Nhanganyaya
Phenylethyl isovalerate; Phenyl 3-methylbutylrate, kemikari formula ndeye C12H16O2, molecular uremu ndeye 192.25.
Zvakasikwa:
1. Kuonekwa: mvura isina ruvara, inonhuhwirira inonhuwira.
2. Solubility: soluble in alcohols, ethers uye yakawanda organic solvents, isinganyunguriki mumvura.
3. Melting Point:-45 ℃
4. Poindi yekubikira: 232-234 ℃
5. Density: 1.003g/cm3
6. Refractive index: 1.502-1.504

Shandisa:
Phenylethyl isovalerate;Phenethyl 3-methylbutylrate inowanzoshandiswa sechinhu muzvinonhuwira uye zvinonaka zvinopa zvigadzirwa kunhuhwirira kwakanaka kwemuchero, senge shuga yemichero, zvinwiwa zvemichero uye ice cream. Uye zvakare, inogona zvakare kushandiswa seyakagadzirwa zvinhu zvekuchenesa maajenti, zvinonyungudutsa uye mafuta ekuzora.
Kugadzirira nzira:
Phenylethyl isovalerate; Phenyl 3-methylbutanol inowanzogadzirirwa nekuita kweacetophenone uye isopropanol muhupo hwekugadzirisa. Iyo chaiyo nzira yekugadzirira ndeyotevera:
1. Sanganisa acetophenone uye isopropanol mu molar ratio.
2. Wedzera huwandu hwakakodzera hweasidhi catalyst (yakadai sesulfuric acid).
3. Kurudzira mhinduro yekugadzirisa pane imwe tembiricha yakaderera (kazhinji 0-10 ° C). Muzviitiko zvenguva dzose, nguva yekuita maawa akawanda kusvika kumakumi emaawa.
4. Mushure mokunge mhinduro yacho yapera, chigadzirwa chinonatswa kuburikidza nematanho ekugadzirisa, kupatsanurwa, kushambidza uye distillation.
Zvekuchengetedza
Phenylethyl isovalerate;Phenethyl 3-methylbutylrate inowanzoonekwa yakachengeteka pasi pemamiriro akajairika ekushandiswa. Zvisinei, imvura inopfuta, dzivisa kutarisana zvakananga nemoto wakazaruka kana kupisa kwakanyanya. Inofanira kuchengetwa munzvimbo inotonhorera, ine mhepo yakanaka. Paunenge uchishandiswa, pfeka zvinodzivirira zvakakodzera zvakadai segirovhosi nemagirazi ekudzivirira. Kana ukabata ganda rako kana maziso netsaona, sukurudza pakarepo nemvura yakawanda. Kana ukafemeswa kana ukapinzwa nekukanganisa, tsvaga kurapwa nekukurumidza.
