Abstract

Notably concerns the potassic sodium salt of the [alpha], [alpha]', -(1, 2-ethanol diyl diamine)-bis-[2-hydroxy-5-thiobenzene acetic] acid resulting from the reaction between 45 degrees C and 80 degrees C of ethylenediamine, sodium glyoxylate and potassium paraphenol sulphonate, with the addition of glyoxylic acid and caustic soda for 4 hours, with a pH between 9 and 10.Applicable to products used in treating ferric chlorosis in crops
