METHOD OF REUSING ORGANOARSENIC SUBSTANCES FROM STATE MORTUARY CONTAINING 10-CHLORO-5,10-DIHYDROPHENARSINE

摘要

FIELD: toxic substances disposal. SUBSTANCE: industrial-grade product containing irritant 10- chloro-5,10-dihydrophenarsine (admsite) is treated with gaseous hydrogen chloride at 170 to 325 C while simultaneously distilling off arsenic trichloride. Remaining reaction mass is dehydrochlorinated to isolate diphenylamine. Vat residue is additionally treated with hydrogen chloride while simultaneously residual arsenic trichloride is blown off and stream is returned into primary process. EFFECT: increased degree of conversion of toxic substance and enabled production of useful products. 2 cl, 1 tbl, 4 ex
