o-Xylene (CAS 95-47-6) tau txais kev txiav txim los ntawm cov neeg yuav khoom ntawm peb tus lej ua ntej nws puas tau tawm ntawm qhov chaw thau khoom: purity, ntom, thiab boiling point.TIANJIN GNEE BIOTECH CO., LTD.muab cov lus teb ua ke hauv qab no rau pawg neeg yuav khoom thiab cov neeg ua haujlwm hauv chaw kuaj mob uas yuav tsum tau kuaj xyuas daim ntawv tso cai lossis COA tiv thaiv tus lej tiag, tsis yog daim ntawv lo xwb.
Purity ntawm o-Xylene
Lub purity ntawm o-Xylene ntawm lub lag luam kev lag luam khiav nyob qhov twg los ntawm 95% mus txog 99.5%, thiab qhov kawg ntawm qhov ntau yam uas tus neeg yuav khoom xav tau nyob ntawm seb nws yuav mus rau qhov twg. Cov kuab tshuaj- cov khoom qib - sib tov, txheej txheej, ntxuav cov qauv - feem ntau yog qhov zoo ntawm ntau dua lossis sib npaug li 98% (GC), thiab them nyiaj ntau dua qhov feem ntau tsis yuav khoom muaj txiaj ntsig. Phthalic anhydride ntau lawm yog ib qho chaw cov neeg yuav khoom yuav tsum thawb ntau dua lossis sib npaug li 99% nrog kev tswj hwm nruj, txij li isomer nqa los yog cov dej seem hauv cov khoom tuaj yeem ntsiag to luv lub neej catalyst thiab rub tawm los ntawm lub sijhawm. COA tsim nyog ntseeg tau qhia peb tus lej ua ke - GC purity, dej cov ntsiab lus (Karl Fischer), isomer piv - vim hais tias ib leeg ntawm lawv ib leeg tuaj yeem zais qhov uas ob tus yuav ntes tau.
Qhov ceev ntawm o-Xylene
Qhov ceev ntawm o-Xylene zaum ntawm li 0.880 g/cm³ (0.8802 g/mL) ntawm 20 degree, qhov hnyav tshaj ntawm peb xylene isomers - m-xylene khiav ze rau 0.864, p-.8 xylene Qhov sib txawv ntawd yog me me ntawm daim ntawv tab sis muaj txiaj ntsig zoo hauv kev xyaum: ib qho kev nyeem ntawv pom zoo tawm ntawm 0.880 feem ntau yog isomer drift, tsis yog qhov ntsuas tsis zoo. Qhov kev ntes yog qhov kub thiab txias - qhov ceev txav txaus nrog nws tias kev sib piv ob qhov kev nyeem ntawm qhov kub sib txawv tuaj yeem zoo li qhov tsis ua tiav spec thaum tsis muaj dab tsi tiag tiag. Sib piv qhov ntsuas kub rau qhov twg tus neeg siv khoom siv los ua lawv cov ntaub ntawv ua ntej. o-Xylene tsis sib tov nrog dej tab sis dissolves dawb hauv feem ntau cov kuab tshuaj organic, uas taug qab nrog nws cov tshuaj pleev tsis zoo, muaj ntxhiab tsw.
Saib Kom Paub o-Xylene Product Information
Boiling Point ntawm o-Xylene
Qhov kub ntawm o-Xylene nyob ib ncig ntawm 144.4℃(291.9℃F), qhov siab tshaj plaws ntawm peb xylene isomers, thiab yog vim li cas tag nrho cov distillation tuaj yeem rub nws tawm ntawm cov dej sib xyaw xylene ntawm cov nroj tsuag nplai. Cov npoo saum toj m-xylene (139.1 degree) tsuas yog kwv yees li 5℃- txaus rau qhov nruj, zoo-khiav kem, tab sis tsis muaj ntau chav rau kev ua yuam kev, uas yog vim li cas boiling - ntau yam drift yog feem ntau thawj kos npe rau tus neeg muag khoom txoj kev yog slipping, ua ntej purity tooj txawm txav. Melting point yog nyob ib ncig ntawm -25.2℃(-13.4℃F), yog li nws nyob twj ywm kua los ntawm lub hauv paus ib qho chaw cia los yog thauj. Flash point zaum ze 32 degree, tus qauv flammable-kua thaj chaw rau leej twg twb tuav cov kuab tshuaj tsw qab.
