Intshayelelo

Dibromomethane. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-dibromomethane:

 

Umgangatho:

Inevumba elibi kwiqondo lobushushu begumbi kwaye ayinyibiliki emanzini, kodwa iyanyibilika kwizinyibilikisi ezininzi eziqhelekileyo eziphilayo.

I-Dibromomethyl yinto ezinzileyo yekhemikhali engaboli okanye ingene kwiikhemikhali ngokulula.

 

Sebenzisa:

I-Dibromomethane isoloko isetyenziswa njenge-solvent ye-organic synthesis reactions, ukunyibilika okanye ukukhupha i-lipids, i-resins kunye nezinye izinto eziphilayo.

I-Dibromomethane iphinda isetyenziswe njengento ekrwada yokulungiswa kwamanye ama-organic compounds, kwaye inezicelo kwezinye iinkqubo zoshishino.

 

Indlela:

I-Dibromomethane idla ngokulungiswa ngokusabela imethane ngebromine.

Phantsi kweemeko zokusabela, ibromine iyakwazi ukubuyisela iathom enye okanye ngaphezulu kwe-hydrogen kwi-methane ukwenza i-dibromomethane.

 

Ulwazi ngoKhuseleko:

I-Dibromomethane inetyhefu kwaye inokufunxwa ngokuphefumla, ukudibana kwesikhumba, okanye ukungeniswa. Ukuvezwa kwexesha elide kunokuba neziphumo ezibi kwimpilo.

Izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglavu, izikhuselo zobuso kufuneka zinxitywe xa zisetyenziswa.

Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa nemithombo yokutshisa xa ubamba kwaye ugcina i-dibromomethane, njengoko inokutsha.

I-Dibromomethane kufuneka igcinwe kude nemithombo yokushisa kunye nokushisa okuphezulu kwindawo epholileyo, epholileyo.

Xa usebenzisa, ukugcina okanye ukuphatha i-dibromomethane, iinkqubo zokusebenza ezikhuselekileyo kufuneka zilandelwe ngokungqongqo ukuqinisekisa ukhuseleko lomntu. Kwimeko yeengozi, amanyathelo afanelekileyo kaxakeka kufuneka athathwe.
