摘要
研究了一类新型光漂剂———磺酸基卤素铝酞菁的去污漂白性能。从不同试验中得到该类光漂剂在常温日光条件下对酒渍、茶渍、咖啡渍等顽渍具有很好的去污漂白作用,去污值分别可提高10.8%、12.5%及15.9%。通过与过硼酸钠及过碳酸钠的去污对比试验,突出了该类光漂剂在温和条件下即具有很好的漂白性能,有望代替传统漂白剂。与洗涤剂中的荧光增白剂有相互增效作用,洗涤剂中盐类能改善光漂剂的性能。通过它的光降解试验,初步表明该类光漂剂易于光降解。
The bleaching and detergency performance of a new sort of photoactivator, sulfonated phthalocyanine of aluminum containing halogen substituents was studied. Results from various experimental tests showed that this photoactivator has good bleaching and detergency effect on stubborn stains such as wine, tea and coffee under ambient temperature and sunlight condition and the detergency of standard laundry powder formulated with the photoactivator can be upgraded against the same standard laundry powder without the photoactivator as 10.8%, 12.5% and 15.9% respectively. Results from comparison tests against conventional bleaching agents, sodium perborate and sodium percarbonate showed that the photoactivator can achieve good bleaching effect under mild conditions and can be a valuable substitute for the conventional bleaching agents. This photoactivator displays mutual synergism with optical brighteners used commonly in detergent product while the salts, such as sodium sulfate and sodium tri - polyphosphate formulated in the laundry powder can enhance the performance of the photoactivator. Preliminary test showed that the photoactivator is photodegradable.
