Mawu Oyamba
1-(2,4-Dichlorophenyl) -1-propanone, mankhwala formula C9H8Cl2O, ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: 1- (2,4-Dichlorophenyl) -1-propanone ndi madzi opanda mtundu mpaka kuwala achikasu.
-Kachulukidwe: Kachulukidwe ake ndi pafupifupi 1.29 g/mL.
-Kusungunuka: Kusungunuka kwa 1-(2,4-Dichlorophenyl) -1-propanone pafupifupi pakati pa -5 ° C ndi -3 ° C.
-Powira: Kuwira kwake kuli pakati pa 169°C ndi 171°C.
-Kusungunuka: 1- (2,4-Dichlorophenyl) -1-propanone imasungunuka muzitsulo zamadzimadzi monga ethanol, acetone ndi dimethylformamide.
Gwiritsani ntchito:
-Kuphatikizika kwamankhwala: 1- (2,4-Dichlorophenyl) -1-propanone imagwiritsidwa ntchito kwambiri popanga organic synthesis ndipo imagwiritsidwa ntchito ngati reagent mu kafukufuku ndi labotale.
- Mankhwala kaphatikizidwe: Amagwiritsidwanso ntchito ngati zopangira za kaphatikizidwe ka mankhwala ena ndi intermediates mankhwala.
Njira Yokonzekera:
1-(2,4-Dichlorophenyl) -1-propanone ikhoza kukonzedwa ndi njira iyi:
-Pamaso pa alkali, 2,4-dichlorobenzaldehyde imakhudzidwa ndi acetone kupanga 1-(2,4-Dichlorophenyl) -1-propanone.
-Sodium hydride ndi 2,4-dichlorobenzaldehyde angagwiritsidwe ntchito hydrogenation mu acetone kukonzekera 1-(2,4-Dichlorophenyl) -1-propanone.
Zambiri Zachitetezo:
- 1-(2,4-Dichlorophenyl) -1-propanone ndi mankhwala ndipo ayenera kusungidwa bwino komanso motsatira njira zoyenera zogwirira ntchito zotetezeka.
-Ndi chinthu chomwe chimasokonekera ndipo chimayenera kusungidwa kutali ndi moto komanso kutentha kwambiri kuti pasakhale moto komanso kuphulika.
-Zida zodzitetezera ngati zida zoyenera zotetezera kupuma, zovala zoteteza mankhwala ndi magolovesi ziyenera kuvala panthawi yomwe zikugwiritsidwa ntchito kuti zipewe kukhudzana ndi kupuma.
-Ndikofunikira kukhala ndi mpweya wabwino pakagwiritsidwe ntchito popewa kudzikundikira kwa mpweya woipa.
-Ngati wakoweredwa kapena kukhudza khungu ndi maso, tsukani mwachangu ndi madzi ndikupempha thandizo lachipatala.
