i-ethyl 5-methoxy-1-benzofuran-2-carboxylate (CAS# 50551-56-9)
Isingeniso
I-Ethyl iyinhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: uketshezi olungenambala
-Ifomula ye-molecular: C13H12O4
Isisindo se-Molecular: 232.23
-indawo yokuncibilika: 37-39 ℃
-iphuzu abilayo: 344-346 ℃
-I-Solubility: Incibilika kuzincibilikisi eziphilayo njenge-chloroform, i-ethanol ne-dichloromethane, inyibilika kancane emanzini.
Sebenzisa:
- i-ethyl l iyinhlangano evame ukusetshenziswa kakhulu ye-organic synthesis engasetshenziswa ukuhlanganisa izidakamizwa, amahomoni nemikhiqizo yemvelo.
-Ingasetshenziswa futhi njengento eyinkomba emkhakheni wocwaningo lwezemithi kanye nokuhlanganiswa kwezidakamizwa.
Indlela Yokulungiselela:
I-ethyl ivamise ukwenziwa ngezinyathelo ezilandelayo:
1. Okokuqala, i-methoxybenzofuran ishintshwa nge-bromoacetic acid ukuze ithole i-5-methoxybenzofuran -2-acetic acid.
2. Bese, i-5-methoxybenzofuran-2-acetic acid iphendulwa nge-thionyl chloride (SOCl2) ukuyiguqula ibe yi-asidi chloride.
3. Ekugcineni, i-acid chloride isabela ne-ethanol ukuze ikhiqize i-ethyl phenyl.
Ulwazi Lokuphepha:
- i-ethyl l iyikhemikhali edinga ukugcinwa nokuphathwa ngokucophelela.
-Iyacasula futhi kufanele igweme ukuthintana nesikhumba namehlo. Uma kwenzeka ukuthintana ngephutha, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
-Isetshenziswa, kufanele igcine izimo ezinhle zokungenisa umoya, igweme ukuhogela igesi nomhwamuko.
