Tshuaj Tiv Thaiv: Nws kuj tseem siv tau los ntawm cov khoom lag luam xws li roj lubricating, diesel thiab roj hydraulic tiv thaiv oxidation thiab kev tsis pom zoo.
Kev kuaj xyuas cov txheej txheem
Cov tsos thiab cov khoom tshuaj xyuas
Soj ntsuam cov xim, cov duab thiab lwm yam kev pom zoo ntawm cov qauv hauv qab lub teeb. 2,4, {{6- tri-tert-butylphenol feem ntau yog lub teeb daj rau daj crystalline hmoov lossis thaiv.
Kuaj seb cov qauv puas muaj qhov txawv txav xws li agglomeration, disquolation, etcority, nws yuav cuam tshuam qhov tseeb ntawm cov txiaj ntsig ntawm kev ntsuas. Kev soj ntsuam ntxiv ntawm qhov ua rau lossis rov sau cov qauv ntawm cov tshuaj yuav tsum tau ua.
Cov Cuab Yeej Siv Vaj Tse
MELTING TSIAJ LUAM Kev txiav txim: Siv lub suab paj nruag yaj los txiav txim siab melting point ntawm tus qauv. Lub ntsiab lus melting ntawm 2,4, {{6- tri-tert-butylphenol feem ntau nruab nrab {5}} degree.
Kev Ntsuas Boiling Kev Txiav Txim: Siv lub qhov cub npau npau txiav los ua cov ntsuas kom ua kom sov cov qauv hauv qab cov qauv cua hauv siab thiab saib qhov kub thiab txias thaum nws npau. Nws qhov cub npau npau yog hais txog 277 degree.
Kev txiav txim siab ntom ntom: Cov ntsuas ntsuas kom zoo xws li kev siv hluav taws xob kom ntsuas tau los ntsuas qhov ntaug ntawm cov qauv los txiav txim siab tias nws cov phiaj xwm lub cev tau raws li cov kev cai.
Cov Khoom Siv Khoom Siv Khoom Siv Khoom Siv
Nrhiav kom paub meej:
Roj chromatography (GC): Kev txhaj tshuaj kom sib cais los ntawm cov cim ntsuas thiab lub sijhawm ua kom muaj ntau dua lossis sib npaug rau 97.5%.
Kev ua kom zoo ua kua chromatography (HPLC): Kev xaiv kem, mobile theem sib cais thiab cov ntsiab lus yog txiav txim siab los ntawm kev sib piv cov qauv khoom ntawm cov qauv khoom.
Mass Spectrometry (MS): Kev sib cais thiab nrhiav kom tau raws li qhov sib zog ntawm kev txiav txim siab tom qab kev txiav txim siab raws li Ion Peak, thiab paub tseeb.
Cov ntaub ntawv ua haujlwm pab pawg: Siv Infrared Spectrometer los ntsuas lub spectrum, txiav txim siab benzene lub nplhaib, hydroxene pawg ua raws li cov xeeb ceem peaks, thiab paub cov yam ntxwv sib xyaw.
