Isingeniso
I-2,4-Dimethyl-5-acetylthiazole iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwale nhlanganisela:
Ikhwalithi:
- Ukubukeka: I-2,4-Dimethyl-5-acetylthiazole iyi-crystalline ephuzi ekhanyayo noma impushana eqinile.
- Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo njenge-ethanol, i-ether ne-acetone, futhi inyibilika kancane emanzini.
Sebenzisa:
- Izibulala-zinambuzane: i-2,4-dimethyl-5-acetylthiazole isibulala-zinambuzane esibanzi esisetshenziswa ukulawula izinambuzane ezitshalwayo njengenundu le-leaf roller kanye ne-cabbage worm.
Indlela:
- I-2,4-Dimethyl-5-acetylthiazole ngokuvamile ilungiswa ngokuphendula i-2,4-dimethylthiazole nge-acylating agent efana ne-acetyl chloride. Ukusabela kwenziwa ku-solvent efanelekile, ifudunyezwe futhi inyakaze isikhathi esithile, bese ihlanzwa nge-crystallization noma ngokuhlunga ngokumunca.
Ulwazi Lokuphepha:
- Gqoka izinto zokuzivikela ezifanele ezifana namagilavu zelebhu nezingilazi zokuzivikela ngesikhathi sokusebenza kwezimboni.
- Gwema ukuthintana kwesikhumba kanye nokuhogela uthuli, intuthu, noma amagesi aphuma enkomponi.
- Lapho ugcina, gcina esitsheni esingangeni moya, kude nomlilo nama-oxidants.
- Ngesikhathi sokusetshenziswa, kuyadingeka ukulandela izinqubo ezifanele zokusebenza zokuphepha futhi uthathe izinyathelo zosizo lokuqala ezifanele ngokushesha uma kwenzeka ingozi. Esimeni sokuhogela ngephutha noma ukumunca ngephutha, funa usizo lwezempilo ngokushesha.
