2 4-Dichlorophenylacetone (CAS# 37885-41-9)
| Izimpawu Eziyingozi | Xi - Irritant |
| Amakhodi Engozi | 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. |
Isingeniso
I-1-(2,4-Dichlorophenyl) -1-propanone, ifomula yamakhemikhali i-C9H8Cl2O, inhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: 1-(2,4-Dichlorophenyl) -1-propanone uketshezi oluphuzi olukhanyayo olungenambala.
-Ukuminyana: Ukuminyana kwayo kucishe kube ngu-1.29 g/mL.
-Indawo Encibilikayo: Iphuzu lokuncibilika lika-1-(2,4-Dichlorophenyl)-1-propanone cishe liphakathi kuka -5°C no -3°C.
-Iphuzu elibilayo: Iphuzu layo lokubila liphakathi kuka-169°C no-171°C.
-I-Solubility: I-1-(2,4-Dichlorophenyl) -1-propanone iyancibilika kuma-organic solvents njenge-ethanol, i-acetone ne-dimethylformamide.
Sebenzisa:
-I-Chemical synthesis: I-1- (2,4-Dichlorophenyl) -1-propanone isetshenziswa kabanzi ekuhlanganiseni kwezinto eziphilayo futhi ivame ukusetshenziswa njenge-reagent ocwaningweni naselabhorethri.
-Ukuhlanganiswa kwezidakamizwa: Ibuye isetshenziswe njengempahla eluhlaza yokuhlanganiswa kwezidakamizwa ezithile kanye nezidakamizwa.
Indlela Yokulungiselela:
I-1-(2,4-Dichlorophenyl) -1-propanone ingalungiswa ngale ndlela elandelayo:
-Ebukhoneni be-alkali, i-2,4-dichlorobenzaldehyde isabela nge-acetone ukukhiqiza i-1-(2,4-Dichlorophenyl) -1-propanone.
-I-sodium hydride ne-2,4-dichlorobenzaldehyde ingasetshenziselwa i-hydrogenation ku-acetone ukulungiselela i-1-(2,4-Dichlorophenyl) -1-propanone.
Ulwazi Lokuphepha:
- I-1-(2,4-Dichlorophenyl)-1-propanone iyikhemikhali futhi kufanele igcinwe ngendlela efanele futhi ngokuhambisana nezinqubo ezifanele zokusebenza eziphephile.
-Kuyinhlanganisela yemvelo eguquguqukayo futhi kufanele igcinwe kude namalangabi avulekile namazinga okushisa aphezulu ukugwema imililo nokuqhuma.
-Izinto zokuzivikela ezifana nemishini efanele yokuvikela ukuphefumula, izingubo zokuvikela amakhemikhali kanye namagilavu kufanele kugqokwe ngesikhathi sokusetshenziswa ukuvimbela ukuthintana nokuhogela.
-Kuyadingeka ukugcina izimo ezinhle zokungenisa umoya ngesikhathi sokusetshenziswa ukugwema ukuqoqwa kwamagesi ayingozi.
-Uma uhogeliwe noma uthinta isikhumba namehlo, geza ngokushesha ngamanzi futhi ufune usizo lwezokwelapha.
