m-toluic asidhiikristaro chena kana yero, inenge isinganyungudike mumvura, inonyungudika zvishoma mumvura iri kufashaira, inonyungudika mu ethanol, ether. Uye iyo molecular formula C8H8O2 uye CAS nhamba 99-04-7. Inowanzoshandiswa mumaindasitiri akasiyana kune zvinangwa zvakasiyana. Muchikamu chino, tichaongorora zvivakwa, mashandisirwo, uye kunyungudika kwem-toluic acid.
Zvinhu zve m-toluic acid:
m-toluic asidhiinonhuwirira zvishoma, chena yekristaro yakasimba uye inonyungudika inosvika 105-107°C. Inonyungudika zvishoma mumvura, uye inonyungudika muorganic solvents sedoro, benzene, uye ether. Mushonga wemakemikari wem-toluic acid unosanganisira ring yebenzene ine carboxyl boka -COOH yakanamatira mhete panzvimbo yemeta. Iyi dhizaini yekumisikidza inopa m-toluic acid akasiyana zvivakwa uye mashandisiro.
Kushandiswa kwem-toluic acid:
m-toluic asidhiikemikari yakakosha yepakati inoshandiswa mumaindasitiri akasiyana siyana, kusanganisira emishonga, mapurasitiki, uye dhayi. Inonyanya kushandiswa mukugadzirwa kwemetolachlor, mushonga wesora wakasarudzika unoshandiswa kudzora sora muchibage nesoya. m-toluic acid inoita basa rakakosha mukuumbwa kwemetolachlor, iyo inosanganisira kuita kwem-toluic acid ine thionyl chloride kuumba yepakati iyo inogadziridzwa zvakare kugadzira chigadzirwa chekupedzisira.
Kumwe kushandiswa kwem-toluic acid kuri mukugadzirwa kwemapolymers semapolyamides nemapolyester resins. Aya mapolymer anoshandiswa mukugadzira zvigadzirwa zvakasiyana semachira, mapurasitiki, uye zvinonamira. m-toluic asidhi chinhu chakakosha mukuumbwa kwemapolymer aya, kwaanoita semonoma inobatana nemamwe mamorekuru kuumba polymer cheni.
Solubility ye m-toluic acid:
m-toluic asidhiinonyungudika zvishoma mumvura, zvinoreva kuti inonyungudika mumvura kusvika pamwero wakati. Kunyungudika kwem-toluic acid mumvura kunosvika 1.1 g/L patembiricha yekamuri. Kunyungudika uku kunokonzerwa nezvinhu zvakasiyana senge tembiricha, pH, uye kuvapo kwezvimwe zvinonyungudutsa musolvent.
Iyo shoma solubility yem-toluic acid mumvura inokonzerwa nekuvapo kweboka re carboxyl muchimiro chayo. Boka recarboxyl iboka rinoshanda repolar rinodyidzana nemamorekuru emvura kuburikidza nehydrogen bonding. Zvisinei, mhete yebenzene iri mum-toluic acid haisi polar, izvo zvinoita kuti idzinge mamorekuru emvura. Nekuda kwezvinhu izvi zvinopokana, m-toluic acid cas 99-04-7 ine mashoma solubility mumvura.
Mhedziso:
m-toluic asidhi cas 99-04-7ikemikari yakakosha yepakati ine akasiyana maindasitiri ekushandisa. m-toluic acid cas 99-04-7 inoshandiswa mukugadzira metolachlor, polyamides, uye polyester resins. Pasinei nekukosha kwayo mumaindasitiri aya, m-toluic acid ine mashoma solubility mumvura. Ichi chivakwa chinokonzerwa nekupokana kwechimiro chepolar uye nonpolar functional groups. Nekudaro, iyo yakaderera solubility ye-m-toluic acid haikanganisi kubatsira kwayo mumaindasitiri ayo anoshandira.
