摘要:
The invention relates to a composite insect attractant for male cabbage moths (Mamestra brassicae) containing (Z)-11-hexadecenyl acetate and (Z)-11-heptadecenyl acetate as active agents in a weight ratio of 70 to 90:80 to 1, optionally along with a liquid or solid adjuvant. An insect trap can contain the composition which is used for attracting and trapping cabbage moth. Their mating is disrupted by air permeation techniques. (Z)-11-heptadecenyl acetate is a synergistically active new compound. The composition according to the invention produces a significantly stronger stimulating reaction on male cabbage moths than the known sex lure compositions.

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 which p1 R 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.
摘要:
The invention relates to a novel process for the halogenation in 2-position of ergot alkaloids. The process is characterized by that as a halogenating agent a system consisting of dimethylsulfoxide, a trialkylhalosilane or triarylhalosilane and optionally a hydrogen halide is used.
摘要:
The invention relates to a new process for preparing novel racemic and optically active 9- or 11-nitroapovincaminic acid derivatives of the general formula (I) ##STR1## wherein R stands for a --CO--X group, wherein X means a halogen atom; orfor a --CO--OR.sup.1 group, wherein R.sup.1 means an optionally mono- or polysubstituted C.sub.1-10 aliphatic group, a C.sub.3-8 alicyclic group or an aromatic C.sub.6-14 hydrocarbyl group; orfor a --CO--NR.sup.2 R.sup.3 group, wherein R.sup.2 and R.sup.3 are the same or different and stand for a hydrogen atom or a C.sub.1-8 alkyl group optionally forming a saturated heterocycle together with the adjacent nitrogen atom and optionally with one or more further nitrogen atoms or other heteroatoms, and R.sup.3 may also represent an amino group when R.sup.2 stands for a hydrogen atom; orfor a cyano group,as well as their salts and pharmaceutical preparations containing these compounds. Furthermore the invention relates to a process for preparing these compounds and preparations.The racemic and optically active substances of the general formula (I) as well as their pharmaceutically acceptable acid addition and quaternary salts have valuable therapeutic properties, namely vasodilating, spasmolytic, antihypoxic and anticonvulsive effects.
摘要:
A process for the continuous drying of chemical products by milling fluidization, in which a fluidized bed of particles of an inert carrier, e.g., quartz sand having a particle diameter of 0.5-1.0 mm., is maintained and the chemical product to be dried is introduced in a wet state, e.g., wet solid or paste or suspension, into the fluidized carrier bed. The chemical product dries on the surface of the inert carrier particles and dry particles of the chemical product leave the relatively large and heavy carrier particles and are carried off in the exit gas. The carrier particles, however, are too large and heavy to leave in the exit gas and so remain in the fluidized bed. If desired, the dried product particles can be further dried, for example by additional drying gas in a cyclone chamber, after which the dried particles are separated from the gas which can be vented and/or recycled.
摘要:
New intermediate compounds are disclosed of the formula I, ##STR1## wherein R.sub.1 and R.sub.2 are independently alkyl having 1 to 4 carbon atoms,or acid-addition salts thereof of formula Ib, ##STR2## wherein X represents an acid residue, and a process for the preparation of the intermediate compounds.
摘要:
An antifungal or anthelmintic method of treatment is disclosed which comprises the step of administering to a mammal in need of said treatment, a pharmaceutically effective amount of a compound of the Formula (I) ##STR1## wherein X is halogen, C.sub.1 to C.sub.6 alkoxy, or a group --NRR.sup.1 in which R and R.sup.1 are each hydrogen or C.sub.1 to C.sub.6 alkyl; andR.sup.2 is hydrogen, halogen, C.sub.1 to C.sub.6 alkyl, C.sub.1 to C.sub.6 alkoxy, phenyl, phenylthio, or phenyl or phenylthio substituted by at least one halogen or amino substituent; or a pharmaceutically acceptable acid addition salt thereof.
