In order to selectively desulfurize gases, a physically-acting washing product is used, the basic structure of which is a heterocycle having five or more ring atoms and two heteratoms, one of which is nitrogen and the other is nitrogen. oxygen or nitrogen. In closed chains with an even number of elements, heteroatoms take one of positions 1,2 to 1, n / 2, and in closed chains with an odd number of elements, they take one of positions 1,2 to 1, (n-1) / 2. Otherwise, nitrogen heteroatoms are linked in the closed chain by a double or single bond, and are substituted by organyls. |
