Igama lemveliso:n-butanol

Imo yemolekyuli:C4H10O

Inombolo yeCAS:71-36-3

Imveliso yesakhiwo semolekyuli:

Iipropati zeMichiza:

I-n-Butanol inokutsha kakhulu, ayinambala kwaye inevumba elibonakalayo elinamandla, ibilisa kwi-117 ° C kwaye inyibilika ku -80 ° C. Le propati yotywala iququzelela ukuveliswa kweekhemikhali ezithile ezifunekayo ukupholisa yonke inkqubo. I-n-Butanol inetyhefu ngakumbi kunanoma yimuphi umlingani wayo, njenge-sec-butanol, i-tert-butanol okanye i-isobutanol.

Isicelo:

I-1-Butanol iyona nto ibaluleke kakhulu kumashishini kwaye ifundwe kakhulu. I-1-Butanol lulwelo olungenambala kunye nevumba elinxilisayo elinamandla, elithambileyo. Isetyenziswa kwizinto eziphuma kwikhemikhali nanjengento yokunyibilikisa iipeyinti, iiwax, iibrake fluid, kunye nezicoci.
I-Butanol yincasa yokutya evumelekileyo ebhalwe "kwimigangatho yezempilo yezongezo zokutya" yaseTshayina. Isetyenziswa kakhulu ekulungiseleleni incasa yokutya yeebhanana, ibhotolo, itshizi kunye newhiskey. Kwi-candy, inani lokusetyenziswa kufuneka libe yi-34mg / kg; ukutya okubhakiweyo, kufuneka kube yi-32mg / kg; kwiziphuzo ezithambileyo, kufuneka kube yi-12mg / kg; kwiziselo ezibandayo, kufuneka ibe yi-7.0mg/kg; ngenxa yekhilimu, kufuneka ibe yi-4.0mg / kg; kuba utywala, kufuneka 1.0mg/kg.
Isetyenziswa ikakhulu ukwenza i-n-butyl plasticizers ye-phthalic acid, i-aliphatic dicarboxylic acid kunye ne-phosphoric acid ezisetyenziswa ngokubanzi kwiintlobo ezahlukeneyo zeplastiki kunye neemveliso zerabha. Inokusetyenziswa kwakhona njengento ekrwada yokuvelisa i-butyraldehyde, i-butyric acid, i-butyl-amine kunye ne-butyl lactate kwintsimi ye-organic synthesis. Isenokusetyenziswa njenge-agent yokukhutshwa kweoli, amachiza (afana ne-antibiotics, ihomoni kunye neevithamini) kunye neziqholo kunye nezongezo zepeyinti yealkyd. Ingasetyenziswa njengesinyibilikisi sedayi eziphilayo kunye ne-inki yokuprinta kunye ne-agent de-waxing.
