ethyl 5-methoxy-1-benzofuran-2-carboxylate (CAS# 50551-56-9)

Intshayelelo

I-Ethyl yi-organic compound. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:

Indalo:

-Imbonakalo: ulwelo olungenambala

-Ifomula yemolekyuli: C13H12O4

-Ubunzima beMolekyuli: 232.23

-indawo yokunyibilika: 37-39 ℃

-indawo ebilayo: 344-346 ℃

-Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo ezifana nekloroform, i-ethanol kunye ne-dichloromethane, i-soluble kancinane emanzini.

Sebenzisa:

- I-ethyl l yinto esetyenziswa ngokuqhelekileyo ye-organic synthesis intermediate engasetyenziselwa ukudibanisa iziyobisi, iihomoni kunye neemveliso zendalo.

-Inokusetyenziswa kwakhona njengento yokubhekisela kwinkalo yophando lwamachiza kunye nokuhlanganiswa kweziyobisi.

Indlela yokulungiselela:

I-ethyl idla ngokudityaniswa ngala manyathelo alandelayo:

1. Okokuqala, i-methoxybenzofuran ifakwe endaweni ye-bromoacetic acid ukufumana i-5-methoxybenzofuran -2-acetic acid.

2. Emva koko, i-5-methoxybenzofuran-2-acetic acid iphendulwa nge-thionyl chloride (SOCl2) ukuyiguqula ibe yi-acid chloride.

3. Ekugqibeleni, i-acid chloride iphendulwa kunye ne-ethanol ukuvelisa i-ethyl phenyl.

Ulwazi ngoKhuseleko:

- i-ethyl yikhemikhali efuna ukugcinwa ngokucophelela kunye nokuphathwa.

-Iyacaphukisa kwaye kufuneka igweme ukudibanisa nolusu kunye namehlo. Kwimeko yoqhagamshelwano ngengozi, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango.

-Ukusetyenziswa, kufuneka kugcinwe iimeko ezilungileyo zokungenisa umoya, ukuphepha ukuphefumla igesi kunye nomphunga.
