Claim 2
Independent Claim
54 words
A METHOD FOR THE PRODUCTION OF PEROXYTITAMIUM COMPLEXES WHICH COMPRISES REACTING TITANIUM SULFIDE WITH AN ORGANIC HYDROPEROXIDE SELECTED FROM THE GROUP CONSISTING OF TERTIARY BUTYL HYDROPEROXIDE, CYCLOHEXYL HYDROPEROXIDE, ETHYKVENZENE HYDROPEROXIDE, CYCLOHEXYL HYDROPEROXIDE AND CUMENE HYDROPEROXIDE, AT A PH OF BELOW ABOUT 1.5 AND A A TEMPERATURE IN THE RANGE OF FROM 0* TO 100*C.
Claim 3
Dependent Claim
14 words
The method according to claim 1 wherein the titanium sulfate has the formula TiOSO4.H2SO4.8H2O.
Claim 4
Dependent Claim
60 words
The method according to claim 1 wherein the titanium compound is titanium sulfate having the formula TiOSO4.H2SO4.8H2O and the reaction is carried out in an aqueous medium with the weight ratio of titanium sulfate to water being in the range of from 1: 0.2 to 1:20 and at a temperature in the range of from 20* C. to 80* C.
Claim 5
Dependent Claim
22 words
