Description
Thionophosphorsäuieester, in denen die Reste zweier Dialkylthionophosphorsäuren über die Sulfoxydgruppe miteinander verknüpft sind, sind bisher nicht bekanntgeworden. Thionophosphoric acid esters, in which the residues of two Dialkylthionophosphoric acids are linked to one another via the sulfoxide group, have not yet become known.
Es wurde nun gefunden, daß diese Stoffklasse aus 0,0-Dialkyldithiophosphorsäure-disulnden folgender allgemeinen Formel:It has now been found that this class of substances consists of 0,0-dialkyldithiophosphoric acid disulndants of the following general Formula:

Vorteilhaft wird dabei die Oxydation der Disulfide mit Wasserstoffsuperoxyd in geeigneten Lösemitteln in schwach saurem Medium bei Temperaturen von 40 bis 70° C durchgeführt. Bewährt hat sich als Lösemittel vor allem Eisessig. Es können aber auch Kohlenwasserstoffe als Lösemittel verwendet werden, wenn z. B. in Gegenwart geringer Mengen Schwefelsäure diese Reaktion durchgeführt wird.The oxidation of the disulfides with hydrogen peroxide in suitable solvents in carried out in a weakly acidic medium at temperatures of 40 to 70 ° C. Has proven itself as a solvent especially glacial acetic acid. However, hydrocarbons can also be used as solvents if, for. Am In the presence of small amounts of sulfuric acid this reaction is carried out.
