Intshayelelo

2-Methylbutyric acid. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2-methylbutyric acid:

 

Umgangatho:

Imbonakalo: I-2-methylbutyric acid iyilwelo olungenambala okanye ikristale.

Ubuninzi: malunga. 0.92 g/cm³.

Ukunyibilika: I-2-methylbutyric acid inyibilika ngokuyinxenye emanzini.

 

Sebenzisa:

Isenokusetyenziswa njengento yokunyibilikisa iintlaka, iiplastiki zeplastiki, nezinyibilikisi zokwaleka.

I-2-Methylbutyric acid ingasetyenziselwa ukulungiswa kwe-rust inhibitors yensimbi kunye ne-solvents yepeyinti.

 

Indlela:

Iindlela zokulungiselela i-2-methylbutyric acid ikakhulu zilandelayo:

Ilungiswa yi-oxidation reaction ye-ethanol.

Ilungiselelwe yi-oxidation reaction ye-2-methacryrolen.

 

Ulwazi ngoKhuseleko:

I-2-Methylbutyric acid iyacaphukisa kwaye inokubangela ukucaphuka kunye ne-erythema xa idibene nesikhumba, kwaye ukudibanisa ngokuthe ngqo kwesikhumba kufuneka kugwenywe.

Ukuphefumla umphunga we-2-methylbutyric acid kunokubangela ukucaphuka komqala, ukucaphuka ukuphefumla, kunye nokukhohlela, kwaye ingqwalasela kufuneka ihlawulwe ekungeneni komoya kunye nokhuseleko lomntu.

Ngexesha lokusetyenziswa, ukudibana nee-oxidants ezinamandla kunye nezinto ezinokutsha kufuneka zigwenywe ukukhusela ukuphendula okuyingozi.

Xa ugcina kunye nokuphatha, ukungcangcazela okukhulu kunye nokushisa okuphezulu kufuneka kugwenywe.

 

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