ABSTRACT:
In a preferred embodiment, a high-yield method producing novel water soluble triazone compositions having a typical analysis as follows, percentages being based on the total weight of the reaction product: urea at about 17.5%; MMU at about 3.4%; MDU at about 1.0%; HMT at about 4%; water soluble triazone at about 48%; produced by a novel method in which ammonia/HCHO mole ratio is about 0.3, and in which percentage ammonia added and reacted during the initial reaction is about 4.5% by weight of total reactants, initial cooking is for about 45 minutes, followed by final cooking for about 10 minutes, both initial and final cooking are at about 90 degrees Centigrade, at a nitrogen content of about 28%, at an initial cooking-pH maintained immediately after ammonia addition, at about pH 9, and at a lower pH during the final cooking resulting from termination of adding further potassium hydroxide, the optimum mole ratio during the process, of reactants urea, formaldehyde and ammonia, for example, being about 0.9:1:0.30; otherwise, the method is a two stage-cooking procedure in which urea and/or particular substituted urea is reacted with particular aldehyde(s) and ammonia and/or particular primary amine(s). Novel soluble triazone compositions include novel soluble triazone compounds made from ammonia or from amines such as 2-amino-2-methyl-1-propanol, tris(hydroxymethyl) amino methane, and 2-amino-2-ethyl-1,3 propanediol. Typical novel water-soluble triazone include 1-3, diethyl triazone, 1,3,4,5,6 pentamethyl triazone, 1-3 dimethyl triazone, 4-6 dimethyl triazone, 1,3 dimethyl, 5, hydroxyethyl triazone, 4,6 dimethyl, 5, hydroxyethyl triazone, and 4,6 diethyl triazone. These novel triazones are applied to crop foliage and/or vegetation foliage and/or sod, by liquid foliar spraying after conventional dilution of the product sufficiently for effective foliar spray, utilizing any desired and/or conventional spraying apparatus or machine.
