Abstract
Inventia se refera la procedeele de obtinere a compusilor organici, in particular la un procedeu de obtinere a acizilor N,N-dimetiltioureidobenzoici, care pot fi utilizati in calitate de fungicide, nematocide, regulatori de crestere a plantelor sau in sinteza organica. Procedeul, conform inventiei, include interactiunea unui acid aminobenzoic nesubstituit sau substituit cu disulfura de tetrametiltiuram la incalzire in apa si solutie apoasa de dimetilamina in calitate de activator, la un raport molar initial al reagentilor de 1:(0,75…1):(0,5...1) si temperatura de 65…80°C, monitorizarea reactiei prin metoda cromatografiei in strat subtire, distilarea disulfurii de carbon formate, alcalinizarea ramasitei pana la un pH=9, filtrarea sulfului si a altor impuritati, acidularea filtratului pana la un pH=2...3 si izolarea produsului de reactie prin cristalizare la rece.
