Nhanganyaya

N-butanol, inozivikanwawo sebutanol, inhengo yeorganic, imvura isina ruvara uye inonhuwirira doro. Iyi inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza yen-butanol:

 

Hunhu:

1. Zvimiro zvemuviri: Imvura isina ruvara.

2. Chemical properties: Inogona kunyungudutswa mumvura uye organic solvents, uye ine mwero polar compound. Inogona kuve oxidized kune butyraldehyde uye butyric acid, kana inogona kupera mvura kuti iite butene.

 

Shandisa:

1. Kushandiswa kwemaindasitiri: Chinhu chakakosha chekunyungudutsa uye chine huwandu hwakawanda hwemashandisirwo muindasitiri yemakemikari senge coatings, ingi, uye detergents.

2. Kushandiswa murabhoritari: Inogona kushandiswa sechinhu chinonyungudutsa kupeta helical protein, uye inowanzoshandiswa mukuedza kwebiochemical kugadzirisa maitiro.

 

Nzira:

1. Butylene hydrogenation: Mushure mekuita hydrogenation, butene inobatwa nehaidhirojeni muhupo hwechigadziriso (senge nickel catalyst) kuwana n-butanol.

2. Dehydration reaction: butanol inogadziriswa neakasimba acids (yakadai seconcentrated sulfuric acid) kuti iite butene kuburikidza nekushaya mvura, uye ipapo butene inonzi hydrogenated kuti iwane n-butanol.

 

Zvekuchengetedza

1. Imvura inopfuta, dzivisa kusangana nemoto, uye chengetedza kure nemirazvo yakazaruka uye nzvimbo dzekushisa kwepamusoro.

3. Iine humwe huturu, dzivisa kubata zvakananga neganda nemaziso, uye dzivisa kupinza mhute yayo.

4. Paunenge uchichengeta, inofanira kuchengetwa munzvimbo yakavharwa, kure neoxidants uye zvitubu zvemoto, uye kuchengetwa pakupisa kwekamuri.
