Results and discussion

Any other information on results incl. tables

A determination of water solubility was not possible for the following reasons:

1. When preliminary tests were performed, disappearance of the 2 phases was observed on prolonged standing.

2. A reduction of the stirring time to 4 hours and immediate analysis of the content showed that 1,3-dichlorobut-2 -ene content decreased by 26% between the first and eighth injections.

3. In a subsequent main experiment using 10 times the originally weighed-in amount of test material, the mixture was homogeneous after half of the prescribed stirring time, which indicated hydrolysis and solubilization.
