Tshuaj Tshuaj Muaj Zog:

1-butanol yog hom dej cawv nrog plaub carbon atoms muaj nyob rau ib molecule. Nws cov mis molecular yog CH3ch2ch2oh nrog peb Isomers, uas yog Iso-Butanol, Sec-Butanol thiab Tert-Butanol. Nws yog cov kua tsis muaj kob uas muaj ntxhiab tsw.
Nws muaj qhov cub npau npau yog 117.7 ℃, qhov ntom (20 ℃) ​​yog 0.8109g / nyem, lub ntsej muag txias Ua (N20D) 1.3993. Ntawm 20 ℃, nws solubility hauv dej yog 7.7% (los ntawm qhov hnyav) thaum dej solubility hauv 1-butanol yog 20.1% (los ntawm qhov hnyav). Nws yog tus ua txhaum cai nrog Ethanol, Etaws thiab lwm yam ntawm cov kuab tshuaj organic. Nws tuaj yeem siv los ua cov kuab tshuaj ntawm ntau cov xim pleev xim rau ntau yam xim thiab cov khoom siv raw rau tsim cov tshuab yas, dib dibutyl phthalate. Nws kuj tseem siv tau rau kev tsim cov butyl acrylate, butyl acetate, thiab antylene glycole synmedia thiab tseem siv tau hauv kev tsim cov surfactants. Nws chav tuaj yeem ua cov sib xyaw ua ke nrog cov cua tawg nrog 3.7% ~ 10.2% (Ntim feem).

Daim Ntawv Thov:

1. Siv cov khoom lag luam phthalic, aliphatic dibasic acid thiab n-butyl phosphate yasizer, uas tau siv dav hauv ntau cov plastics thiab cov khoom lag luam roj hmab. Nws tseem yog cov khoom siv raw rau ua butyraldehyde, Butyric acid, butylamine thiab butyl lactate hauv cov organic synthesis. Nws tseem siv raws li lub cev qhuav dej, tiv thaiv cov roj thiab roj, xws li cov tshuaj tiv thaiv kab mob (xws li cov vitamins) thiab cov txuj lom, thiab cov txuj ci alkyd resin txheej. Nws kuj tseem siv los ua cov kuab tshuaj rau cov organic dyes thiab luam ntawv inks, thiab raws li tus neeg sawv cev Dewaxing. Siv los ua cov huab cua cais cov poov tshuaj perchlorate thiab sodium perchlorate, kuj tuaj yeem sib cais sodium chloride thiab lithium chloride. Siv los ntxuav sodium zinc uranyl acetate nag lossis daus. Siv hauv kev txiav txim siab Colorimetric txiav txim siab los txiav txim siab arsenic acid los ntawm txoj kev molybdate. Kev txiav txim siab ntawm cov rog hauv nyuj mis. Nruab nrab rau saponification ntawm esters. Kev npaj ntawm paraffin-embedded tshuaj rau microanalysis. Siv los ua cov kuab tshuaj rau cov rog, ua haujlwm, cov txiaj ntsig, shellacs, pos hniav, pos hniav rau nitro tshuaj tsuag xim, thiab lwm yam.

2. Chromatographic tsom xam cov qauv tshuaj. Siv rau kev txiav txim siab Colorimetric txiav txim siab ntawm arsenic acid, hnyav rau kev sib cais ntawm cov poov tshuaj, sodium, lithium thiab chlorate.
3. Ib qho tseem ceeb hnyav, siv hauv cov khoom loj hauv kev tsim cov khoom siv urea-formatdehyde, alkydue resins, alkyde, thiab kuj tseem muaj kev ua tsis muaj zog hauv cov nplaum. Nws tseem yog ib qho tseem ceeb cov khoom siv tshuaj uas muaj peev xwm siv tau ntawm cov yas yas ua kom zoo nkauj Nws tseem siv raws li lub cev qhuav dej, tiv thaiv cov roj, cov tshuaj tiv thaiv, cov tshuaj ntsuab, thiab lwm yam rau nitro tshuaj txau xim, thiab lwm yam.
4. Tshuaj pleev ib ce hnyav. Nws yog tsuas yog siv raws li co co-cam nyob rau hauv ntsia hlau polish thiab lwm cov tshuaj pleev ib ce kom pom cov xim thiab tswj cov volatility thiab viscosity ntawm cov kuab tshuaj. Qhov nyiaj ntxiv feem ntau yog li 10%.
5. Nws tuaj yeem siv ua Antifoaming tus neeg sawv cev rau number casing hauv tshuaj ntsuam luam ntawv.
6. Siv rau hauv cov khoom ci, paj npleg, khoom qab zib.
