Codsiga
1.It waa sheyga ugu muhiimsan ee soo saara phthalic anhydride, dheesha, resin, α-naphthalene acid, saccharin iyo wixii la mid ah.
2.Waa daamurka dhuxusha ee ugu badan, badanaana waxa lagu soo saaraa dib-u-warshadeynta laga bilaabo nadiifinta daamurka dhuxusha iyo gaaska kookaha ama nadiifinta labaad ee naphthalene warshadaha.
Kaydinta
Naphthalene la safeeyey waa in lagu kaydiyaa bakhaar qallalan oo hawo leh, Alaabtaani waxay iska leedahay adkaha guban kara, waa in ay ka fogaato isha dabka iyo walxaha kale ee guban kara.
