| Category | Details |
|---|---|
| Sectoral Uses | - Textile: Protection of fabrics and garments - Chemical Industry: Production of dyes, varnishes, plastics, rubber - Laboratory: Reagent in organic synthesis and analysis |
| Reasons for Preference | - Strong odor and quick effectiveness - Low cost - Easy to use (tablet form) - Long shelf life |
| Alternative Products | - Paradichlorobenzene (PDB) - Natural solutions: Lavender, cedarwood oil - Modern insecticides: Pyrethroid-based sprays |
| Usage Quantities | - Household: 1–2 tablets for small closets/drawers - Industrial storage: Larger amounts depending on volume, evenly distributed - Laboratory: Precisely measured as reagent |
| Precautions During Use | - Ensure good ventilation - Use gloves, avoid direct contact - Do not place tablets directly on fabrics (risk of staining) - Keep away from children and pets - Store in sealed containers |
A sector-based comparison of naphthalene and its alternatives::
| Sector / Usage Reason | Naphthalene (C10H8) | Paradichlorobenzene (PDB) | Natural Alternatives (Lavender, Cedarwood Oil) | Modern Insecticides (Pyrethroid Sprays) |
|---|---|---|---|---|
| Textile Protection | Strong odor, effective against moths and larvae | Similar moth repellent, less flammable | Pleasant scent, eco-friendly, less potent | Highly effective, targeted action, higher cost |
| Chemical Industry | Intermediate for dyes, resins, plastics, rubber | Limited industrial use | Not applicable | Not applicable |
| Paints & Varnishes | Raw material in certain formulations | Rarely used | Not applicable | Not applicable |
| Laboratory Applications | Reagent in organic synthesis and analysis | Occasionally used in research | Not applicable | Specialized reagents only |
| Household Use | Common mothballs/tablets for closets and storage | Widely used as mothballs | Sachets, cedar blocks, safer but weaker | Sprays for direct insect control, fast action |
