Abstract: A probe head with a cylindrical portion and an oblique truncated portion angled downward toward a high-powered electronic device under testing. The probe head has a proximal end comprising an oblique truncated cone portion angled relative to the longitudinal axis at an input angle and has an analog signal input. The probe head has a digital signal output provided on the distal end of the housing.

Abstract: The present invention relates to a process for preparing hydroformylation products of olefins having at least four carbon atoms, in which a high proportion of both the linear Ci-olefins having a terminal double bond comprised in the olefin-comprising feed used and of the linear Ci-olefins having an internal double bond is converted into hydroformylation products. Furthermore, the invention relates to a process for preparing 2-propylheptanol which comprises such a hydroformylation process.

Abstract: The present invention relates to a process for preparing deodorized 1,2-propanediol, to the use of the purified propanediol and to an apparatus for performing the process.

Abstract: A process for preparing 2-{1-[2-(4-chlorophenoxy)propoxyimino]-butyl}-3-hydroxy-5-(tetrahydrothiopyran-3-yl)cyclohex-2-enone lithium salt by reacting the corresponding acid 2-{1-[2-(4-chlorophenoxy)-propoxyimino]butyl}-3-hydroxy-5-(tetrahydrothiopyran-3-yl)-cyclohex-2-enone and lithium hydroxide and the isolation of the lithium salt are described. Here, it is advantageous to use a solvent mixture which comprises methanol and at least one aromatic hydrocarbon and to remove at least some of the solvent prior to the isolation. It is particularly preferred to dissolve the acid in an aromatic hydrocarbon, preferably toluene, and to use a methanolic lithium hydroxide solution. The product, which can be obtained in a more efficient manner by this process, furthermore has considerable advantages with respect to formulation.

Abstract: The present invention relates to a process for the continuous preparation of methoxyamine hydrochloride by cleavage of acetone oxime methyl ether by means of hydrogen chloride and water, wherein the cleavage is carried out in a reaction column having less than 20 theoretical plates and the amount taken off at the top is set to at least 30% of the amount of feed.

Abstract: A process for the simultaneous production of dicarboxylic acids and diamines from a) polymers based on polyamides of dicarboxylic acids or their derivatives with diamines, orb) compositions containing essentially such polymers, by splitting these polymers into their monomeric constituents, comprises treating these polymers or compounds with a base in alcoholic medium, and subsequently converting the resulting dicarboxylate salts electrochemically into the corresponding dicarboxylic acids and bases.

Abstract: Preparation of mixtures of O-phenoxyalkylhydroxylamines Ia and Ib ##STR1## and the corresponding salt mixtures by a) converting mixtures of isomers of O-(2-hydroxyethyl)oximes IIa and IIb ##STR2## with a sulfonyl halide III ##STR3## into a mixture of sulfonates IVa and IVb ##STR4## b) reacting this mixture of IVa and IVb with a phenol HO-Ar (V) to give a mixture of O-phenoxyalkoximes VIa and VIb ##STR5## c) hydrolyzing this mixture in the presence of an acid and, if desired d) liberating the O-phenoxyalkylhydroxylamines Ia and Ib from the resulting salts using a mineral acid.Compounds Ia/Ib and VIa/VIb are important intermediates for crop protection agents.
