1.A number of catalysts have been investigated in the phenol—isobutene alkylation reaction under comparable conditions, these catalysts including BF3, H3PO4· BF3, AlCl3, H2SO4, and AlCl2 · HSO4; it was shown that boron fluoride, taken in 0.8–1% quantity, is the most active catalyst and gives the highest yield of p-tert-butylphenol.2.An investigation has been made of the effect of various factors on alkylate yield and composition in phenol isobutene alkylation with boron fluoride. The yield of p-tert-butylphenol reaches 78–88% of the theoretical. |
