摘　　要：用硫酸作催化剂制备焦油酚/焦油酚蒸溜产品和木素磺酸的缩合物,然后将缩合物再和另一部份木素磷酸混合。研究了影响缩合的因素。用产物鞣制小块脱灰山羊皮,以它的收缩温度判断鞣剂的鞣性。最后,获得了良好的稳定性和鞣性的鞣剂。The condensation productsof tar phenol/distillate product and ligninsulfonic acid were prepared with sulfuric acid as catalyst,then the condensation products were mixed with auother part of ligninsulfonic acid. Fact effecting the condensation ware studied. The tanning was carried out on small pieces of delimed goat skin,the tanning property of final products was determinde by the shrinkage of tanned leafher.The both products were obtained with tarphenol or its distillate product have good stabality,tanning preperty and others.
