3-Methylisonicotinic acid (CAS# 4021-12-9)
| Izimpawu Eziyingozi | Xi - Irritant |
| Amakhodi Engozi | 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. |
| I-Hazard Class | I-IRRITANT |
Isingeniso
I-Acid iyinhlanganisela yemvelo enefomula yamakhemikhali C7H7NO2. Kuyikristalu eqinile engenambala, encibilika emanzini nasezincibilikisini eziphilayo.
I-Acid inezinhlobonhlobo zokusetshenziswa. Ingasetshenziswa njengendawo ephakathi ku-organic synthesis yokulungiselela ezinye izinhlanganisela. Ingase futhi isebenze njenge-ligand yezakhiwo ze-organometallic futhi ibambe iqhaza ekuphenduleni kwe-catalytic. Ngaphezu kwalokho, ingasetshenziswa futhi ekuhlanganiseni kwemithi ethile.
Ziningi izindlela zokulungiselela i-ICT. Enye indlela evamile ukuhlanganiswa ngokwelashwa kanye ne-oxidation ye-toluene. Ngokuqondile, i-toluene iqala ukusabela nge-acetaldehyde phambi kwe-ejenti ye-oxidizing ukukhiqiza i-3-methyl-4-picolinic acid ester, esuke ingaphansi kwe-acid hydrolysis ukuze kutholwe umkhiqizo ohlosiwe.
Ukuphepha kwe-asidi kuphezulu, kodwa ezinye izindaba zokuphepha zisadinga ukunakwa. Gqoka izinto zokuzivikela ezifanele njengezibuko namagilavu ngesikhathi sokusebenza. Gwema ukuhogela uthuli negesi okuwumphumela futhi ugweme ukuthintana nesikhumba. Ngesikhathi sokugcinwa nokuthutha, kufanele kuqashelwe izinyathelo zokuvikela umswakama, ukuvikela umlilo kanye nezinyathelo zokuvikela ukuqhuma. Uma ungenwa ngephutha noma uthintwa, funa iseluleko sezokwelapha ngokushesha futhi ulethe ishidi lokuphepha lalo mkhiqizo esibhedlela.
