Isingeniso

2-Methylbutyric acid. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-methylbutyric acid:

 

Ikhwalithi:

Ukubukeka: I-2-methylbutyric acid iwuketshezi olungenambala noma ikristalu.

Ukuminyana: cishe. 0.92 g/cm³.

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

 

Sebenzisa:

Ingasetshenziswa futhi njenge-solvent yama-resin, ama-plasticizers amapulasitiki, nezincibilikisi zokumboza.

I-2-Methylbutyric acid ingasetshenziswa futhi ekulungiseleleni ama-metal rust inhibitors kanye nezincibilikizeli zikapende.

 

Indlela:

Izindlela zokulungiselela ze-2-methylbutyric acid ikakhulukazi zimi kanje:

Ilungiswa ukusabela kwe-oxidation ye-ethanol.

Ilungiselelwe ukusabela kwe-oxidation ye-2-methacryrolen.

 

Ulwazi Lokuphepha:

I-2-Methylbutyric acid iyacasula futhi ingabangela ukucasuka kanye ne-erythema lapho uthintana nesikhumba, futhi ukuthintana ngqo nesikhumba kufanele kugwenywe.

Ukuhogela umoya we-2-methylbutyric acid kungabangela ukucasuka komphimbo, ukucasuka kokuphefumula, nokukhwehlela, futhi kufanele kuqashelwe ukungena komoya kanye nokuvikelwa komuntu siqu.

Ngesikhathi sokusetshenziswa, ukuthintana nama-oxidants aqinile nezinto ezivuthayo kufanele kugwenywe ukuvimbela ukusabela okuyingozi.

Lapho ugcina futhi uphatha, ukudlidliza okukhulu namazinga okushisa aphezulu kufanele kugwenywe.

 

  • Okwedlule:
