4. Preparation of Acenaphthylene

Acenaphthalene can be prepared by acenaphthene through vapor-phase catalytic dehydrogenation. Put industrial acenaphthene into molten kettle, use an indirect steam heat it to melt, then use compressed air press acenaphthene liquid into the spiral mixer gasification. After heating the mixture to about 450 °C, let the mixture into dehydrogenation reactor for catalytic dehydrogenation, condense and dry the product.

5.Uses of Acenaphthylene

Acenaphthalene can be used for determinating aryl aldehyde. And it can be used to get 1,2-dichloro-acenaphthene. This reaction will need reagents iodosobenzene and HCl-silica gel and solvent solid. The reaction time is 5 minutes at ambient temperature. The yield is about 31%.

6.Safety information of Acenaphthalene

This chemical is highly flammable, harmful if swallowed and irritating to eyes, respiratory system and skin. It may cause lung damage if swallowed and may cause drowsiness and dizziness. In addition, it is very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. And it has danger of very serious irreversible effects through inhalation, in contact with skin and if swallowed. During using it, avoid release to the environment and wear suitable protective clothing, gloves and eye/face protection. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.). This material and its container must be disposed of as hazardous waste. And you should refer to special instructions/safety data sheets. If swallowed, do not induce vomitting; seek medical advice immediately and show this container or label. Keep away from sources of ignition and keep container tightly closed at last.
