Abstract
Organothiophosphorous compounds, e.g., Merphos, which contain or develop malodorous mercaptan impurities during storage, are protected against such odor development by the addition of minor amounts (0.1 to 10%) of a ketone, especially in the presence of a catalyst such as cuprous chloride or p-toluene sulfonic acid in a concentration range of 0.01 to 0.1%. Formulated products are also claimed.
