Process for the preparation of alkoxytriazolinones

The present invention relates to a novel process for preparing triazolinones of the general formula (I) ##STR1## in which R.sup.1 represents halogenoalkyl, and

Alkoxytriazolinones of the formula (I), ##STR1## are obtained in good yields and in high purity by reacting iminocarbonic diesters (II) with carbazinic esters (III) ##STR2## at -20.degree. C. to +120.degree. C. (1st step) and subjecting the semicarbazide derivatives (IV) formed in this process with elimination of R.sup.2 --OH ##STR3## to a cyclizing condensation reaction in the presence of a base at 20.degree. C. to 150.degree. C. with elimination of R.sup.3 --OH, if appropriate (2nd step) and, finally, by reacting the resulting 5-alkoxytriazolinones of the formula (V) �=formula (I) where R.sup.1 =H! with an alkylating agent of the formula R.sup.1 --X (VI) at 0.degree.
