| I-Hazard Class | I-IRRITANT |
Isingeniso
I-methyl iyinhlanganisela ye-organic ene-molecular formula C7H8N2O2 kanye nesisindo samangqamuzana angu-148.15g/mol. Iwuketshezi olungenambala olunephunga elikhethekile.
Le nhlanganisela ivame ukusetshenziswa emkhakheni wezidakamizwa zokwenziwa, izibulala-zinambuzane kanye nodayi. Ingasetshenziswa njengesimaphakathi sokuhlanganiswa kwezinye izinhlanganisela eziphilayo, njenge: i-synthetic insecticide dimethicarb.
Indlela yokulungisa i-methyl ngokuvamile itholakala ngokusabela kwe-esterification. Indlela ethize iwukusabela i-5-methyl pyrazole-3-carboxylic acid nge-methanol, phambi kwe-catalyst efanelekile, ukuthola umkhiqizo owufunayo.
Mayelana nolwazi lokuphepha, i-methyl iwuketshezi oluvuthayo futhi kufanele igcinwe kude namalangabi avulekile kanye namazinga okushisa aphezulu. Ngesikhathi sokusetshenziswa nokugcinwa, ukunakekelwa kufanele kuthathwe ukuze ugweme ukuthintana nesikhumba, amehlo kanye nomgudu wokuphefumula. Ngesikhathi esifanayo, umsebenzi kufanele ugqoke izinto zokuzivikela ezifanele, njengamagilavu, izibuko kanye nemaski yokuzivikela. Uma udliwe noma uhogelwe, funa usizo lwezokwelapha ngokushesha.
