Hordhac faahfaahsan
3-Nitrobenzoic acid waa xarun kiimiko ah oo leh qaaciddada molikaulal c7h5no4. Waxaa sidoo kale loo yaqaanaa m-nitrobenzoic acid. Waa kuwan qaar ka mid ah qodobbada muhiimka ah ee ku saabsan 3-nitrobenzoic acid:
Guryaha jireed:3-Nitrobenzoic acid waxay u muuqataa sida kiristaalo huruud ah ama budo. Waxay leedahay culeys molikal ah oo ah 167.12 garaam halkii mool. Waxay leedahay dhibic dhalaal ah oo qiyaastii ah 140-142 ° C oo si isdaba joog ah ayaa loogu milatanayaa biyaha.
Guryaha kiimikada:3-Nitrobenzoic acid waxaa ku jira koox nitro2 ah (-no2) ku dhegan giraanta benzene. Waa xaraashka udgoon ee loosoogo. Joogitaanka kooxda Nitro ayaa ka dhigaya koox ka soo horjeedda elektaroonigga ah, oo saamaynaya falcelinta moolule.
Synthesis:3-Nitrobenzoic acid waxaa lagu qiyaasi karaa habab kala duwan. Hal hab guud ayaa ah falcelinta nitration ee loo yaqaan 'Benzoic acid', halkaas oo koox nitro2 ah (-no2) lagu soo bandhigo booska meta (3-mowjad) giraanta benzene.
Codsiyada:3-Nitrobenzoic acid waxaa si weyn loogu istcimaalaa inuu yahay mid dhexe oo isku-darka ah ee dawada, dawada, hawo-mareenka, iyo kiimikooyinka kale. Waxay mari kartaa jawaab-celinta sida dhimista, edbinta, ama ku beddelashada si loo bixiyo xeryo kala duwan.
Ka taxaddarada amniga:Sida xarun kasta oo kiimiko ah, talaabooyin caafimaad oo sax ah waa in la qaataa marka la maareeyo 3-nitrobenzoic acid. Waxay sababi kartaa maqaarka iyo cuncun indhaha, iyo neefsashada ama soojiidashada waxay noqon kartaa waxyeello. Waxaa lagula talinayaa in la isticmaalo qalab ilaalin ku habboon, ka shaqee meel hawo wanaagsan leh, oo raac tilmaamaha amniga ee kaydinta iyo tuurista.
Guud ahaan, 3-nitrobenzoic acid waa xarun kiimiko muhiim ah oo loo adeegsado codsiyada warshadaha ee kala duwan sababta oo ah fal-galkiisa oo kala duwan oo loo isticmaalo mid dhexe oo dhexdhexaad ah isku-darka dabiiciga ah.
