Process for preparing isopropenyl phenol |
| abstract |
A novel process for producing isopropenyl phenol such as p-isopropenyl phenol which comprises continuously feeding oligomers of isopropenyl phenol having a degree of polymerization of 2 to 5 into a high-boiling inert organic reaction medium such as an alkylnaphthalene heated at 150 DEG to 250 DEG C. under a pressure of 10 to 100 mmHg while maintaining the concentration of the oligomers in the reaction medium at not more than 30% by weight, thereby thermally decomposing the oligomers in the reaction medium; and continuously distilling off the resulting isopropenyl phenol out of the reaction system and recovering it. The process almost quantitatively gives isopropenyl phenol having reduced contents of impurities. |
