Trifluoroanisoles of the formula
where m is 1 or 2 and n is 0 to 3, are prepared by reacting hydrogen fluoride with trichloroanisoles of the formula
in the vapor phase, in the presence of a fluorinated alumina catalyst wherein X is halogen other than flourine; R is aryl, halogen substituted aryl, halogen, alkyl, or alkoxy; w is 0 to 2; p is 1 to 3; q is 0 to 2; w + p + q is 3; W is 1 to 3 and is greater than w; p' is 0 and 2 and is less than p; q' is 0 and 2 and is equal to q; and w' + p' + q' is 3.
式中 m 为 1 或 2,n 为 0 至 3 的三氟苯甲醚是在氟化氧化铝催化剂存在下,通过氟化氢与式中的三氯苯甲醚在气相中反应制备的,其中 X 为除面粉以外的卤素;R 为芳基、卤素取代的芳基、卤素、烷基或烷氧基;w 为 0 至 2;p 为 1 至 3;q 为 0 至 2;w + p + q 为 3;W 为 1 至 3 且大于 w;p' 为 0 和 2 且小于 p;q' 为 0 和 2 且等于 q;w' + p' + q' 为 3。
