Isingeniso

I-5-methyl-2-acetylfran iyinhlanganisela yezinto eziphilayo.

 

I-compound inalezi zimpawu ezilandelayo:

Ukubukeka: uketshezi oluphuzi olungenambala noma olukhanyayo.

Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo, njenge-ethanol, i-methanol ne-methylene chloride.

Ukuminyana: cishe 1.08 g/cm3.

 

Ukusetshenziswa okubalulekile kwe-5-methyl-2-acetylfran kufaka:

I-Chemical synthesis: Njengengxenye ephakathi kokusabela kwe-organic synthesis, ingasetshenziswa ukuhlanganisa ezinye izinhlanganisela eziphilayo.

 

Izindlela zokulungiselela i-5-methyl-2-acetylfran zifaka:

Ilungiswa kusuka ku-5-methyl-2-hydroxyfuran nge-acylation.

Ilungiswa nge-acetylation ye-5-methylfuran nge-acetylating agent (isb, i-acetic anhydride) kanye ne-catalyst (isb, i-sulfuric acid).

 

Kuyacasula futhi kufanele kugwenywe ukuthintana nesikhumba namehlo.

Ukuhogela umoya noma ukukungenisa ngephutha kungase kubangele ukucasuka kwamaphaphu kanye nokungakhululeki kokugaya ukudla, futhi izingane nezilwane ezifuywayo kufanele zigcinwe kude.

Izinyathelo zokuphepha ezifanele, njengokugqoka izingubo zamehlo ezivikelayo namagilavu, kufanele zisetshenziswe ngesikhathi sokusebenza.

Lapho ugcina, kufanele ivalwe ngokuqinile futhi iqhelelane nemithombo yomlilo nama-oxidants.
