Cov lus qhia ntxaws ntxaws
3-nitrobenzoic acid yog tshuaj sib txuas nrog cov mis molecular c7h5no4. Nws tseem paub tias yog m-nitrobenzoic acid. Nov yog qee cov ntsiab lus tseem ceeb txog 3-nitrobenzoic acid:
Lub cev lub cev:3-nitrobenzoic acid tshwm li daj muaju lossis hmoov. Nws muaj molecular ceeb thawj ntawm 167.12 grams ib mole. Nws muaj lub ntsiab lus melting ntawm txog 140-142 ° C thiab yog sparingly soluble hauv dej.
Tshuaj lom neeg cov khoom:3-nitrobenzoic acid muaj Nitro Group (-no2) txuas rau lub nplhaib Benzene. Nws yog ib qho aromatic carboxylic acid. Lub xub ntiag ntawm Nitro Group ua rau nws hluav taws xob-rho tawm pab pawg, cuam tshuam cov kev sib cuam tshuam ntawm cov molecule.
Synthesis:3-nitrobenzoic acid tuaj yeem ua hluavtaws los ntawm ntau txoj kev. One common method is the nitration reaction of benzoic acid, where a nitro group (-NO2) is introduced at the meta position (3-position) of the benzene ring.
Cov Ntawv Thov:3-nitrobenzoic acid tau siv dav ua ib qho nrab hauv synthesis ntawm cov tshuaj, dyes, agnismicals, thiab lwm yam tshuaj. Nws tuaj yeem yauv tau kev tawm tsam li txo qis, cov khoom siv, lossis hloov mus rau cov lus sib txawv.
Kev Ceev Fwm Kev Nyab Xeeb:Zoo li cov tshuaj sib txuas, kev ntsuas kev nyab xeeb yuav tsum tau coj thaum tuav 3-nitrobenzoic acid. Tej zaum nws yuav ua rau tawv nqaij thiab qhov muag khaus, thiab nqus tau los yog kev haus cawv lossis noj yuav muaj kev phom sij. Nws raug nquahu kom siv cov khoom tiv thaiv tsim nyog, ua haujlwm nyob rau hauv ib thaj chaw muaj cua zoo, thiab ua raws cov lus qhia kev nyab xeeb rau kev khaws thiab pov tseg.
Zuag qhia tag nrho, 3-nitrobenzoic acid yog ib qho kev sib txuas lus tseem ceeb siv hauv ntau cov ntawv thov kev muaj kev lag luam vim tias nws feem ntau ua synthesiate hauv cov synthic synthesis.
