Stabilized aminobenzotrifluorides

A method of increasing the storage stability and the thermal stability of aminobenzotrifluorides of the formula (I) ##STR8## in which R.sup.1 and R.sup.2 independently of each other, are hydrogen, C.sub.1 -C.sub.6 -alkyl, C.sub.2 -C.sub.6 -alkenyl, substituted or unsubstituted aryl, halogen, CF.sub.3, nitro, amino, methoxy, hydroxyl, or NR.sup.3 R.sup.4, where R.sup.3 and R.sup.4, independent of each other are hydrogen or C.sub.1 -C.sub.5 -alkyl radicals, and the NH.sub.2 group can be located in the 2-, 3-, or 4-position in relation to the CF.sub.3 group, comprising the step of

• adding a base to said aminobenzotrifluoride, said base comprising a primary, secondary, or tertiary amine of the formulae (IIa) or (IIb) or a cycloaliphatic amine of the formula (IIc) ##STR9## in which R.sup.5, R.sup.6, and R.sup.7, independently of each other, are in each case hydrogen, C.sub.1 -C.sub.20 -alkyl, C.sub.5 -C.sub.6 -cycloalkyl or CY.sup.1 Y.sup.2 -aryl, where Y.sup.1 and Y.sup.2 independently of each other, are C.sub.1 -C.sub.4 -alkyl, aryl, or hydrogen, and aryl is phenyl, aminophenyl, hydroxyphenyl, tolyl, xylyl, nitrophenyl or halophenyl,
• R.sup.8, R.sup.9, R.sup.10, R.sup.11, R.sup.12, in each case independently of each other, are hydrogen or C.sub.1 -C.sub.3 -alkyl, where R.sup.12 can additionally have the meaning of --(CR.sup.13 R.sup.14).sub.p --, R.sup.13 and .sup.14, independently of each other, are hydrogen or methyl,
• m is an integer from 1 to 2,
• n is an integer from 2 to 3,
• p is an integer from 1 to 6, and
• q is an integer from 1 to 4.
