’-二氨基-二苯环乙烷盐酸盐出发,经双重氮化,与2-萘酚-3,6-二磺酸钠及2,8-二羟基萘-6-磺酸钠进行第一、二偶合反应,盐析、过滤、干燥粉碎得本发明弱酸红染料。

Description

弱酸红染料
本发明涉及到一种双偶氮类红色染料。
与本发明最密切相关的已有技术是一种牌号为普拉红3B染料,见染料牵引C、I、Alid Red134,该牌号染料由端士汽巴-嘉基公司、德国拜自公司等生产,其有效成份结构式为:
生产该染料的工艺路线可参见B、I、O、S、FINAL、REPORTNO、1548 Page61,题目名称为SUPRANOL BORDEAUX B,由3;3’-二甲氧基-4;4’-二氨基-二苯环己烷盐酸盐出发,经重氮化再与2;8-二羟基萘-6-磺酸偶合,过滤干燥粉碎得成品,由于普拉红3B的色光等性能已不附合现在市场消费需要,如何研制一种色泽艳红,又具有较好染色性能的染料新品种成为现在较为迫切的课题。
本发明目的就是要提供一种目前尚还缺少的较理想的又能满足市场对色泽艳红要求的弱酸性染料。
本发明所述的弱酸性染料其化合物结构式为

(I)
含有上述结构式(I)的弱酸性红染料在染色实验中被证实,其染色性能优于普拉红3B,色光也较鲜艳、漂亮。附表1.2说明本发明染料与普拉红3B在染色牢度上的比较数据。表1

另,水溶性,吊白性能和扩散性能,本发明弱酸红染料也较普拉红3B好。
由结构式为(I)决定的弱酸红染料,可以通过对通常的双偶氮类染料的制造方法适当修改而获得,例如由3,3’—二甲氧基-4,4’—二氨基-二苯环己烷盐酸盐出发,经双重氮化后与2-萘酚3,6—二磺酸钠进行第一偶合,再与2,8—二羟基萘-6-磺酸钠进行第二次偶合,经过盐析,过滤,干燥粉碎,并可根据需要用硫酸钠等助剂商品化,即得弱酸红染料。该方法与普拉红3B制造方法相比较,前者偶合所用的原料之一,2-萘酚—3.6—二磺酸钠大部分来源于制另一中间体2,8—二羟基萘-6—磺酸钠时所得的付产品,故大大提高了原材料的利用率,降低了原材料的成本。
本发明弱酸红染料宜在中性或弱酸溶中用于羊毛、蚕丝、绵纶织物染包,也可用于混纺品及皮革染色,可在蚕丝或羊毛织物上直接印花。上述弱酸红染料对含氨基类纤维的染色性能均优于普拉红3B,以下提供几个应用实施例。
例1   在中性浴中,绸布染色,染液浓度1%,浴比1%(对织物重)加NaCl(10克/升染液),染色温度在85~90℃,染色时间45分钟,染色绸布并经固色处理(加固色剂)。

例2  在弱酸浴中(PH=5)绸布染色,染液浓度1.0%,浴比1%,染色温度在90~95℃,染色时间45分钟,上染率达93%,并经固色处理(加固色剂)。

例3  在酸性浴中,硫酸2~4%,食盐5~10%,染液浓度1%,将染液加热至40℃,即将用沸蒸馏水浸透羊毛纤维投入染色,于30分钟内使染液温度升到沸腾,续染45分钟,经适当处理,羊毛纤维染上兰光红。
例4  在弱酸浴中(冰醋酸2.4ml/L),六偏磷酸钠1g/L左右,平平加○1.48/L中进行尼龙纺染色可使尼龙纺着色。
