m-toluic acidIngabe i-crystal emhlophe noma ephuzi, icishe ibe insoluble emanzini, incibilika kancane emanzini abilayo, incanel e-ethanol, ether. Kanye nefomula ye-molecular c8h8o2 ne-CAS Inombolo 99-04-7. Isetshenziswa kakhulu kwizimboni ezahlukahlukene ngezinhloso ezihlukile. Kulesi sihloko, sizohlola izakhiwo, sisebenzisa, kanye ne-solubility ye-m-toluic acid.
Izakhiwo ze-M-toluic acid:
m-toluic acidinamakha kancane, i-crystalline emhlophe eqinile enendawo yokuncibilika ye-105-107 ° C. Kuyancibilika emanzini, futhi kuyancibilika ezinhlamsweni eziphilayo ezinjengotshwala, uBenzene, no-Ether. Isakhiwo samakhemikhali se-M-Toluic Acid sifaka phakathi indandatho ye-benzene eneqembu le-carboxyl -Cooh elinamathiselwe kwindandatho endaweni ye-meta. Lokhu kulungiswa kwesakhiwo kunika i-M-toluic acid izakhiwo ezahlukahlukene nokusebenzisa.
Ukusetshenziswa kwe-M-toluic acid:
m-toluic acidIkhemikhali elibalulekile eliphakathi elisetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi amakhambi, amapulasitiki kanye nodayi. Isetshenziswa kakhulu ekukhiqizweni kwe-metolachlor, i-herbicide ekhethiwe esetshenziselwa ukulawula ukhula emndenini nasebhokweni. I-M-toluic acid idlala indima ebalulekile ekuhlanganiseni kwe-metolachlor, okubandakanya ukusabela kwe-m-toluic acid nge-thionolyl chloride ukwakha okuphakathi nendawo okusetshenzelwa phambili ukwakha umkhiqizo wokugcina.
Okunye ukusetshenziswa kwe-M-toluic acid kukhiqizwa ama-polymers afana nama-polyamides kanye nama-polyester resins. Lawa ma-polymers asetshenziswa ekwenziweni kwemikhiqizo ehlukahlukene efana nezindwangu, amapulasitiki, kanye nama-adhesives. I-M-toluic acid iyingxenye ebalulekile ekuhlanganiseni kwalawa ma-polymers, lapho isebenza khona njenge-molecule exhumanisa namanye ama-molecule ukuze wakhe i-polymer chain.
I-Solubity ye-M-toluic acid:
m-toluic acidinciphisa amanzi emanzini, okusho ukuthi kuncibilika emanzini kuye ngezinga elithile. I-solubity ye-m-toluic acid emanzini imayelana ne-1.1 g / l emazingeni okushisa asekamelweni. Lokhu kuSolubity kuthonywa yizinto ezahlukahlukene ezifana nokushisa, pH, kanye nokuba khona kwezinye izithako ezivela ku-solvent.
I-solubity elinganiselwe ye-M-toluic acid emanzini kungenxa yokuba khona kweqembu le-carboxyl esakhiweni salo. I-Carboxyl Group iyiqembu elisebenzayo elisebenzayo elisebenzisana nama-molecule amanzi nge-hydrogen bonding. Kodwa-ke, indandatho ye-benzene e-m-toluic acid ayilona i-nopolar, eyenza ukuthi iphinde icasule ama-molecule amanzi. Ngenxa yalezi zindawo ezingqubuzanayo, i-m-toluic acid cas 99-04-7 ine-soubity elilinganiselwe emanzini.
Isiphetho:
m-toluic acid cas 99-04-7Amakhemikhali abalulekile aphakathi anezicelo ezahlukahlukene zezimboni. I-M-toluic acid cas 99-04-7 isetshenziswa ekuhlanganiseni kwe-metolachlor, ama-polyamides, kanye nama-polyester resen. Naphezu kokubaluleka kwayo kulezi zimboni, i-m-toluic acid ine-soubhility elinganiselwe emanzini. Le mpahla ingenxa yohlobo oluphikisayo lwamaqembu alo asebenzayo namaqembu angenayo. Kodwa-ke, ukubulawa okuphansi kwe-M-toluic acid akukuthinti ukusiza kwayo ezimbonini ezisebenza kuzo.
