Technology Process of disodium salt of N-nitrosulfanilic acid

There total 2 articles about disodium salt of N-nitrosulfanilic acid which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 90.0%

tetranitromethane (509-14-8) + 4-aminobenzene sulfonic acid (121-57-3,856062-06-1) → disodium salt of N-nitrosulfanilic acid (109885-37-2) + trinitromethane; sodium salt

Guidance literature:

With sodium hydroxide; In water; at 25 ℃; for 30h;

Reference yield: 66.0%

tetranitromethane (509-14-8) + sodium sulfanilate (515-74-2) → disodium salt of N-nitrosulfanilic acid (109885-37-2) + trinitromethane; sodium salt

Guidance literature:

With sodium hydroxide-boric acid buffer; at 25 ℃; Product distribution; pH= 12, other temperature (50 deg C), other pH (9, 10, 11);

Reference yield:

disodium salt of N-nitrosulfanilic acid (109885-37-2) → 2-nitroaniline-4-sulfonic acid (616-84-2)
