Abstract
Способ очистки хлористого водорода в производстве хлорангидридов ароматических кислот от органических примесей путем вымораживания, отличающийся тем, что, с целью повышения степени очистки, вымораживание ведут при (-15) - (+50C), после чего газ пропускают через слой зернистого пористого материала с размером частиц 1 - 3 мм со скоростью 0,03 - 0,3 м/с.The method of purification of hydrogen chloride in the production of aromatic acid chlorides from organic impurities by freezing, characterized in that, in order to increase the degree of purification, freezing is carried out at (-15) - (+ 50C), after which the gas is passed through a layer of granular porous material particles 1 - 3 mm with a speed of 0.03 - 0.3 m / s.
