Nhanganyaya

Dibromomethane. Iyi inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza dibromomethane:

 

Hunhu:

Iine hwema hunonhuwa pakupisa kwekamuri uye hainyungudike mumvura, asi inonyungudika mune zvakawanda zvakajairika organic solvents.

Dibromomethyl ikemikari yakagadzikana chinhu chisingaori kana kuita kemikari maitiro nyore.

 

Shandisa:

Dibromomethane inowanzoshandiswa sechinhu chinonyungudutsa cheorganic synthesis reactions, kunyungudika kana kubvisa lipids, resins uye zvimwe organic zvinhu.

Dibromomethane inoshandiswawo seyakagadzirwa kugadzirwa kwemamwe organic komisheni, uye ine maapplication mune mamwe maindasitiri maitiro.

 

Nzira:

Dibromomethane inowanzogadzirirwa nekuita methane ine bromine.

Pasi pemamiriro ekuita, bromine inokwanisa kutsiva imwe kana akawanda maatomu ehydrogen mumethane kuita dibromomethane.

 

Zvekuchengetedza

Dibromomethane ine chepfu uye inogona kutorwa nekufemerwa, kubata ganda, kana kupinza. Kuratidzwa kwenguva refu kunogona kuva nemigumisiro yakaipa yehutano.

Midziyo yekuzvidzivirira yakafanira semagirovhosi, magirovhosi, nenhoo yekumeso inofanirwa kupfekwa kana ichishandiswa.

Kuchengetedza kunofanirwa kutorwa kuti usabatane nezvinobatidza moto paunenge uchibata nekuchengetedza dibromomethane, sezvo ichibvira moto.

Dibromomethane inofanira kuchengetwa kure nenzvimbo dzinopisa uye tembiricha yakakwirira munzvimbo inotonhorera, ine mhepo yakanaka.

Paunenge uchishandisa, kuchengetedza kana kubata dibromomethane, nzira dzakachengeteka dzekushanda dzinofanira kuteverwa zvakanyanya kuti uve nechokwadi chekuchengetedzwa kwemunhu. Muchiitiko chetsaona, matanho akakodzera ekukurumidzira anofanira kutorwa.
