PROCESS FOR THE PREPARATION OF PHOSPHORIC OR THIOPHOSPHORIC ACID ETHYLENIMIDES

PROCESS FOR THE PREPARATION OF PHOSPHORIC OR THIOPHOSPHORIC ACID ETHYLENIMIDES

The invention is used for the improvement of the method for the synthesis of phosphoric (or thiophosphoric) N,N'-di(ethylenimyde)-N''-methyl amide acid and phosphoric (or thiophosphoric), N,N',N''-triethylenimyde acid. The strong ant leucosis and chemical sterilising ef...

description The invention is used for the improvement of the method for the synthesis of phosphoric (or thiophosphoric) N,N'-di(ethylenimyde)-N''-methyl amide acid and phosphoric (or thiophosphoric), N,N',N''-triethylenimyde acid. The strong ant leucosis and chemical sterilising effects, distinguish the mentioned compounds. The known methods of production use very toxic concentrated ethyleneimine. In this invention, the attenuated hydrated solution of ethyleneimine is used for synthesis. This compound is received by the cyclisation of "β-aminoethylsulphur" acid, is a solution of caustic soda, simultaneously removing the solution of ethyleneimine from the medium of the reaction by distillation. Chloranhydrydes of phosphoric or thiophosphoric acids are added to a hydrated solution of ethyleneimine and the reaction takes place in a trans-phasel medium. When this method is used, the output of the product reaches 75-87%.
