Selelekela

Isobutyl mercaptan ke motsoako oa organosulfur. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea isobutyl mercaptan:

1. Tlhaho:

Isobutylmercaptan ke mokelikeli o se nang 'mala o monko o monate. E na le boima bo phahameng le khatello e tlase ea mouoane. E qhibiliha ka metsing le lihlapolli tse ngata tsa tlhaho tse kang joala, ethers, le ketone solvents.

2. Tšebeliso:

Isobutyl mercaptan e sebelisoa haholo ho organic synthesis le indastering. E ka sebelisoa e le moemeli oa vulcanizing, suspension stabilizer, antioxidant, le solvent. Isobutyl mercaptan e ka boela ea sebelisoa ha ho etsoa metsoako e fapaneng ea metsoako ea lintho tse phelang, tse kang esters, sulfonated esters, le ethers.

3. Mokhoa:

Ho na le mekhoa e 'meli ea mantlha ea ho lokisa isobutyl mercaptan. E 'ngoe e lokiselitsoe ke karabelo ea isobutylene e nang le hydrogen sulfide,' me maemo a karabelo hangata a etsoa tlas'a khatello e phahameng. E 'ngoe e hlahisoa ke karabelo ea isobutyraldehyde e nang le hydrogen sulfide, ebe sehlahisoa se fokotsehile kapa se fokotsehile ho fumana isobutylmercaptan.

4. Litaba tsa Polokeho:

Isobutylmercaptan e ea teneha ebile e senya, 'me ho kopana le letlalo le mahlo ho ka baka ho teneha le ho chesa. Ha u sebelisa isobutyl mercaptan, lisebelisoa tse loketseng tsa ts'ireletso tse kang liaparo tsa mahlo tse sireletsang, liatlana le liaparo tse sireletsang li lokela ho apesoa. Ha o sebetsana le isobutyl mercaptan, e lokela ho bolokoa hole le mehloli ea mollo le li-oxidants ho qoba ho baka mollo le ho phatloha. Haeba isobutyl mercaptan e hema kapa e kenngoa, u lokela ho batla ngaka hang-hang 'me u fe ngaka ea hau lintlha tse qaqileng mabapi le lik'hemik'hale.
