METHOD OF OBTAINING COPPER [N,N'-BIS(DIMETHYLAMINOMETHYL)-THIOUREA OXALATE]SULFATE PENTAHYDRATE AS PREPARATION FOR FIGHTING SOIL AND SEED-SURFACE INFECTION Russian patent published in 2014 - IPC C07C275/14 A01N33/04 A01N59/20 A01P1/00

Abstract RU 2536404 C2

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining copper [N,N'-bis(dimethylaminomethyl)-thiourea oxalate]sulfate pentahydrate of general formula (1) as preparation for fighting soil and seed-surface infection. Essence of method consists in interaction of N,N,N',N'-tetramethylmethylenediamine (bisamine) with thiourea in mole ratio bisamine:thiourea=(20-30):10, at temperature 30-50°C for 1.5-2.5 h with further removal of bisamine excess and addition of water solutions of oxalic acid (COOH)₂ and copper sulfate (CuSO₄·5H₂O) in equimolar to thiourea quantity and mixing for 10 min.

EFFECT: output of copper [N,N'-bis(dimethylaminomethyl)-thiourea oxalate]sulfate pentahydrate of general formula (1) constitutes 90-99%.
