Abstract
A study has been made of the stability of potassium ethyl xanthate in solutions containing alkyltrimethyl ammonium halides. It has been shown that the presence of these compounds leads to an increased rate of decomposition, if the solution is in contact with an atmosphere that contains oxygen and its pH is between 6 and 12. Under other conditions, the stability of the xanthate is unaffected by the presence of the co‐solute. It is concluded that the quaternary ammonium compounds catalyse reaction between oxygen and xanthate, and it suggested that at least two different types of oxygenative reaction take place.
