10 g (0.034 mol) of 1-(6-chloropyridin-2-yl-oxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-butan-2-one (Example 1) were dissolved in 50 ml of acetone, and a solution of 8 g (0.027 mol) of naphthalene-1,5-disulphonic acid in 50 ml of acetone was added. The salt which precipitated after some time was filtered off and dried. 14 g (94% of theory) of 1-(6-chloropyridin-2-yl-oxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-butan-2-one naphthalene-1,5-disulphonate of melting point 212°-215° C. (decomposition) were obtained.
