Nhanganyaya
1-Bromo-3,3,3-trifluoroacetone. Inotevera sumo yezvivakwa, mashandisirwo, nzira dzekugadzirira uye ruzivo rwekuchengetedza kwekomputa iyi:
Hunhu:
1-Bromo-3,3,3-trifluoroacetone imvura isina ruvara ine kunhuhwirira kwakakosha pakupisa kwekamuri uye kumanikidza. Inonyungudika mudoro, ether, uye mamwe organic solvents, uye isinganyungudika mumvura. Komboni ine high vapor pressure uye volatility.
Shandisa:
1-Bromo-3,3,3-trifluoroacetone ine huwandu hwakawanda hwekushandisa muindasitiri yemakemikari. Imwe yemashandisirwo makuru ndeyekugadzira yepakati yefluoroacetone. Inoshandiswawo secatalyst ye organic synthesis uye se surfactant.
Nzira:
Iyo synthesis ye1-bromo-3,3,3-trifluoroacetone inowanzoitwa nenzira yebromohydrofluoric acid. Acetone inobatwa ne hydrofluoric acid mune reactor kuwana bromoacetone. Zvadaro, sodium bromide yakawedzerwa kumusanganiswa wekuita, uye iyo bromination reaction yakaitwa kuti iwane 1-bromo-3,3,3-trifluoroacetone. Icho chinangwa chigadzirwa chinowanikwa ne distillation uye kucheneswa.
Zvekuchengetedza
1-Bromo-3,3,3-trifluoroacetone inogumbura uye inogona kuva nemigumisiro yakaipa pameso, ganda, uye kufema. Paunenge uchishandisa, matanho akakodzera ekudzivirira akadai seyekudzivirira maziso, magirovhosi, uye zvekufema anofanira kutorwa. Inofanirwa kushandiswa munzvimbo inofefetera zvakanaka uye kudzivirira kusangana nezvinhu zvakaita semaoxidants akasimba.
