Nhanganyaya

3-mercapto-2-butanone, inozivikanwawo se2-butanone-3-mercaptoketone kana MTK, inhengo yemubatanidzwa. Iyi inotevera sumo yezvivakwa zvayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:

 

Hunhu:

-Kuonekwa: Mvura isina ruvara kana chena kristaro

- Solubility: Soluble mu ethanol, ether uye chloroform, inonyungudika zvishoma mumvura

 

Shandisa:

- Kemikari reagents: inowanzo shandiswa se sulfhydrylation reagents mune organic synthesis ye synthesis ye sulfhydryl makomisheni.

- Kushandiswa kwekutengesa: 3-mercapto-2-butanone, se sulfhydryl reagent, inowanzoshandiswa mukugadzirira kwerabha additives, rubber accelerators, glyphosate (a herbicide), surfactants, nezvimwewo.

 

Nzira:

Nzira yakajairika yekugadzirira kwe3-mercapto-2-butanone ndeyekuita kwehexane imwe ine hydrogen sulfide. Nhanho chaiyo ndeyekuita hexanone nehydrogen sulfide kuburikidza nesilica gel column kuti uwane 3-mercapto-2-butanone.

 

Zvekuchengetedza

- 3-mercapto-2-butanone imvura inopfuta uye inofanirwa kudzivirirwa kubva mumurazvo wakavhurika kana kupisa kwakanyanya.

- Pfeka matanho ekudzivirira akakodzera semagirazi ekudzivirira, magirovhosi uye zvipfeko zvakakodzera zvisingaputika panguva yekushandiswa.

- Nzwisisa uye uteedzere akakodzera maitiro ekushanda uye chengetedzo nhungamiro yekushandisa usati washandisa.

- Dzivisa kusangana nezvinhu zvakaita seoxidants, maasidhi akasimba, mabhesi akasimba, uye maoxidants akasimba kudzivirira maitiro ane njodzi.

- Kana wasangana netsaona, sukurudza nekukurumidza nemvura yakawanda uye tsvaga kurapwa nekukasika.

 

Izvo zvakakosha kushandisa uye kubata iyi komputa zvakachengeteka uye zvinoenderana nemaprotocol uye nhungamiro.
