Fluorescent monomers are described and claimed which are synthesized by reacting a substituted or non-substituted naphthalic anhydride with an amine and with a moiety containing a polymerizable group. Such monomers are useful for the preparation of tagged treatment polymers. Such tagged treatment polymers are useful as scale inhibitors in industrial water systems.

Case 5-14251/ZFO/= 2,4-Diamino-6-halo-5-trifluoromethylpyrimidines having herbicidal activity Abstract 2,4-Diamino-6-halo-5-trifluoromethylpyrimidines of the formula (I) wherein X is a halogen atom, especially chlorine or fluorine, and R1 and R2 independently of one another are each hydrogen, C1-C6-alkyl or C3-C6-cycloalkyl, or together form a C3-C7-alkylene bridge, have outstanding selective-herbicidal properties, and are suitable for controlling weeds in crops of cultivated plants, such as maize, cereal or soya-bean. They are produced by aminating 2,4,6-trihalo-5-trifluoromethylpyrimidine, which for its part is obtainable by fluorination of 2,4,6-trihalopyrimidine-5-carboxylic acid. The 2,4,6-trihalo-5-carboxylic acids are novel intermediates, and are obtained by oxidising 2,4,6-trihalo-2-methyl-, -halomethyl-or -formyl-pyrimidine in sulfuric acid by means of chromium trioxide.
