Abstract
Procedimiento para la obtención de combinaciones arsenobenzólicas asimétricas caracterizado porque del modo conocido se reduce en arsenobenzol aimétrico el ácido 3-di (β,γ-dioxi-propil)-amino-4-oxi-benzol-1-arsónico y juntamente ácido benzoxazol-2-mercaptopropionico-5-arsónico pudiendo realizarse también la reacción mediante productos intermedios de ácidos arsónicos como óxido de arsina y/o arsinas y porque el producto de la reacción se convierte dado el caso en una sal soluble en agua o porque las dos combinaciones arsenobenzólicas simétricas 3,3'-arsenobenzoxazol-2,2'-di(ácido mercaptopropiónico) especialmente en forma de sus sales de sodio se transforman en disolventes adecuados en el arsenobenzol asimétrico y el producto de la reacción se convierte dado el caso en una sal soluble en agua.Procedure for obtaining asymmetric arsenobenzole combinations characterized in that, in a known way, 3-di (β, γ-dioxy-propyl) -amino-4-oxy-benzol-1-arsenic acid and together benzoxazole-2 acid are reduced in symmetric arsenobenzole -mercaptopropionic-5-arsenic, the reaction can also be carried out by means of arsenic acid intermediates such as arsine oxide and / or arsines and because the reaction product is converted, if necessary, into a water-soluble salt or because the two symmetric arsenobenzole combinations 3,3'-arsenobenzoxazole-2,2'-di (mercaptopropionic acid), especially in the form of its sodium salts, are converted into suitable solvents in the asymmetric arsenobenzole and the reaction product is optionally converted into a salt soluble in Water.
