m-toluic acidyog dawb los yog daj siv lead ua, yuav luag insoluble nyob rau hauv dej, me ntsis soluble nyob rau hauv boiling dej, soluble nyob rau hauv ethanol, ether.Thiab cov mis mos molecular C8H8O2 thiab CAS naj npawb 99-04-7.Nws yog feem ntau siv nyob rau hauv ntau yam kev lag luam rau ntau lub hom phiaj.Hauv tsab xov xwm no, peb yuav tshawb txog cov khoom, kev siv, thiab solubility ntawm m-toluic acid.
Cov yam ntxwv ntawm m-toluic acid:
m-toluic acidyog ib tug me ntsis tsw, dawb crystalline khoom nrog ib tug melting point ntawm 105-107 ° C.Nws yog soluble me ntsis hauv dej, thiab soluble hauv cov kuab tshuaj organic xws li cawv, benzene, thiab ether.Cov qauv tshuaj ntawm m-toluic acid suav nrog lub nplhaib benzene nrog pawg carboxyl -COOH txuas rau lub nplhaib ntawm txoj haujlwm meta.Cov qauv kev teeb tsa no muab m-toluic acid sib txawv thiab siv.
Kev siv ntawm m-toluic acid:
m-toluic acidyog ib qho tseem ceeb nruab nrab cov tshuaj siv nyob rau hauv ntau yam industries, xws li tshuaj, yas, thiab dyes.Nws yog tsuas yog siv nyob rau hauv zus tau tej cov metolachlor, ib tug xaiv herbicide siv los tswj cov nroj tsuag nyob rau hauv pob kws thiab soybeans.m-toluic acid plays lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm metolachlor, uas koom nrog cov tshuaj tiv thaiv ntawm m-toluic acid nrog thionyl chloride los ua ib qho nruab nrab uas tau ua tiav ntxiv los tsim cov khoom kawg.
Lwm qhov kev siv ntawm m-toluic acid yog nyob rau hauv zus tau tej cov polymers zoo li polyamides thiab polyester resins.Cov polymers no yog siv los tsim ntau yam khoom xws li textiles, plastics, thiab adhesives.m-toluic acid yog ib qho tseem ceeb nyob rau hauv synthesis ntawm cov polymers, uas nws ua raws li ib tug monomer uas txuas nrog rau lwm cov molecules los tsim cov polymer saw.
Solubility ntawm m-toluic acid:
m-toluic acidyog sparingly soluble nyob rau hauv dej, uas txhais tau hais tias nws dissolves nyob rau hauv dej mus rau ib tug txwv.Solubility ntawm m-toluic acid nyob rau hauv dej yog hais txog 1.1 g / L ntawm chav tsev kub.Qhov solubility no cuam tshuam los ntawm ntau yam xws li kub, pH, thiab muaj lwm cov kuab tshuaj hauv cov kuab tshuaj.
Qhov txwv tsis pub solubility ntawm m-toluic acid hauv dej yog vim muaj cov carboxyl pawg hauv nws cov qauv.Cov pab pawg carboxyl yog pawg ua haujlwm polar uas cuam tshuam nrog cov dej molecules los ntawm kev sib txuas ntawm hydrogen.Txawm li cas los xij, lub nplhaib benzene hauv m-toluic acid yog nonpolar, uas ua rau nws tawm tsam cov dej molecules.Vim cov khoom tsis sib haum no, m-toluic acid cas 99-04-7 muaj kev txwv tsis pub solubility hauv dej.
Xaus:
m-toluic acid CAS 99-04-7yog ib qho tseem ceeb ntawm cov tshuaj nruab nrab nrog ntau yam kev siv hauv kev lag luam.m-toluic acid cas 99-04-7 yog siv nyob rau hauv synthesis ntawm metolachlor, polyamides, thiab polyester resins.Txawm hais tias nws qhov tseem ceeb hauv cov kev lag luam no, m-toluic acid tau txwv tsis pub solubility hauv dej.Cov cuab yeej no yog vim qhov tsis sib haum xeeb ntawm nws cov polar thiab nonpolar functional pawg.Txawm li cas los xij, qhov qis solubility ntawm m-toluic acid tsis cuam tshuam rau nws cov txiaj ntsig hauv kev lag luam uas nws ua haujlwm.
