Abstract: Cpds. of formula (I): (where X is halogen or alkoxy Y = O or S; R2 and R3 are 1 - 6C alkyl opt. substd. by halogen, or R2 + R3 is ethylene) are insecticides esp. active against adult and larval forms of diptera. Preferred are (I) where X = MeO, R2 = R3 = Et and Y = O or S. (I; Y = O) may be prepd. by reacting (II) with (III): (where W = halogen; R4 = alkyl). Cpds. (I) can also be prepd. by reacting an enol or alkali metal enolate of 1-Ph-5-X-pyridazine-4(5H), 6(1H)-dione with Cl(Y)P(OR2)OR3 in an inert solvent in the presence of an acid binder.

Abstract: In a process for the continuous prodn. of lactams by rearrangement of cycloalkanone oximes at 210-450 degrees C on carrier catalysts in a fluidised bed, carry-over of catalyst and other material from the bed into other parts of the appts. and into the crude lactam is reduced by introducing hydroxy cpds. or orthoformic acid esters, or their mixtures with steam, into the reaction space above the fluidised bed in an amount of 0.01-1 kg/kg of cylcoalkanone oxime.

Abstract: In the prepn. of lactans by catalytic rearrangement of cycloalkanonoximes in a turbulent bed, at 210-450 degrees C, of supported catalyst contg. boric acid or a cpd. which forms boric acid under the reaction conditions is passed over the catalyst together with the cycloalkanonoxime. Pref. 0.1-5 wt.% of bron cpd. (w.r.t. cycloalkanonoxime and calc. as B2O3) is passed over the catalyst. The active life of the catalyst is prolonged without the need for a separate re-activation zone.
