PCT No. PCT/GB93/01975 Sec. 371 Date Apr. 21, 1995 Sec. 102(e) Date Apr. 21, 1995 PCT Filed Sep. 20, 1993 PCT Pub. No. WO94/07855 PCT Pub. Date Apr. 14, 1994Organic peracids supported on inorganic macromolecular supports and a process for preparing them are provided. The peracids have general chemical formulae: Q-O-Si-A-NR-X-CO3H (I) wherein Q represents the inorganic support, A is an alkylene or arylene group, R represents hydrogen, alkyl or an aryl group and X represents an optionally substituted alkylene or arylene group, or Q-O-Si-A-N X'-CO3H (II) where Q and A are as defined above, and X' represents an optionally substituted alkylene or arylene group. The peracids have improved stability and recovery characteristics compared with those of the prior art.
