The invention relates to a process for the preparation of new Phosphonsaeuremonoestersalzen, which are distinguished by an excellent fungicidal activity. For example, by reacting a mixture of dimethyl phosphite and methanol with a mixture of 3-isononyloxypropylamine, 3-isononyloxypropylammonium methylphosphonate is obtained. Other compounds prepared according to the invention are 3-methoxypropyl-ammonium-ethyl-phosphonate, 3-butoxy-propyl-ammonium-ethyl-phosphonate or octadecyl-ammonium-ethyl-phosphonate. |
