2-Chloro-5-fluorobenzaldehyde (CAS# 84194-30-9)
Ngozi uye Kuchengeteka
| Risk Codes | R22 – Zvinokuvadza kana ikamedzwa R37/38 - Inogumbura kune yekufema system uye ganda. R41 - Njodzi yekukuvara kwakakomba kwemaziso |
| Tsanangudzo Yekuchengetedza | S26 – Kana wasangana nemaziso, sukurudza nekukurumidza nemvura yakawanda uye tsvaga mazano ekurapwa. S39 - Pfeka dziviriro yeziso / kumeso. |
| Hazard Kirasi | IRRITANT |
Nhanganyaya
-Kuonekwa: White crystal kana light yellow solid.
-Kunyungudika nzvimbo: anenge 40-42 ℃.
-Kubikira poindi: inenge 163-165 ℃.
-Density: inenge 1.435g/cm³.
-Solubility: Inonyungudika mune zvimwe zvakajairika organic solvents, senge ethanol, chloroform uye dichloromethane.
Shandisa:
Inonyanya kushandiswa kwemakemikari maitiro mune organic synthesis. Inogona kushandiswa senge yepakati ye fluorescent dhayi, seyakasvibirira mundima yemishonga, uye mumunda wekurima wekugadzira mishonga yezvipembenene.
Kugadzirira nzira:
inogona kugadzirwa neklorini, fluorinated benzaldehyde nzira. Iyo chaiyo nzira yekugadzirira ndeyotevera:
1. Pasi pemamiriro akakodzera, hydrofluoric acid inowedzerwa ku benzaldehyde kuti iite kuti iite fluorination reaction.
2. Mushure mekuita, hydrogen chloride inowedzerwa kune chlorinate iyo fluorinated product.
3. ita matanho akakodzera ekuchenesa kuti uwane phosphonium yakachena.
Zvekuchengetedza
- zvinhu zvinokuvadza, zvinogona kukonzera kutsamwa uye kukanganisa kumuviri womunhu. Pfeka magirovhosi ekudzivirira, magirazi uye midziyo yekudzivirira yekufema kana zvichidikanwa.
-Dzivisa kufema guruva rayo kana gasi, uye dzivisa kusangana neganda nemaziso.
-Panguva yekuchengetedza uye kushandiswa, maitiro ekuchengetedza makemikari anofanirwa kucherechedzwa, uye mamiriro ekufema akakodzera anofanira kuchengetedzwa.
-Kusangana netsaona kana kupinza, tsvaga kurapwa nekukurumidza uye upe data rakakodzera rekuchengetedza.
