Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi I-R22 – Iyingozi uma igwinywe
R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba.
R41 – Ingozi yokulimala okubi emehlweni
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.

Isingeniso

I-2-Methylthio-4-pyrimidinone iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: I-2-Methylthio-4-pyrimidinone iqinile yamakristalu angenambala noma ama-crystalline powders amhlophe.

- Ukunyibilika: Inokuncibilika okuphansi emanzini kodwa ukuncibilika okungcono kuzincibilikisi zemvelo njenge-ethanol ne-dimethyl sulfoxide.

- Ukusabela kwamakhemikhali: I-2-methylthio-4-pyrimidinone ingasabela nezinye izinhlanganisela ngokusebenzisa ukusabela kwamakhemikhali njenge-sulfonation, substitution, ne-cycloaddition.

 

Sebenzisa:

- I-Pesticide: I-2-methylthio-4-pyrimidinone iyi-insecticide ebalulekile kanye ne-herbicide ephakathi, esetshenziswa kabanzi emkhakheni wezolimo.

- Odayi be-Fluorescent: Angasetshenziswa futhi njengodayi be-fluorescent namalebula ama-reagents, anamandla okuthwebula izithombe nokutholwa ocwaningweni lwe-biomedical.

 

Indlela:

- I-2-Methylthio-4-pyrimidinone ingalungiswa ngokusabela kwe-2-methylthio-4-aminoimidazole nama-ketones ngaphansi kwezimo ze-acidic.

 

Ulwazi Lokuphepha:

- I-2-Methylthio-4-pyrimidinone iyinhlanganisela yezinto eziphilayo ezinobuthi obuthile. Izinyathelo ezifanele zokuzivikela, njengamagilavu, izibuko, nezingubo zokuzivikela, kufanele zithathwe lapho kusetshenziswa noma kuthintwa.

- Ukuthinta isikhumba noma ukuhogela uthuli lwaso kungase kubangele ukungezwani komzimba noma ukucasuka, futhi ukuchayeka isikhathi eside noma ukuhogela kakhulu kufanele kugwenywe.

- Ngesikhathi sokugcina nokuphatha, kufanele kuqashelwe ukugwema ukuthintana nama-oxidants, ama-acids aqinile, nezinye izinto ukugwema ukusabela okuyingozi.

- Lapho kulahlwa imfucuza, kufanele ilahlwe ngokuhambisana nemithethonqubo efanele ukuze kugwenywe ukungcoliswa kwemvelo.
