Aniline → HCID 20347054, compound

Participants

Reaction Steps

170 g of aniline, 5 g of aluminium granules and 15 g of anhydrous aluminium chloride are heated in a steel autoclave to 300° C. and 300 g of pent-1-ene are pumped in over the course of about 5 hours, until the internal pressure is 300 atmospheres gauge. The batch is then kept at 300° C. for a further 6 hours, in the course of which the internal pressure drops to 107 atmospheres gauge. After it has cooled, the content of the autoclave is stirred with 500 ml of benzene, 250 ml of 40% strength sodium hydroxide solution and 300 ml of water for 15 minutes at 30°-40° C. and the benzene layer is washed with water, dried over potassium carbonate and fractionated. 113 g of 2-mono-pent-2-yl-aniline, boiling point 78°-82° C./0.6 mm Hg, and 131 g of 2,6-bis-pent-2-yl-aniline, boiling point 168°-174° C./1.5 mm Hg are obtained.
