Product Description
Refined Naphthalene yog qhov tseem ceeb tshaj plaws condensed-nuclei aromatics hauv kev lag luam. Nws Molecular Formula yog C10H8, uas yog cov thee tar cov khoom siv ntau tshaj plaws, thiab
Feem ntau nws yog tsim los ntawm kev rov ua dua los ntawm distilling thee tar thiab coke-kub roj los yog los ntawm kev ua kom huv theem nrab ntawm kev lag luam naphthalene
