Abstract

2-(Tri-fluoro-methyl)-phenol and 4-(tri-fluoro-methyl)-phe nol respectively are prepd. by boiling a mixt. of either 2-(tri-fluoro-methyl)-chloro -benzene or 4-(tri-fluoro methyl)- chloro-benzene, benzyl-alcohol and of an alkali-hydroxide. A phenyl-benzyl ether intermediate is obtd. which is hydrogenated catalytically to the respective phenol. Water formed during boiling is removed by distillation. The product is purified by vacuum distillation at 50-150 deg.C in the presence of 0.001 pts. wt. silicone oil. A silicone oil additive is also used for products stabilisation.
