摘　　要：本文研究一种新的合成鞣剂及它的制备方法。SRT 复鞣剂为芳香砜桥型缩合物。首先由苯酚合成4.4′-二羟基二苯砜,再与萘磺酸,甲醛和脲在酸性水溶液中反应,得到均相水溶性的共缩合物。它是一种耐光性的白色合成鞣剂,特别实用于鞣制白色革。它与铬盐络合作为矿物鞣革的复鞣剂,尤其是复鞣铬革显得光亮和丰满。This paper research on a new synthetic tanning agent and the method of preparation.SRT retanning agent is aromatic sulfonyl bridge condesation product.At first,4.4-dihydroxy diphenyl sulfone is prepared,and then it reacts with naphthalene sulfonic acid,formaldehyde and urea in an acid agu- eous medium.It will be obtained homogeneous,water-soluble co-condensation products.SRT will be outstandingly suitable as tanning agent for the product- ion of white leather,which is fast to light.It can be complexed with chro- mite salt,this complexes are used as retanning agent for retanning mineral- tanned leather,in particule for brightening and plumpig chrome leather.
