Abstract

1. Двухкомпонентный поглотитель сероводорода, представляющий собой смесь соединений ! ! в соотношении (Ia):(Iб)=9:1 ! 2. Способ получения поглотителя сероводорода, заключающийся в том, что этаноламин и гуанидин сернокислый, растворенный в n-BuOH, взаимодействуют с параформальдегидом при мольном соотношении HOCH2CH2NH2:NHC(NH2)2:CH2O равное 0,9:0,1:3,6, температуре 70°С и постоянном перемешивании в течение 2 ч с последующим удалением растворителя.1. A two-component hydrogen sulfide absorber, which is a mixture of compounds! ! in the ratio (Ia) :( Ib) = 9: 1! 2. A method of producing a hydrogen sulfide scavenger, in which ethanolamine and guanidine sulfate, dissolved in n-BuOH, are reacted with paraformaldehyde at a molar ratio of HOCH2CH2NH2: NHC (NH2) 2: CH2O equal to 0.9: 0.1: 3.6 at a temperature of 70 ° C and constant stirring for 2 hours, followed by removal of the solvent.
