Abstract: Preparation of acetals by reaction of 1 mol. of an unsaturated aldehyde with 1 mol. of an unsaturated alcohol in presence of an acid as catalyst and with separation of the water of reaction is effected by partly reacting the reactants in a column, concentrating the obtained acetal in ≥ 2 sequential evaporation steps and then recycling the recovered reactants to the reaction column. Preparation of acetals (I) by reaction of 1 mol. of an unsaturated aldehyde (II) with 1 mol. of an unsaturated alcohol (III) in presence of an acid as catalyst and with separation of the water of reaction is effected by partly reacting the reactants in a column, concentrating the obtained acetal in ≥ 2 sequential evaporation steps and then recycling the recovered reactants to the reaction column. R - R = H or optionally substituted 1-6C alkyl; and R = H, an optionally mono- or poly-unsaturated, optionally substituted 1-12C alkyl or an optionally substituted 3-12-membered optionally mono- or poly-unsaturated carbon ring.

Abstract: Trifluoromethylphenylazolylmethyloxiranes of the general formula I in which R represents hydrogen, halogen, nitro, phenyl, phenoxy, alkyl, alkoxy, haloalkyl or haloalkoxy, and, moreover, R together with the phenyl ring can also form a naphthyl radical which is unsubstituted or substituted, n represents an integer from 1 to 5, R represents ortho- or para-trifluoromethyl, X represents CH or N, and their acid addition salts and metal salts which are tolerated by plants, and fungicides containing these compounds.
