A sea-water algicidal composition containing a triazine of the group comprising 2-methylthio-4-cyclopropylamino-6-(.alpha.,.beta.-dimethylpropylamino)-s-triazine (I); 2-methylthio-4-cyclopropylamino-6-t-butylamino-s-triazine (II); and 2-methylthio-4-ethylamino-6-(.alpha.,.beta.-dimethylpropylamino)-s-triazine.
摘要:
A mixture of the compound of the formula II--CH.sub.2 CONH.sub.2 (I)with amines or quaternary ammonium compounds is used to control, in particular, micro-organisms in water and in aqueous systems.According to the invention, the compound of the formula I can also be employed without additional biocides for the control of micro-organisms in certain selected systems. These include, for example, swimming pools, ponds, cooling water, cutting and drilling oils, cellulose compositions, glues and starch pastes.Agents which contain the biocide mixture or the compound of the formula I, together with auxiliaries, are claimed.
