- the yields of di-boric acid diesters in the distillation are usually> 99%.
- the following examples are intended to illustrate the subject matter of the invention without, however, limiting it to it.
- the round bottom flask was tightly closed with a septum. There was an opening in this septum in which a Teflon tube was attached, which was passed into a vertically placed 50 ml burette filled with silicone oil and calibrated to 0.1 ml. By scaling the burette, the amount of carbon dioxide evolved by the decomposition of the di-carbonic acid diester could be read.
- the flask was rapidly lowered into a constant temperature oil bath (stirred at 500 rpm) as indicated in Tables 1 to 6 for the respective experiment.
- the immersion depth of the piston was 2.0 cm.
- the gas volume was read.
- the gas volume is a measure of the degree of decomposition of the di-carbonic diesters in CO 2 . Conversely, it reflects the degree of stabilization by the tested additives.
- Dimethyl dicarbonate was stored at room temperature. As a measure of the decomposition, the dimethyl carbonate content was determined by GC. Without the addition of a stabilizing agent, the dimethyl carbonate content of the sample after 3 months was 1090 ppm.
- the experiment was repeated but about 5 ppm phosphoric acid was added.
- the test series was carried out with 10 different samples.
- the dimethyl carbonate content was in this case after 3 months on average at only 210 ppm.
