Isingeniso

I-Methoxybenzyl utshwala. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-methoxybenzyl alcohol:

 

Ikhwalithi:

Ukubukeka: I-Methoxybenzyl alcohol iwuketshezi olungenambala olunganukwa.

Ukunyibilika: I-Methoxybenzyl alcohol ayincibiliki kancane emanzini, kodwa iyancibilika kuzincibilikisi eziningi eziphilayo.

Ukuzinza: I-Methoxybenzyl alcohol iyazinza uma kuqhathaniswa nezinga lokushisa legumbi, kodwa ingase isabele lapho ihlangana nama-oxidants aqinile.

 

Sebenzisa:

I-Methoxybenzyl alcohol ingasetshenziswa njenge-solvent, i-reaction intermediate kanye ne-catalyst stabilizer ku-organic synthesis.

Ingasetshenziswa futhi njengesithako kumakha nama-flavour, inikeze imikhiqizo iphunga elikhethekile.

 

Indlela:

I-Methoxybenzyl alcohol ingalungiswa ngokufakwa kwe-methanol kanye ne-benzyl alcohol. Lokhu kusabela kudinga i-catalyst kanye nezimo ezifanele zokusabela.

Ingase futhi isabele nge-oxidant nge-benzyl alcohol ukukhiqiza utshwala be-methoxybenzyl.

I-Benzyl alcohol + i-oxidant → utshwala be-methoxybenzyl

 

Ulwazi Lokuphepha:

I-Methoxybenzyl alcohol iyisincibilikisi esiphilayo futhi kufanele isetshenziswe ngokuhambisana nezinqubo zokuphepha zaselabhorethri yamakhemikhali evamile.

Kungase kubangele ukucasuka kwamehlo nesikhumba, futhi izibuko zokuzivikela namagilavu ​​kufanele kugqokwe ngesikhathi sokuphatha.

Uma uhogelwe noma ungenwe ngephutha, funa usizo lwezokwelapha ngokushesha futhi unikeze iphakheji noma ilebula kudokotela wakho ukuze ayisebenzise.

 

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
