Further, Test Example is described.
[0053]
Test Example 1
Twenty (20) ml of each of the liquid agrochemicals obtained in the Preparation Examples 1 to 25 and the Reference Preparation Examples 1 to 11 was put into a glass tube, and kept at 0°C. Each of the liquid agrochemicals was kept for 7 days, followed by checking whether there is any crystal precipitation in each of the liquid agrochemicals.
In the result, no crystal precipitation was found in the present agrochemicals obtained in Preparation Examples 1 to 25 and the liquid agrochemicals obtained in Reference Preparation Examples 3, 6 and 8. On the other hand, the crystal precipitation was found in the liquid agrochemicals obtained in Reference Preparation Examples 1, 2, 4,5,7, 9, 10 and 11.
[0054]
Test Example 2
The following test was conducted using the present agrochemicals obtained in Preparation Examples 1 to 25 and the liquid agrochemicals obtained in Reference Preparation Examples 1 to 11.
Ninety nine (99) ml of CIPAC standard water D (hardness: 342 ppm) at 30°C was put in a 100 ml measuring cylinder with a stopper. One (1) ml of the testing liquid agrochemical was dropped slowly from a height of approximately 8 cm above the surface of the water, and the measuring cylinder was then stoppered. The measuring cylinder was inverted by 180 degrees in 1 second and then returned into its original position in 1 second. After repeating this operation 10 times, the measuring cylinder was allowed to stand in a thermostat chamber at 30°C for 2 hours. Thereafter, state of the liquid in the measuring cylinder was visually observed to evaluate the emulsion stability.
In the result, the liquid containing each of the present agrochemicals obtained in Preparation Examples 1 to 25 and the liquid agrochemicals obtained in Reference Preparation Examples 1,2,4, 5, 7,9, 10 and 11 were kept in a homogeneous emulsified state. On the other hand, the crystal precipitation was found on the bottom face of the cylinder in the liquid containing each of the liquid agrochemicals obtained in Reference Preparation Examples 3, 6 and 8.
