| 3, 5-Xylenol, 3, 5-dimethylphenol | 108-68-9 | C8H10O | 122.16 |
Cov khoom siv nruab nrab tseem ceeb hauv kev lag luam, muaj tshuaj lom thiab xeb. Kev tiv thaiv yog qhov tsim nyog thaum lub sijhawm tsim khoom thiab siv.
Xylenols yog cov organic compounds nrog cov mis (CH3)2C6H3OH. Lawv yog cov khoom tsis muaj xim lossis cov kua roj. Lawv yog cov derivatives ntawm phenol nrog ob pawg methyl ntawm ntau qhov chaw piv rau pawg hydroxyl. Muaj rau isomers, uas 2,6-xylenol nrog ob pawg methyl hauv ib qho chaw ortho piv rau pawg hydroxyl yog qhov tseem ceeb tshaj plaws. Lub npe xylenol yog portmanteau ntawm cov lus xylene thiab phenol.
2,4-Dimethylphenol ua ke nrog lwm cov xylenols thiab ntau lwm yam tshuaj sib xyaw ua ke yog rho tawm los ntawm cov thee tar, cov khoom siv volatile tau los ntawm kev tsim cov coke los ntawm cov thee. Cov seem no muaj ob peb feem pua ntawm qhov hnyav ntawm xylenols nrog rau cresols thiab phenol. Cov xylenols tseem ceeb hauv cov tar yog 3,5-, 2,4, thiab 2,3- isomers. 2,6-Xylenol yog tsim los ntawm methylation ntawm phenol siv methanol nyob rau hauv qhov muaj cov hlau oxide catalysts.
Kev yaj: me ntsis soluble hauv dej, soluble heev hauv cawv, ether thiab lwm yam organic solvent.
