- Another object of the present invention is the stabilization of DikohlenTalkrediestern by adjusting a - compared with high purity Dikohlenquipredestern - increased proton concentration to a pH of below 6.5, preferably to a pH of 6.0 to minus 5.0, and more preferably from 5 , 5 to 0. This can be effected for example by the inventive addition of protic acids in amounts of from 0.01 to 100,000 ppm.
- the measurement of the proton concentration usually takes place in aqueous media via the oxonium ions formed therein.
- the usual characteristic was the pH value.
- the measurement of the pH can be carried out, for example, after suitable sample preparation by titration with suitable bases. The end point of the titration is usually indicated by a color change of an indicator dye.
- the pH measurement can also be done, for example, by electrochemical means. Usually used here are pH electrodes, so-called combination electrodes.
- pH values in organic liquids can often be used to measure a pH very reproducibly.
- Another way of measuring the proton concentration in the case of organic liquids involves sample preparation. For example, in the case of dicarbonic diesters, the proton concentration can be determined after extraction with ultrapure water. In this case, the Dikohlenchurediester is added as organic liquids with little water, mixed well and the phases separated. From the pH of the aqueous phase, the amount of acid originally present in Dikohlenchurediester can be calculated.
- 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 1-4 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 Dikohlenklarediester in CO 2 . Conversely, it reflects the degree of stabilization by the tested additives.
- Additive Stabilizer without HCl 37.0% 65.0% citric acid malic acid 99.5% p.a. water
- the Dikohlen Tarndredimethylester was extracted with a little high-purity water and measured before or after phase separation of the pH value with the glass electrode in this water. Thereafter, the pH was converted to the original dicarbonate volume. This procedure gave identical values and less drift of the pH electrode.
- the solutions were purged with argon at the pH determinations in order to prevent influences of the pH value by carbon dioxide.
