Isingeniso

I-Isobutyl mercaptan iyinhlanganisela ye-organosulfur. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-isobutyl mercaptan:

 

1. Imvelo:

I-Isobutylmercaptan iwuketshezi olungenambala olunephunga elimnandi. Inokuminyana okuphezulu kanye nomfutho womhwamuko ogcwele phansi. Iyancibilika emanzini nasezincibilikisini eziningi eziphilayo ezifana notshwala, ama-ether, nezinyibilikisi zeketone.

 

2. Ukusetshenziswa:

I-Isobutyl mercaptan isetshenziswa kabanzi ku-organic synthesis kanye nezimboni. Ingasetshenziswa njenge-ejenti ye-vulcanizing, i-suspension stabilizer, i-antioxidant, ne-solvent. I-Isobutyl mercaptan ingasetshenziswa futhi ekulungiseni izinhlobonhlobo zezinhlanganisela ku-organic synthesis, njengama-esters, ama-ester sulfonated, nama-ether.

 

3. Indlela:

Kunezindlela ezimbili eziyinhloko zokulungiswa kwe-isobutyl mercaptan. Enye ilungiswa ukusabela kwe-isobutylene nge-hydrogen sulfide, futhi izimo zokusabela ngokuvamile zenziwa ngaphansi kwengcindezi ephezulu. Enye ikhiqizwa ukusabela kwe-isobutyraldehyde nge-hydrogen sulfide, bese umkhiqizo uyancishiswa noma ukhishwe i-deoxid ukuthola i-isobutylmercaptan.

 

4. Ulwazi Lokuphepha:

I-Isobutylmercaptan iyacasula futhi iyagqwala, futhi ukuthintana nesikhumba namehlo kungase kubangele ukucasuka nokusha. Uma usebenzisa i-isobutyl mercaptan, okokusebenza okuvikelayo okufanelekile njengezingubo zamehlo ezivikelayo, amagilavu, nezimpahla zokuzivikela kufanele zigqokwe. Uma uphatha i-isobutyl mercaptan, kufanele igcinwe kude nemithombo yokuthungela kanye nama-oxidants ukugwema ukudala umlilo nokuqhuma. Uma i-isobutyl mercaptan ihogelwa noma idliwe, kufanele ufune usizo lwezokwelapha ngokushesha futhi unikeze udokotela wakho ulwazi oluningiliziwe mayelana namakhemikhali.

    • Bhala umyalezo wakho lapha futhi usithumelele wona
