P - ey xylene (paraxylene, px)yog cov organic sib xyaw nrog cov tshuaj mis nyuj c₈h₁₀, faib ua ib qho ntawm cov muaj ntxhiab tsw muaj ntxhiab hydrocarbons. Nyob rau hauv chav tsev kub, nws yog cov kua tsis muaj xim, kua pob nrog cov ntxhiab tsw ntxhiab, Insoluble tsw, ether, thiab lwm yam etorocs cov kuab tshuaj. Paraxylene (PX) feem ntau yog siv los ua cov khoom siv raw hauv kev tsim cov polyester fibers, cov txiaj ntsig, zas, thiab tshuaj tua kab. Nws tseem ua haujlwm raws li cov kuab tshuaj, cov qauv tshuaj hauv chromatographic tsom xam, thiab nruab nrab hauv nruab nrab hauv cov etthic synthesis.
P -} xyooj siv
- Polyester raw khoom: txog 98% ntawmParaxylene (PX)yog noj nyob rau hauv kev tsim khoom ntawm kev huv terephthalic acid (PTA). PTA polymerizes nrog ethylene glycoles terephathal (tsiaj loj rau polyester fiberate, thiab cov yeeb yaj kiab, siv tau dav hauv textiles, ntim, thiab cov dej haus.
- Muaj cov kuab tshuaj: PX khoom muaj nuj nqi raws li lub siab - Kev ua yeeb yam zoo hauv cov xim tha xim, txhim kho khoom siv solubility thiab ruaj khov.
- Kws Tshuaj thiab Tshuaj lom neeg: ib qho me me ntawm PX tau siv rau synthesizing kws tshuaj nruab nrab (piv txwv, vitamin b1) thiab zas xim ua ntej.
- Lwm cov kev siv: PX cov khoom kuj tseem pom kev siv tsawg rau hauv cov tshuaj tsw qab thiab yas yas.
Vim Li Cas Thiaj YuavP -} ey xyiab (CAS 106-42-3)Los ntawm gneebio?
Gneebioyog ib tug neeg tsim chaw tsim khoom thiab chaw muag khoom nrog dhau ib xyoo caum ntawm kev paub hauv kev lag luam tshuaj. Peb liP -} ey xyiab (CAS 106-42-3)yog tsim nyob rau hauv txoj kev nruj me me iso thiab GMP cov khoom siv zoo, ua kom muaj kev huv siab loj hauv kev siv cov ntawv thov. Peb muaj:
- Cov khoom lag luam khoom (cov ntaub ntawv cov ntaub ntawv);
- COA thiab MSDS;
