| abstract | Process for the production of a compound comprising potassium phosphite comprising the steps of (a) reacting carboxylic acid of the formula R-(C(=O)OH)n with phosphorous trichloride (PCl3) towards a mixture comprising phosphorous acid (H3PO3) and acid chloride of the formula R-(C(=O)Cl)n; wherein R is a linear or branched alkyl or alkanediyl group with 1-20 carbon atoms and n is 1 or 2, (b) subjecting said mixture to a separation step, thereby obtaining (i) a fraction comprising crude phosphorous acid (H3PO3) and (ii) a fraction comprising acid chloride, (c) combining water, a potassium compound selected from KOH, KHCO3 and K2CO3, and the fraction comprising crude phosphorous acid, thereby forming an aqueous solution comprising potassium phosphite, and (d) removing organic compounds from said aqueous solution. |
