Khoom Piav Qhia
Refined Nafhalene yog qhov tseem ceeb tshaj plaws condensed-nuclei aromatics hauv kev lag luam. Nws molecular qauv molecular yog c10h8, uas yog cov thee tar feem ntau muaj ntau nplua mias, thiab
Feem ntau nws yog tsim los ntawm kev rov ua dua tshiab ntawm cov pob zeb distilling thee thiab cov roj coke ntawm kev ua kom huv si ntawm kev lag luam naphthalene
