piav qhia luv luv:

Mas siv rau kev tsim nitro tebchaw, azo dyes, mordants rau dyeing ntaub, tshuaj dawb tso tus neeg sawv cev, hlau kho tus neeg sawv cev thiab kev lag luam kws
Downstream siv lub ntsiab ntawm cov tshuaj, dyes, tshuaj, tiv thaiv tshuaj, tshuaj pleev ib ce hlau (kev tiv thaiv xeb), kws tshuaj intermediates, tshuaj tua kab intermediates, tshuaj pleev xim intermediates, tshuaj tua kab mob, nitromethane, ethylene glycol.

Sodium nitrite feem ntau yog siv los ua stabilizer thiab ntxiv rau hauv kev lag luam khoom noj, thiab sodium nitrite tseem siv los ua cov tshuaj dawb thiab zas xim. Nws tuaj yeem siv los tsim cov khoom lag luam yooj yim, kua qaub ua si, cov khoom siv ncaj qha, cov tshuaj pleev xim av, diazo thiab azo dyes. Lwm qhov siv rau sodium nitrite suav nrog kev tsim cov tshuaj tua kab, tshuaj tua kab organic, luam tawm ntawm cov hlau nrum thiab cov hlau, ua cov tshuaj tiv thaiv polymer, tshuaj tua kab mob, roj nplua nyeem, roj ua, pulp thiab ntawv, kev lag luam thiab tsev huv, thiab Tsim cov khoom nyoos rau caffeine thiab saccharin.

Sodium nitrite (NaNO₂) yog cov roj ntsha inorganic ntsev tsim los ntawm kev sib xyaw ntawm nitrite ion thiab sodium ion. Sodium nitrite yog yooj yim rau deliquesce thiab soluble hauv dej thiab kua ammonia. Nws cov kua aqueous yog alkaline thiab nws pH yog li ntawm 9. Nws yog me ntsis soluble hauv organic solvents xws li ethanol, methanol thiab ether. Sodium nitrite muaj qab ntsev thiab yog siv los ua cov lus cuav ntsev. Sodium nitrite yuav hnov mob nrog oxygen ua cov sodium nitrate thaum raug rau huab cua. Yog hais tias rhuab saum toj no 320 ° C, nws yuav decompose los tsim oxygen, nitrogen oxide thiab sodium oxide. Sib cuag nrog cov organic teeb meem yooj yim mus hlawv thiab tawg. Vim tias nws qab qab ntsev thiab tus nqi qis, feem ntau yog siv cov khoom tsis muaj txiaj ntsig rau lub rooj ntsev thaum ua zaub mov tsis raug cai. Vim tias sodium nitrite muaj tshuaj lom, cov zaub mov muaj ntsev muaj teeb meem ntau rau tib neeg thiab carcinogenic.
