Abstract
Inventia se refera la un procedeu pentru obtinerea 0,0-dimetil-S-(ftalimidometil)-ditiofosfatului, conform caruia se trateaza un amestec, constituit din acid sulfuric 0,0-dimetil-ditiofosfat de amoniu în exces de 5...30% si cu N-hidroximetilftalimida, la temperatura de 20....50 degree C, dupa care reactia se definitiveaza la 20...65 degree C, iar substanta activa obtinuta se extrage din mediu de reactie cu o hidrocarbura aromatica, aleasa dintre benzen, toluen sau xilen sau un solvent alifatic halogent, ales dintre clorura de metilen sau dicloretan.
