Chemical Properties:

1-Butanol yog ib hom cawv nrog plaub carbon atoms nyob rau hauv ib molecule. Nws cov mis molecular yog CH3CH2CH2CH2OH nrog peb isomers, uas yog iso-butanol, sec-butanol thiab tert-butanol. Nws yog xim tsis muaj kua nrog cawv tsw qab.
Nws muaj qhov kub ntawm qhov kub ntawm 117.7 ℃, qhov ceev (20 ℃) ​​yog 0.8109g / cm3, qhov chaw khov yog -89.0 ℃, flash point yog 36 ~ 38 ℃, qhov taw tes nws tus kheej yog 689F thiab qhov ntsuas tsis pom kev. ua (n20D) 1.3993. Ntawm 20 ℃, nws solubility hauv dej yog 7.7% (los ntawm qhov hnyav) thaum cov dej solubility hauv 1-butanol yog 20.1% (los ntawm qhov hnyav). Nws yog miscible nrog ethanol, ether thiab lwm yam organic solvents. Nws tuaj yeem siv los ua cov kuab tshuaj ntawm ntau yam xim thiab cov khoom siv raw rau kev tsim cov plasticizers, dibutyl phthalate. Nws tseem tuaj yeem siv rau kev tsim khoom ntawm butyl acrylate, butyl acetate, thiab ethylene glycol butyl ether thiab tseem siv tau los ua cov extract ntawm intermediates ntawm organic synthesis thiab biochemical tshuaj thiab kuj siv tau nyob rau hauv kev tsim cov surfactants. Nws cov chav tuaj yeem tsim cov khoom tawg nrog cov huab cua nrog qhov txwv tsis pub tawg yog 3.7% ~ 10.2% (qhov feem me me).

Daim ntawv thov:

1. feem ntau yog siv rau hauv kev tsim cov phthalic acid, aliphatic dibasic acid thiab n-butyl phosphate plasticizers, uas yog dav siv nyob rau hauv ntau yam yas thiab roj hmab khoom. Nws tseem yog cov khoom siv raw rau kev ua butyraldehyde, butyric acid, butylamine thiab butyl lactate hauv organic synthesis. Nws kuj yog siv los ua tus neeg ua kom lub cev qhuav dej, tiv thaiv emulsifier thiab extractant ntawm cov roj thiab roj, tshuaj (xws li tshuaj tua kab mob, tshuaj hormones thiab vitamins) thiab cov txuj lom, thiab ntxiv cov alkyd resin txheej. Nws kuj yog siv los ua cov kuab tshuaj rau cov organic dyes thiab luam ntawv inks, thiab ua tus neeg sawv cev dewaxing. Siv los ua cov kuab tshuaj los cais cov poov tshuaj perchlorate thiab sodium perchlorate, kuj tuaj yeem cais sodium chloride thiab lithium chloride. Siv los ntxuav sodium zinc uranyl acetate precipitate. Siv hauv kev txiav txim siab colorimetric los txiav txim siab arsenic acid los ntawm txoj kev molybdate. Kev txiav txim siab ntawm cov rog hauv nyuj cov mis nyuj. Nruab nrab rau saponification ntawm esters. Kev npaj cov tshuaj paraffin-embedded rau microanalysis. Siv los ua cov kuab tshuaj rau cov rog, waxes, resins, shellacs, pos hniav, thiab lwm yam. Co-solvent rau nitro spray xim, thiab lwm yam.

2. Chromatographic tsom xam cov qauv tshuaj. Siv rau kev txiav txim siab colorimetric ntawm arsenic acid, hnyav rau kev sib cais ntawm potassium, sodium, lithium thiab chlorate.
3. Ib qho hnyav hnyav, siv ntau ntau hauv kev tsim cov urea-formaldehyde resins, cellulose resins, alkyd resins thiab xim, thiab kuj yog ib qho tsis muaj zog diluent hauv cov nplaum. Nws tseem yog ib qho tseem ceeb tshuaj raw khoom siv nyob rau hauv zus tau tej cov plasticizer dibutyl phthalate, aliphatic dibasic acid ester thiab phosphate ester. Nws kuj yog siv los ua tus neeg ua kom lub cev qhuav dej, tiv thaiv emulsifier thiab extractant rau roj, txuj lom, tshuaj tua kab mob, tshuaj hormones, vitamins, thiab lwm yam, additive rau alkyd resin xim, co-solvent rau nitro spray xim, thiab lwm yam.
4. Tshuaj pleev ib ce hnyav. Nws yog tsuas yog siv los ua cov kuab tshuaj nyob rau hauv cov ntsia thawv polish thiab lwm yam tshuaj pleev ib ce kom phim nrog lub ntsiab hnyav xws li ethyl acetate, uas yuav pab kom yaj cov xim thiab tswj cov volatility thiab viscosity ntawm cov kuab tshuaj. Tus nqi ntxiv feem ntau yog li 10%.
5. Nws tuaj yeem siv los ua tus neeg sawv cev antifoaming rau ink blending hauv kev tshuaj ntsuam luam ntawv.
6. Siv rau hauv cov khoom ci, paj npleg, khoom qab zib.
