FUNGICIDE COMPOSITIONS CONTAINING AS ACTIVE SUBSTANCE DERIVATIVES OF BENSOIC ACID AND PROCESS FOR PRODUCTION OF THE ACTIVE SUBSTANCE

According to the present invention there are provided fungicidal compositions comprising as active ingredient in an amount of 0.01-80% by weight a new benzoic acid derivative of the general Formula I I wherein R1 and R2 stand for hydrogen, C1-8 alkyl, C2-8 alkenyl or benzyl; R3 represents hydrogen, C1-8 alkyl or C2-8 alkenyl; R1 and R2 may be the same or different; and R3 may be identical with or different from R1 and/or R2. According to the present invention there is provided a process for the preparation of the compounds of the general Formula I which comprises esterifying 4-chloro-3,5-dinitro-benzoic acid with a saturated or unsaturated aliphatic alcohol at a temperature between 20 DEG C. and 120 DEG C.-preferably at 60 DEG -100 DEG C.-in the presence of a solvent as medium and in the presence of a catalyst, and aminating the ester thus obtained with ammonia or the corresponding primary or secondary amine at a temperature between 40 DEG C. and 100 DEG C.-preferably at 60 DEG -90 DEG C.-in the melt or in an inert solvent as medium, in the presence of an acid binding agent; or changing the order of succession of the said two steps and carrying out at first amination and thereafter esterification. A preferred representative of the compounds of the general Formula I is the n-propyl-4-diallylamino-3,5-dinitro-benzoate.
