摘要
以邻硝基苯胺为重氮组分、对羟基苯磺酸为偶合组分,合成邻位含有硝基的偶氮化合物中间体,再利用二氧化硫脲将此中间体还原,制得一种水溶性紫外线吸收剂2-(2-羟基-5-磺酸基苯基)苯并三唑。将该紫外线吸收剂应用于羊毛织物上,并优化上染工艺。研究发现,pH值和紫外线吸收剂的用量对上染率影响较大,处理后的羊毛织物具有较好的紫外线防护效果。
O-nitroaniline and 4-hydroxybenzenesulfonic acid are used to prepare an azo intermediate,which is then reduced by Thiourea S,S-Dioxide to synthesize the target water-solubility UV-absorber 2-（2-hydroxy-5-sulfonicphenyl）benzotriazole.The UV-absorber is applied to wool fabrics and the processing is optimized.The results show that the uptake on wool is largely influenced by both the pH value and amount of UV-absorber applied.The results also reveale that this UV-absorber can obviously improve the UV protective ability of wool fabrics.
