p-Xylene (CAS 106-42-3) yog dab tsi?
CAS 106{1}}42-3 p-Xylene, tseem hu ua 1,4-dimethylbenzene lossis para-xylene, yog ib qho tsis muaj xim, flammable kua aromatic hydrocarbon nrog cov tshuaj formula C₈H₁₀ thiab molecular hnyav ntawm 106.16 g/mol. Nws yog ib qho ntawm peb hom isomeric ntawm xylene (nrog rau o-xylene thiab m-xylene) thiab ua haujlwm feem ntau yog cov khoom noj tseem ceeb hauv kev lag luam tshuaj rau kev tsim cov terephthalic acid thiab dimethyl terephthalate, uas yog qhov tseem ceeb precursors rau polyethylene terephthalate (polyethylene terephthalate). Nrog ib tug qab zib tsw thiab solubility tsawg nyob rau hauv dej (0.165 g / L ntawm 25 degree), p-xylene yog miscible nyob rau hauv organic solvents xws li ethanol, ether, thiab benzene.

p-Xylene (CAS 106-42-3) Siv rau dab tsi?
Polyester ntau lawm: p-xylene feem ntau yog siv los ua tus thawj coj rau purified terephthalic acid (PTA) thiab dimethyl terephthalate (DMT), uas yog ob qho tib si tseem ceeb monomers hauv polyester manufacturing.
PET yas yog siv los tsim cov khoom siv PET, uas tuaj yeem tsim rau hauv lub teeb yuag, siab - lub hwj muaj zog thiab cov ntim khoom noj.
Fibers thiab textiles: Paraxylene cov ntaub ntawv polyester fibers siv nyob rau hauv cov khaub ncaws, ntaub pua plag thiab cov khoom siv sab hauv.
Lwm yam kev siv: Nws kuj yog siv los ua cov kuab tshuaj, hauv tshuaj tua kab thiab ua ib feem ntawm qee yam tshuaj.
