Kev piav qhia txog khoom
Refined Naphthalene yog qhov tseem ceeb tshaj plaws condensed-nuclei aromatics hauv kev lag luam. Nws cov mis molecular yog C10H8, uas yog cov khoom muaj ntau tshaj plaws ntawm cov thee tar, thiab
feem ntau nws yog tsim los ntawm kev siv dua los ntawm kev ua kom cov thee tar thiab cov roj coke-qhov cub lossis los ntawm kev ntxuav qib ob ntawm cov naphthalene hauv kev lag luam.

Daim Ntawv Thov
1. Nws yog cov khoom siv tseem ceeb ntawm kev tsim cov phthalic anhydride, dyestuff, resin, α- naphthalene acid, saccharin thiab lwm yam.
2. Nws yog cov khoom muaj ntau tshaj plaws ntawm cov thee tar, thiab feem ntau nws yog tsim los ntawm kev siv dua los ntawm kev distilling thee tar thiab coke qhov cub roj lossis los ntawm kev ntxuav thib ob ntawm kev lag luam naphthalene.
Kev Khaws Cia
Cov Naphthalene uas tau ua kom huv si yuav tsum khaws cia rau hauv qhov chaw qhuav thiab muaj cua nkag tau, cov khoom no yog cov khoom uas yooj yim hlawv, yuav tsum nyob deb ntawm qhov chaw hluav taws thiab lwm yam khoom siv uas yooj yim hlawv.
