2-Methyl-5-nitrobenzenesulfonamide (CAS# 6269-91-6)

Selelekela

Ke motsoako oa manyolo o nang le foromo C7H8N2O4S. Ke phofo e tšoeu ea kristale e nang le acidity e fokolang. E latelang ke tlhaloso ea thepa, tšebeliso, tokiso le tlhaiso-leseling ea polokeho ea komporo:

Tlhaho:

-Ponahalo: phofo e tšoeu ea kristale

- Boima ba molek'hule: 216.21g/mol

- ntlha ea ho qhibiliha: 168-170 ℃

-Solubility: E qhibiliha hanyane ka metsing, ho bonolo ho qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le acetone.

-acid le alkaline: acid e fokolang

Sebelisa:

-e sebelisoa haholo ho organic synthesis joalo ka reagent ea bohlokoa le ea mahareng.

-E ka sebelisoa ho lokisa lik'hemik'hale tse kang lithethefatsi, dae le thepa ea polymer.

Mokhoa oa ho itokisa:

E ka etsoa ka mehato e latelang: br>1. Ntlha ea pele, tlas'a maemo a nepahetseng a karabelo, methyl bromide le p-nitrobenzene sulfonamide li etsoa ho theha methyl ester.

2. Joale, methyl ester e etsoa ka tharollo ea alkaline ho fumana letsoai.

Lintlha tsa Tšireletseho:

-e lokela ho bolokoa sebakeng se omeletseng, se nang le moea o motle, le ho qoba khanya ea letsatsi.

-Nakong ea ts'ebetso, qoba ho kopana le letlalo le mahlo. Haeba e pepesehile, e hlatsoe hang-hang ka metsi a mangata 'me u batle thuso ea bongaka.

-Apara lisebelisoa tse nepahetseng tsa ho itšireletsa tse kang liatlana, likhalase tsa tšireletso le liaparo tsa tšireletso ha u tšoara motsoako.

-U se ke ua kopanya motsoako ona le li-oxidants tse matla le li-acids tse matla, hobane li ka baka liketso tse kotsi.

-Pele o sebelisa kapa o sebetsana le motsoako, litaelo tsa tekheniki tsa polokeho tse fanoeng ke mofani oa thepa li lokela ho baloa ka hloko.
