METHOD OF OBTAINING N, N ' BIS (DIMETHYLAMINOMETHYL) - THIOUREAOXALATE SULFATE OF COPPER OF PENTAHYDRATE AS THE MEANS FOR DEALING VERSATILE BY SOIL AND SURFACE- SEED INFECTION

摘要

1. A process for preparing [N, N'-bis (dimethylaminomethyl) -tiomochevinoschavelevokisly] copper sulfate pentahydrate general formula (1) wherein the N, N, N ', N'-tetrametilmetilendiamin (bisamino) is reacted with thiourea in a molar ratio bisamino: thiourea = (20-30): 10 at a temperature of 30-50 ° C for 1.5-2.5 hours followed by removal of excess bisamino and adding aqueous solutions of oxalic acid (COOH) and copper sulphate (CuSO · 5HO) in an amount equimolar to the thiourea and stirring for 5-10 min at room temperature and atm Sphere davlenii.2.Primenenie [N, N'-bis (dimethylaminomethyl) -tiomochevinoschavelevokisly] copper sulfate pentahydrate as a means for combating soil surface and seed infection
