Nhanganyaya

Isoamyl doro, inozivikanwawo se isobutanol, ine makemikari formula C5H12O. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:

 

Hunhu:

1. Isoamyl doro imvura isina ruvara ine waini inokosha inonhuwira.

2. Iine nzvimbo yekubikira ye131-132 °C uye hukama hwepakati hwe 0.809g/mLat 25 °C (lit.).

3. Isoamyl alcohol inonyungudika mumvura uye yakawanda organic solvents.

 

Shandisa:

1. Isoamyl doro inowanzoshandiswa sechinhu chinogadziriswa uye ine zvakawanda zvakasiyana-siyana zvekushandisa mukuputira, inki, zvishongedzo uye kuchenesa.

2. Isoamyl alcohol inogonawo kushandiswa kugadzira mamwe macompounds akadai seethers, esters, and aldehydes and ketones.

 

Nzira:

1. Nzira yakajairika yekugadzirira isoamyl doro inowanikwa ne acidic alcohololysis reaction ye ethanol uye isobutylene.

2. Imwe nzira yekugadzirira inowanikwa nehydrogenation ye isobutylene.

 

Zvekuchengetedza

1. Isoamyl alcohol imvura inobvira inogona kukonzera moto kana yaiswa panzvimbo inobatidza moto.

2. Paunenge uchishandisa isoamyl doro, zvakakosha kuti urege kufema, kubata neganda kana kupinza mumuviri kudzivirira kukanganisa kuhutano.

3. Matanho akanaka ekufambisa mhepo anofanira kutorwa paunenge uchishandisa isoamyl doro kuti uve nechokwadi chekutenderera kwemhepo mukati.

4. Kana yadonha, isoamyl doro rinofanirwa kuparadzaniswa nekukurumidza, uye kudonha kunofanirwa kuraswa nemazvo kuti kusapindirana nezvimwe zvinhu.
