m-toluic acidwaa crystal cad ama huruud ah, ku dhowaad aan milmayn biyaha, wax yar ku milmay biyo karkaraya, milmay ethanol, ether. Iyo qaacidada molecular C8H8O2 iyo CAS nambar 99-04-7. Waxaa caadi ahaan loo isticmaalaa warshadaha kala duwan ujeedooyin kala duwan. Maqaalkan, waxaanu sahamin doonaa sifooyinka, isticmaalka, iyo milanka m-toluic acid.
Astaamaha m-toluic acid:
m-toluic acidwaa wax yar udgoon, crystalline cad oo adag oo leh barta dhalaalaysa 105-107 ° C. Waxay si yar ugu milmay biyaha, waxayna ku milmaysaa dareerayaasha organic sida alkohol, benzene, iyo ether. Qaab dhismeedka kiimikaad ee m-toluic acid waxaa ka mid ah giraanta benzene oo leh koox kaarboxyl -COOH oo ku dheggan giraanta booska meta. Qaabayntan qaabdhismeedku waxa ay siinaysaa m-toluic acid sifooyin iyo adeegsi kala duwan.
Isticmaalka m-toluic acid:
m-toluic acidwaa kiimiko dhexdhexaad ah oo muhiim ah oo loo isticmaalo warshado kala duwan, oo ay ku jiraan dawooyinka, balaastikada, iyo midabaynta. Waxaa inta badan loo isticmaalaa soo saarista metolachlor, oo ah doog doog ah oo la xushay oo loo isticmaalo in lagu xakameeyo haramaha ku jira galleyda iyo digirta. m-toluic acid waxay door muhiim ah ka ciyaartaa isku dhafka metolachlor, taas oo ku lug leh falcelinta m-toluic acid oo leh thionyl chloride si ay u sameyso dhexdhexaadin dheeraad ah oo laga baaraandegay si loo sameeyo badeecada ugu dambeysa.
Isticmaalka kale ee m-toluic acid waa soo saarista polymers sida polyamides iyo polyester resins. Polymers-yadan waxaa loo isticmaalaa soo saarista alaabooyin kala duwan sida dunta, balaastikada, iyo xabagta. m-toluic acid waa qayb muhiim ah oo ka mid ah isku dhafka polymers-kan, halkaas oo ay u shaqeyso sidii monomer ah oo isku xira molecules kale si ay u sameeyaan silsiladda polymer.
milanka m-toluic acid:
m-toluic acidayaa si yar ugu milmay biyaha, taas oo macnaheedu yahay in ay ku milmaan biyaha ilaa xad. milanka m-toluic acid ee biyaha waa ilaa 1.1 g/l heerkulka qolka. Milicsanaantan waxaa saameeya arrimo kala duwan sida heerkulka, pH, iyo joogitaanka dareeraha kale ee dareeraha.
Solubility xaddidan ee m-toluic acid ee biyaha waxaa sabab u ah joogitaanka kooxda karboksyl ee qaab-dhismeedkeeda. Kooxda carboxyl waa koox shaqaynaysa dabaysha oo la falgasha molecules biyaha iyada oo loo marayo isku xidhka hydrogen. Si kastaba ha ahaatee, giraanta benzene ee m-toluic acid waa nonpolar, taas oo ka dhigaysa inay celiso molecules biyaha. Sababo la xiriira guryahan iska soo horjeeda, m-toluic acid cas 99-04-7 ayaa ku milmay biyaha xaddidan.
Gabagabo:
m-toluic acid cas 99-04-7waa kiimiko dhexdhexaad ah oo muhiim ah oo leh codsiyo warshadeed oo kala duwan. m-toluic acid cas 99-04-7 waxaa loo isticmaalaa isku dhafka metolachlor, polyamides, iyo resins polyester. In kasta oo ay muhiim u tahay warshadahan, m-toluic acid waxay leedahay milmayn xaddidan oo biyaha ah. Hantidan waxaa sabab u ah dabeecadda iska hor imaadka ah ee kooxaha ka shaqeeya dabaysha iyo kuwa aan polar-ka ahayn. Si kastaba ha ahaatee, milanka hooseeya ee m-toluic acid ma saameynayso faa'iidada ay u leedahay warshadaha ay u adeegto.
