The present invention relates to phosphorylated polyphenols, preferably tannins that, unlike their unphosphorylated counterparts, do not suffer from relatively low stability, resulting in an activity that is relatively short in time, and/or that do not result in yellowing of materials therewith such as textiles or polymers. The present invention further relates to a simple, cheap and environmentally friendly way of preparing these compounds. The phosphorylation process of the invention can be extended to simple phenolic compounds as well, as long as these have at least one accessible hydroxyl group. The phosphorylated compounds according to the invention can be used as antioxidants, as radical scavengers, as complexating agents for metals and proteins, as antibacterials or antiallergenic compounds, and as agents to flock textile.
本发明涉及磷酸化多酚,优选为单宁,与其未磷酸化的对应物不同,它们不会因相对稳定性较低而导致活性时间相对较短和/或不会导致材料变黄,例如纺织品或聚合物。本发明还涉及一种简单、廉价和环保的制备这些化合物的方法。本发明的磷酸化过程也可以扩展到简单的酚类化合物,只要它们至少有一个可接近的羟基。根据本发明磷酸化的化合物可用作抗氧化剂、自由基清除剂、金属和蛋白质络合剂、抗菌或抗过敏化合物以及用于絮凝纺织品的剂。
