Lub npe 1,2-dimethylbenzene yog dab tsi?
Lub npe nrov rau 1,2-dimethylbenzene yogo-xylene(los yog ortho-xylene).
Lwm lub npe: o-Xylene; 1,2-xylene; o-dimethylbenzene hmoov.
1,2-dimethylbenzene hmoovCAS 95-47-6 yog lub hauv paus rau terephthalic acid thiab dimethyl terephthalate, ob qho tib si monomers siv los tsim cov polyethylene terephthalate (PET) lub raj mis yas thiab cov khaub ncaws polyester. Insoluble hauv dej, o-Xylene tuaj yeem ua rau miscible hauv ethanol, ether, chloroform thiab lwm cov kuab tshuaj organic.
