p-Xylene (PX) yog ib qho tseem ceeb ntawm cov organic chemical raw khoom, feem ntau yog siv los tsim cov terephthalic acid (PTA), uas yog siv los tsim cov khoom kawg xws li polyester fibers thiab lub raj mis yas.
Paraxylene (CAS: 106-42-3) rau polyester
Paraxylene (CAS: 106-42-3) yog ib qho tseem ceeb ntawm kev sib txuas ntawm petrochemical, textile, thiab ntim kev lag luam. Thoob plaws ntiaj teb, ntau dua 90% ntawm PX yog siv los tsim PTA. Cov ntawv thov tshwj xeeb yog raws li hauv qab no:
Main siv:
PTA ntau lawm: PX reacts nrog oxygen nyob rau hauv lub reactor los tsim PTA. PTA yog tom qab ntawd polymerized nrog ethylene glycol (EG) los tsim polyethylene terephthalate (PET)-PET yog ib qho ntawm lub ntiaj teb siab tshaj - tsim cov khoom hluavtaws, dav siv hauv:
Kev lag luam textile: Nws yog siv los tsim cov polyester fibers (xws li polyester), suav txog ntau dua 70% ntawm cov khoom siv hluavtaws thoob ntiaj teb, siv rau hauv cov khaub ncaws, tsev textiles, thiab fabrics industrial (xws li canvas thiab lim ntaub).
Ntim: Paraxylylene (PX) tuaj yeem siv los ua cov khoom siv raw rau kev ua PET lub raj mis yas (xws li lub raj mis dej haus thiab lub raj mis roj ua noj) thiab cov khoom ntim cov yeeb yaj kiab. Vim nws qhov siab pob tshab, cuam tshuam tsis kam, thiab rov ua haujlwm zoo, nws yog qhov hloov pauv rau cov iav tsoos thiab ntim PVC.
Engineering Plastics: Los ntawm kev hloov kho, siab - lub zog PET engineering plastics xws li paraxylylene (CAS: 106-42-3) yog tsim thiab siv rau cov khoom siv tsheb (xws li lub pob thiab cov dashboards) thiab cov khoom siv hluav taws xob.
Lwm yam kev siv:Me me ntawmParaxylylene (PX)yog siv nyob rau hauv zus tau tej cov coatings, dyes, tshuaj intermediates (xws li p-diamine), thiab raws li ib tug hnyav (tab sis vim nws flammability, no hnyav siv tau maj mam hloov los ntawm lwm yam kev nyab xeeb).
Lub cev muaj zog ntawm paraxylylene: Tsawg-boiling-point aromatic hydrocarbon
- Cov tsos mob thiab lub xeev: tsis muaj xim, pob tshab kua; paraxylylene muaj ntxhiab tsw ntxhiab tsw (zoo ib yam li benzene, tab sis me dua).
- Cov ntsiab lus boiling thiab melting: qis boiling point (kwv yees li 138.4 degree), volatile heev; melting point yog 13.2 degree. Cov yam ntxwv no ua rau nws khov rau hauv cov pob zeb dawb ntawm qhov kub thiab txias (xws li thaum lub caij ntuj no), yuav tsum tau ceev faj qhov kub thiab txias (feem ntau siab dua 15℃kom tsis txhob muaj zog).
- Solubility: Paraxylylene yog soluble nyob rau hauv dej (solubility tsuas yog hais txog 19 mg / L ntawm 20 degree), yooj yim soluble nyob rau hauv ethanol, benzene, thiab lwm yam organic solvents, thiab yog ib tug raug tsis yog -polar hnyav.
- Qhov ceev thiab Volatility: Paraxylylene (PX) muaj cov kua ntom tsawg dua dej (kwv yees li 0.861 g / cm³ ntawm 20 degree) thiab vapor density ntau dua huab cua (kwv yees li 3.66, huab cua=1). Tom qab cov pa xau, cov vapor nyiam nyob rau hauv av lossis hauv qhov chaw qis - pw, ua rau muaj kev pheej hmoo ntawm combustion thiab tawg.
- Kev ruaj ntseg: Paraxylylene (PX) yog tshuaj lom neeg ruaj khov ntawm chav tsev kub thiab tsis yog -corrosive, tab sis kev sib cuag nrog cov muaj zog oxidizers thiab qhov chaw ntawm hluav taws xob yuav tsum raug zam.
