    摘要: A process for the dehydration of substances, mixtures, primarily condensation reaction mixtures, (e.g. direct esterification, direct acetal formation, direct ketal formation), performed by continuous azeotropic distillation with an organic solvent forming with water an azeotropic mixture of minimal boiling point and unable to mix with water, carried out in such a way that the distillate is cooled at least to the temperature, at which the condensate with the given water content or the organic phase of the condensate is just supersaturated with respect to water, and the organic phase of lower water content obtained in this way is recycled to the distilling boiler. The organic solvents used are e.g. benzene, toluene, 1,2-dichloroethane, chloroform, carbon tetrachloride.

    摘要: The invention relates to acaricidal compositions containing as active ingredient: the fermentation broth or cell-free fermentation broth, of a concentrate of the fermentation broth or cell-free fermentation broth, or a solidified form of the fermentation broth or cell-free fermentation broth of one or two bacterium strains deposited at the National Collection of Agricultural and Industrial Microorganisms, Budapest, Hungary under the identification Nos. 001083 and 001086 or of their mixed micropopulation, if desired, in a sterilized state, optionally together with the metabolism products arising during the fermentation and inutilized nutriments, as well as one or more solid and/or liquid carrier(s) (preferably sugar or a grist of natural minerals), or an inert solvent (e.g. water) and, if desired, with surface active (preferably anionic or nonionic emulsifying or dispersing) agents. The compositions according to the invention can be used for protecting Apis mellifera (honey bee) against mites, particularly Varroa jacobsoni.

    摘要: The invention relates to a new process for the preparation of aminodiaryl sulfoxide derivatives of the formula (I), ##STR1## wherein X is halogen, alkoxy having from 1 to 6 carbon atoms or a group --(N,R,R.sup.1), in whichR and R.sup.1 are hydrogen or alkyl having from 1 to 6 carbon atoms,R.sup.2 is hydrogen, halogen, alkyl having from 1 to 6 carbon atoms, alkoxy having from 1 to 6 carbon atoms or phenyl or phenylthio both optionally substituted by one or more identical or different halogen(s) and/or amino group(s),and acid addition salts thereof.The compounds of formula (I) are pharmaceutically active, in particular are potent anthelmintics, or can be used as active ingredients in pesticidal compositions. The invention therefore relates to pharmaceutical and pesticidal compositions containing compounds of formula (I) or salts thereof as active ingredient.Compounds of formula (I), in which the substituents are as defined above, but if X stands for a group --N(R,R.sup.1) in which R and R.sup.1 both represent hydrogen, and X is in para-position related to the sulfoxide group, then R.sup.2 is other than hydrogen, halogen, alkyl having from 1 to 6 carbon atoms and alkoxy having from 1 to 6 carbon atoms, and the acid addition salts thereof, are new. These new compounds are also subject of the present invention.
