Intshayelelo

I-isoamyl alcohol, eyaziwa ngokuba yi-isobutanol, inefomula yeekhemikhali C5H12O. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye neenkcukacha zokhuseleko:

Umgangatho:

1. I-isoamyl utywala ngulwelo olungenambala kunye nevumba elikhethekileyo lewayini.

2. Inendawo yokubilisa ye-131-132 °C kunye nokuxinana kwe-0.809g/mLat 25 °C (lit.).

3. Utywala be-isoamyl bunyibilika emanzini kunye nezona zinyibilikisiweyo zininzi.

Sebenzisa:

1. I-isoamyl yotywala isetyenziswa rhoqo njenge-solvent kwaye inoluhlu olubanzi lwezicelo kwiingubo, ii-inki, i-adhesives kunye ne-agent agents zokucoca.

2. Utywala be-isoamyl bunokusetyenziselwa ukudibanisa ezinye iikhompawundi ezinjengeethers, esters, kunye nealdehydes neeketones.

Indlela:

1. Indlela eqhelekileyo yokulungiselela i-isoamyl yotywala ifunyenwe nge-acidic alcohololysis reaction ye-ethanol kunye ne-isobutylene.

2. Enye indlela yokulungiselela ifunyenwe nge-hydrogenation ye-isobutylene.

Ulwazi ngoKhuseleko:

1. I-isoamyl utywala lulwelo olunokutsha olunokubangela umlilo xa luvezwe kumthombo wokutshisa.

2. Xa usebenzisa i-isoamyl yotywala, kuyimfuneko ukuphepha ukuphefumla, ukudibanisa nolusu okanye ukungena emzimbeni ukukhusela umonakalo kwimpilo.

3. Amanyathelo okungena komoya afanelekileyo kufuneka athathwe xa usebenzisa i-isoamyl alcohol ukuqinisekisa ukujikeleza komoya ngaphakathi.

4. Kwimeko yokuvuza, i-isoamyl alcohol kufuneka ibekwe yodwa ngokukhawuleza, kwaye ukuvuza kufuneka kulahlwe ngokufanelekileyo ukuphepha ukusabela kwezinye izinto.
