Daim ntawv thov

Naphalene-2-sulfonic acid yog ib qho tseem ceeb tshuaj intermediate dav siv nyob rau hauv cov xim, textile, thiab tawv industries. Siv rau kev tsim cov dye intermediates xws li 2-naphthol, 2-naphthol sulfonic acid, 1,3,6-naphthalene trisulfonic acid, 2-naphthylamine sulfonic acid, thiab lwm yam Dehydrogenation catalyst. Reacting nrog formaldehyde tuaj yeem tsim tus neeg sawv cev N (diffusion agent NNO). Naphthalene-2-sulfonic acid kuj tseem siv los ua biochemical reagent thiab sim reagent rau kev txiav txim siab ntawm peptone thiab protein.
