Abstract

1. Способ получения 1,2-бис-(1,5,3-дитиазепан-3-ил)этана формулы (1)отличающийся тем, что предварительно приготовленную при 20°C смесь водного раствора формальдегида и 1,2-этандитиола подвергают взаимодействию с 1,2-этилендиамином в воде при мольном соотношении 1,2-этандитиол:формальдегид:1,2-этилендиамин=2:4:1 при температуре ~20°C и атмосферном давлении в течение 2-4 ч.2. Применение 1,2-бис-(1,5,3-дитиазепан-3-ил)этана в качестве сорбента палладия(II) и серебра(I).1. The method of obtaining 1,2-bis- (1,5,3-dithiazepan-3-yl) ethane of the formula (1) characterized in that the mixture of an aqueous solution of formaldehyde and 1,2-ethanedithiol pre-prepared at 20 ° C is reacted with 1,2-ethylenediamine in water at a molar ratio of 1,2-ethanedithiol: formaldehyde: 1,2-ethylenediamine = 2: 4: 1 at a temperature of ~ 20 ° C and atmospheric pressure for 2-4 hours. 2. The use of 1,2-bis- (1,5,3-dithiazepan-3-yl) ethane as a sorbent of palladium (II) and silver (I).
