|
摘要
为提高分散染料生产的自动化水平,从重氮化反应过程和偶合反应过程2个方面研究了分散染料自动连续化生产的新工艺。与传统间歇式生产相比,采用自动连续化新工艺生产的分散紫93∶1和分散蓝291∶3,其液相色谱(HPLC)纯度分别提升1.16%、0.87%,染料收率分别提高2.06%、2.07%,染料的高温分散稳定性过滤时间均为A级,新工艺生产的分散紫93∶1的残余物等级为4级,高于传统间歇工艺生产分散紫93∶1的3~4级,涤纶染色织物的色光和各项染色牢度等测试结果相近。自动连续化生产新工艺的应用,使得染料滤饼母液水的量减少20%以上,提高了水的重复利用率,避免了传统间歇式生产中各种问题的出现,稳定了染料生产的产品质量,同时,提高了企业的环保效益和经济效益。
In order to improve the automation level of the production of disperse dyes,a new automatic and continuous production process of disperse dyes was investigated from the aspects of diazotization process and coupling reaction process. Compared with the conventional batch production process,the high performance liquid chromatography( HPLC) purity of the C. I. disperse violet 93∶ 1 and the C. I. disperse blue 291∶ 3 produced by the new automatic and continuous production process was improved by 1. 16%and 0. 87%,respectively,and their yield has improved by 2. 06% and 2. 07% respectively,the filtration time levels of the high temperature dispersity are all of the A-grade. The residue levels of the C. I.disperse violet 93∶ 1 produced by the new automatic and continuous production technology are 4 levels,which is a little higher than that of the C. I. disperse violet 93 ∶ 1 produced by the traditional batch production process( 3- 4 grade). The color and various color fastness of the dyed polyester fabric by new process are similar to that produced by traditional process. The application of the new automatic and continuous production technology of disperse dyes reduces more than twenty percent dosage of the filter cake mother liquor,improved the repeating utilization factor of the water,avoided various problems existed in the traditional batch production process,and stabilized the quality of the disperse dyes. Meanwhile,the environmental and economic benefits of the enterprise were enhanced.
