2 4-Dichlorobenzoyl chloride (CAS# 89-75-8)

Mawu Oyamba

Ubwino:

2,4-Dichlorobenzoyl chloride ndi madzi achikasu otuwa komanso onunkhira. Imakhala yosakhazikika pa kutentha kwa chipinda ndipo imasungunuka mosavuta ndi kuwonongeka, choncho iyenera kusungidwa pansi pa mpweya wa inert. Imakhudzidwa ndi ma hydrocarbon, ma amine onunkhira, ndi mowa kuti apange ma amide ndi esters ofanana.

Gwiritsani ntchito:

2,4-Dichlorobenzoyl chloride ndi yofunika kwambiri pakati pa kaphatikizidwe ka organic ndipo imakhala ndi ntchito zambiri zomwe zimachitika pakupanga organic. Itha kugwiritsidwa ntchito pokonza zotumphukira zosiyanasiyana za benzoyl chloride ndi mankhwala ena achilengedwe.

Njira:

2,4-Dichlorobenzoyl chloride ikhoza kupezedwa ndi chlorination wa p-nitrobenzoic acid kapena p-aminobenzoic acid. Njira yeniyeni ndi yochitira p-nitrobenzoic acid kapena p-aminobenzoic acid ndi thionyl chloride kuti apeze mankhwala apakatikati, ndiyeno mankhwala apakatikati amathiridwanso chloride kuti pamapeto pake apeze 2,4-dichlorobenzoyl chloride.

Zambiri Zachitetezo:

2,4-Dichlorobenzoyl chloride ndi organic pawiri yomwe imakwiyitsa komanso yowononga. Kusamala kuyenera kuchitidwa pakugwiritsa ntchito ndikugwira, kupewa kukhudzana ndi khungu, maso, ndi kupuma. Zida zodzitetezera zoyenera, monga magolovesi a labu, magalasi, ndi zovala zodzitchinjiriza, ziyenera kuvalidwa mkati mwa njirayi. Kukhudzana ndi zinthu zoyaka ndi ma oxidizing kuyenera kupewedwa kuteteza moto kapena kuphulika. Ikasungidwa ndi kunyamulidwa, iyenera kusindikizidwa ndikusungidwa kutali ndi moto ndi magwero a kutentha.
