Intshayelelo

I-L-Histidine i-methyl ester dihydrochloride yi-chemical compound. Oku kulandelayo yinkcazo yeepropati zekhompawundi, ukusetyenziswa, iindlela zokulungiselela, kunye nolwazi lokhuseleko:

 

Umgangatho:

- Imbonakalo: Umgubo omhlophe wekristale.

- Ukunyibilika: Inyibilika emanzini nakwizinyibilikisi ezisekwe etywaleni, ezinganyibilikiyo kwizinyibilikisi ezingezizo ipolar.

 

Sebenzisa:

- L-Histidine methyl ester dihydrochloride isetyenziswa ngokuqhelekileyo njenge-catalyst kwi-organic synthesis. Idlala indima yecatalytic kwiintshukumo ezithile zeekhemikhali, ezifana ne-esterification kunye ne-alcohol condensation.

 

Indlela:

- L-Histidine Methyl Ester dihydrochloride idla ngokulungiswa ngokuphendula i-N-benzyl-L-histidine methyl ester kunye ne-hydrochloric acid phantsi kweemeko ezifanelekileyo.

- Le ndlela yokudibanisa ilula kwaye inokwenziwa elabhoratri.

 

Ulwazi ngoKhuseleko:

I-L-Histidine Methyl Ester Dihydrochloride ikhuselekile ngokubanzi ukuyiphatha, kodwa ngenxa yokuba iyikhemikhali, kufuneka kuthathwe la manyathelo okhuseleko alandelayo:

-Qhagamshelana: Gwema ukudibana ngokuthe ngqo kwesikhumba ukuphepha ukucaphuka.

Ukuphefumla: Kuphephe ukuphefumla uthuli okanye iigesi. Iimeko ezifanelekileyo zokungenisa umoya kufuneka zigcinwe xa kusingathwa le khompawundi.

- Ukucima umlilo: Xa kuthe kwakho umlilo, cima umlilo ngesixhobo esifanelekileyo sokucima umlilo.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
