Ntsiab Cai
- Acetone (CAS 67-64-1)yog ib qho hnyav uas sib tov tag nrho nrog dej thiab evaporates sai.
- Feem ntau siv: ntsia thawv polish remover, tsheb thiab rooj tog lacquers, textile degumming thiab degreasing, thiab yas ntau lawm.
- Cov qib sib txawv feem ntau yog qib impurity: technical, general reagent (GRG), BP thiab qib kev lag luam.
- Acetone yog flammable; kom deb ntawm qhov hluav taws kub thiab ua haujlwm nrog qhov cua.
1. Dab tsi Acetone siv rau
Acetone yog ib qho ceev ceev -evaporating hnyav uas sib tov zoo nrog dej, ua rau nws zoo haum rau ntau tsev neeg thiab kev tsim khoom siv: ntsia thawv polish tshem tawm, tsheb lossis rooj tog lacquer, degumming thiab degreasing agents rau textiles, thiab yas ntau lawm. Industrially nws kuj yog ib qho hnyav rau cov xim, inks thiab adhesives, ib tug tu tus neeg sawv cev nyob rau hauv cov kab ntau lawm, thiab ib tug intermediate nyob rau hauv lub chemistry ntawm methyl methacrylate thiab bisphenol -A-raws li polymers. Nyob rau hauv lub laboratory nws yog ib qho kev tshuaj ntsuam xyuas thiab ntxuav cov kuab tshuaj.
2. Puas muaj qhov sib txawv ntawm Acetone?
Yog lawm. Acetone muaj nyob rau hauv ntau qib, qhov sib txawv tseem ceeb yog theem ntawm impurities tam sim no. Qee qib kev kawm, uas zoo txaus los ua cov kuab tshuaj tab sis tsis yog rau kev sib txuas lossis kev tshuaj ntsuam xyuas, tuaj yeem nqa cov khoom tsis zoo (xws li dej, aldehydes thiab condensation los ntawm - khoom), thiab cov no tuaj yeem ua lub luag haujlwm rau cov ntxhiab tsw zoo dua.

Qhov tseeb purity qhov tseem ceeb yog txhais los ntawm cov lus qhia ntawm txhua qib; paub meej nrog tus neeg muag khoom daim ntawv pov thawj ntawm kev txheeb xyuas. Rau kev tshawb fawb -qib cov ntsiab lus siv, ACS reagent acetone feem ntau teev nyob rau ntau dua lossis sib npaug rau 99.5% purity.
4. Cov ntawv ceeb toom kev nyab xeeb
Acetone yog cov kua ua kua heev. Tshaj tawm kaw- khob cov ntsiab lus sib txawv me ntsis los ntawm qhov chaw thiab cov qauv ntsuas, feem ntau poob ntawm li -18℃thiab -20 degree, nrog rau qhov kub thiab txias ntawm ib ncig ntawm 465℃. Khaws nws deb ntawm tshav kub, sparks thiab qhib nplaim taws, xyuas kom cov khoom siv hauv av kom zoo kom tsis txhob muaj hluav taws xob zoo li qub thaum hloov mus, siv qhov cua kom txaus lossis lub fume hood, tsis txhob sib cuag ntawm daim tawv nqaij thiab qhov muag, thiab ua raws li cov ntaub ntawv kev nyab xeeb (SDS) ntawm cov khoom tshwj xeeb.
Cov lus nug nquag
Q1. CAS tus naj npawb ntawm acetone yog dab tsi?
CAS 67-64-1 Nr.
Q2. Kuv yuav tsum xaiv qib acetone twg?
Technical lossis industrial qib rau kev tu thiab siv hnyav; GRG lossis BP qib rau kev kuaj lossis tshuaj siv tshuaj.
Q3. Puas yog acetone muaj kev nyab xeeb los daws?
Nws yog flammable thiab volatile; kov nrog lub qhov cua, kom deb ntawm qhov hluav taws kub, thiab ua raws li SDS.
Q4. Puas yog acetone sib xyaw nrog dej?
Yog - acetone yog miscible tag nrho nrog dej nyob rau hauv tag nrho cov proportions.
