CORRELATION STRUCTURE-ACTIVITY IN THE BLEACHING PROPERTIES OF PERACETYLATED CARBOHYDRATES

Low temperature bleaching systems involving sodium perbot-rate and an activator such as tetra acetyl ethylene diamine (TAED), with peracetic acid formation, are commonly used in Europe. Environmentally friendly bleaching agents such as carbohydrate derivatives (mono, oligo, anhyd ro saccharides, polyols and amino sugar acetates) could also be good p roducts with bleaching activator properties. Correlation structure-rea ctivity was established; active acetyl groups were identified for each type of molecule in order to understand the effect of their nature an d configuration, and to determine the role of neighbouring groups.
