Selelekela

Asiti ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C6H4BrO2S.

 

Tlhaho:

-Ponahalo: asiti e bosoeu ho isa ho bosehla bo tiileng.

-Solubility: E qhibiliha ka chloroform, acetone le chlorinated methane.

- Sebaka sa ho qhibiliha: hoo e ka bang likhato tse 116-118 tsa Celsius.

 

Sebelisa:

-must acid e atisa ho sebelisoa e le ntho ea bohlokoa lipakeng tsa organic synthesis.

-E ka sebelisoa ho etsa metsoako ea lintho tse phelang tse nang le mehaho ea selikalikoe sa thiophene.

 

Mokhoa oa ho itokisa: Ho na le mekhoa e mengata ea maiketsetso ea

- anacid. E 'ngoe ea mekhoa e sebelisoang hangata ke ho sebelisa asiti ea bromoacetic joalo ka lisebelisoa tse tala, ho sebetsana le thiophene tlasa maemo a alkaline ho hlahisa 3-bromothiophene, ebe e etsa karabelo ea carboxylic tlasa maemo a asiti.

 

Lintlha tsa Tšireletseho:

- acid e ka 'na ea halefisa mahlo, letlalo le tsamaiso ea ho hema.

-Nakong ea tšebeliso, tlhokomelo e lokela ho nkoa ho qoba ho hema lerōle kapa ho kopana le letlalo le mahlo.

-Apara lisebelisoa tse nepahetseng tsa ts'ireletso tse kang liatlana tsa lab, likhalase le lithebe tsa sefahleho pele u sebetsa.

-Ha u kopana le letlalo kapa mahlo, hlatsoa hang-hang ka metsi a mangata 'me u batle ngaka. Ho tla fanoa ka mehato e loketseng ea thuso ea pele ha ho hlokahala.
