Intshayelelo

I-1,2-Epibutane i-organic compound. Lulwelo olungenambala kunye nevumba elibi kwiqondo lobushushu begumbi. Oku kulandelayo sisingeniso kwiipropati zayo eziphambili, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

 

Iimpawu: Lulwelo olunokutsha olunokwenza umxube oqhumayo neoksijini. Ikwalusu olunamandla olucaphukisayo kunye nokucaphukisa amehlo.

 

Sebenzisa:

I-1,2-Butyloxide isetyenziswa ngokubanzi kwi-organic synthesis, amayeza, i-pesticides kunye neengubo. Yinto ebalulekileyo ephakathi kwaye idla ngokusetyenziswa kwi-organic synthesis ukulungiselela ezinye iikhompawundi, ezifana ne-alcohols, ii-ketones, i-ethers, njl njl.

 

Indlela:

I-1,2-Epibutane inokulungiswa ngokusabela kwe-octanol kunye ne-hydrogen peroxide. Indlela ekhethekileyo yokulungisa i-octanol kunye ne-hydrogen peroxide phambi kwe-catalyst efanelekileyo yokuvelisa i-1,2-epoxybutane.

 

Ulwazi ngoKhuseleko:

I-1,2-Epibutane yinto enobungozi enobungozi obunobungozi obufana nokucaphuka kunye ne-teratogenicity. Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa nolusu kunye nokuphefumla imiphunga yayo ngexesha lokusetyenziswa, kunye nezixhobo ezifanelekileyo zokukhusela ezifana neiglavu, izibuko, kunye nokukhuselwa kokuphefumula kufuneka kunikezelwe ukuba kuyimfuneko. Ngexesha lokugcinwa kunye nokuphatha, kufuneka kuthathelwe ingqalelo ukukhusela ukucima kunye nombane ongatshintshiyo. Kuphephe ukuxubana nee-oxidants ezinamandla kunye neeasidi ukuphepha ukuphendula okuyingozi. Xa kuchithwa inkunkuma, imigaqo nemimiselo yendawo kufuneka ilandelwe.
