Isingeniso

I-Dibutyl sulfide (eyaziwa nangokuthi i-dibutyl sulfide) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-dibutyl sulfide:

 

Ikhwalithi:

- Ukubukeka: I-BTH ngokuvamile iwuketshezi olungenambala olunephunga elingavamile le-thioether.

- Ukunyibilika: I-BH iyancibilika kuzincibilikisi zemvelo njenge-ethanol, i-ether ne-benzene, kodwa ayincibiliki emanzini.

- Ukuzinza: Ngaphansi kwezimo ezijwayelekile, i-BTH izinzile uma kuqhathaniswa, kodwa ukuvutha okuzenzakalelayo noma ukuqhuma kungase kwenzeke emazingeni okushisa aphezulu, ukucindezela, noma lapho kubhekene nomoya-mpilo.

 

Sebenzisa:

- Njengento encibilikisayo: I-Dibutyl sulfide ivame ukusetshenziswa njengesixazululi, ikakhulukazi ekuphenduleni kwe-organic synthesis.

- Ukulungiswa kwamanye ama-compounds: I-BTHL ingasetshenziswa njengendawo ephakathi ekuhlanganiseni ezinye izinhlanganisela eziphilayo.

- I-Catalyst ye-organic synthesis: I-Dibutyl sulfide ingasetshenziswa futhi njenge-catalyst ye-organic synthesis reactions.

 

Indlela:

- Indlela evamile yokulungiselela: I-Dibutyl sulfide ingalungiswa ngokusabela kwe-1,4-dibutanol ne-hydrogen sulfide.

- Ukulungiselela Okuthuthukile: Elabhorethri, ingabuye ilungiswe ngokusabela kukaGrignard noma i-thionyl chloride synthesis.

 

Ulwazi Lokuphepha:

- Imithelela emzimbeni womuntu: I-BTH ingangena emzimbeni ngokuhogela umoya nangokuthinta isikhumba, okungase kubangele ukucasuka kwamehlo, ukucasuka kokuphefumula, ukungezwani komzimba nesikhumba, kanye nokucindezeleka kwesimiso sezinzwa esimaphakathi. Ukuxhumana okuqondile kufanele kugwenywe futhi kuqinisekiswe ukungena komoya okwanele.

- Izingozi zomlilo neziqhumane: I-BTH ingase ithungele ngokuzenzakalelayo noma iqhume emazingeni okushisa aphezulu, izingcindezi, noma lapho ichayeke kumoya-mpilo. Kufanele kuqashelwe ukugwema ukuthungela nokukhipha i-electrostatic, futhi ugcine esitsheni esingangeni moya.

- Ubuthi: I-BTH inobuthi ezintweni zasemanzini futhi kufanele igwenywe ukuze idedelwe endaweni ezungezile.
