| Benzene and nitrobenzene are heavier than water and they are settling on the river bottom or sticking to the ice. |
| Aniline is manufactured by reduction of nitrobenzene, using hydrogen gas and a copper catalyst, or using iron, water, and hydrochloric acid for the reduction. |
| When this liquid was treated with a few drops of nitric acid mixture the smell of nitrobenzene was given off. |
| The residue of nitric acid which replaces hydrogen in benzene is the nitro-group, and the compound is nitrobenzene. |
| The nitrobenzoate is insoluble in ether alcohol, but is soluble in acetone, acetic acid, and nitrobenzene. |
| The purity of the product depends upon the quality of the benzene from which the nitrobenzene was prepared. |
