Xylener
Xylener er en hvilken som helst af tre isomerer af dimethylbenzen eller en kombination deraf. Alle er farveløse, brandfarlige væsker sammensat af en central benzenring med to methylgrupper knyttet til substituenter. De kan anvendes som prækursorkemikalier og opløsningsmidler.
Xylener er brandfarlige petrokemiske produkter, der kan fremstilles via katalytisk reformering og kulkarbonisering under koksproduktion og findes i råolie, benzin og flybrændstof. Xylener blev først isoleret fra trætjære og navngivet af den franske kemiker Auguste Cahours.
Hvad er Xylene?
Xylen, mere passende kaldet xylener, refererer til enhver enkelt eller kombination af de tre isomerer af dimethylbenzen. De isomere former betegnes som ortho- (o-), meta- (m-) og para- (p-), en reference til carbonet i benzenringen, hvortil de to methylgrupper er knyttet.
- o-isomer: 1,2-dimethylbenzen
- m-isomer: 1,3-dimethylbenzen
- p-isomer: 1,4-dimethylbenzen
Xylener er farveløse og kan påvises ved lugt i koncentrationer så lave som 0,08 til 3,7 ppm i luft og smages i vand ved 0,53 til 1,8 ppm.
Se analysecertifikatet eller sikkerhedsdatabladet for specifik information om xylendensitet og sikkerhedsrisici.
Hvad bruges xylen til?
Industrielle anvendelser
p-Xylen er en forløber for terephthalsyre og dimethylterephthalat, der bruges til fremstilling af polyethylenterephthalat plastflasker og polyesterbeklædning.
Xylen kan bruges som opløsningsmiddel og er en almindelig komponent i blæk, gummi, klæbemidler og maling- og lakfortyndere. Xylener kan bruges til at rense stål, siliciumskiver og integrerede kredsløb. Medicinske anvendelser omfatter brug som opløsningsmiddel af dentale materialer og ørevoks.
Laboratoriebrug
Xylen kan bruges med tøris i bade, til at fjerne olie fra mikroskopobjektiver og som rengøringsmiddel eller monteringsmateriale i histologiske procedurer.
