    Notes: Wie nach der verschiedenen Kristallgitterstuktur von KCl und TlCl zu erwarten ist, bilden diese beiden Salze  -  entgegen früher veröffentlichten Angeben  -  keine lückenlose Reihe von Mischkristallen. Jedoch vermag jedes der beiden Salze das andere zu einem geringen Betrage von einigen Molprozent in fester Lösung aufzunehmen.

    Notes: In einem Milieu von Strontiumoxyd SrO läßt sich das bisher noch nicht dargestellte Europium(II)-oxyd EuO als Mischkristall stabilisieren. Die Mischkristalle SrO · EuO sind rot gefärbt und besitzen das SrO Kristallgitter. Sie können durch thermische Zersetzung von gemischten Carbonaten (Sr, EuII)CO3. durch Reduktion von SrO · Eu2O3 Gemischen mit Wasserstoff und sogar durch Abpumper von Sauerstoff aus diesen Oxydgemischen erhalten werden. EuO + O2 und Eu2O3 stehen also in Gegenwart von SrO in einem experimentell leicht zugänglichen reversiblen Gleichgewicht. Bei 1000° liegen die Gleichgewichtsdrucke in der Größenordnung von 10-4 Torr.

    Description / Table of Contents: An Alternative Method for Preparation of Bi2Sr2CaCu3Ox, YBa2Cu3O7-δ, and YBa2Cu3-xMxO7-δ (M = Ni, Ag and x ≤ 33 Mol%)Oxidation of quenched melts of metals in a well defined argon/oxygen atmosphere has been found as an alternative method to prepare hight purity samples of Bi2Sr2CaCu2Ox without Pb-stabilization. A special equipment for the oxidation of powder samples will be described. By our new method it is also possible to prepare YBa2Cu3O7-δ and derivatives of this compound, where Cu is substituted by high amounts of Ni or Ag.
    Notes: Es wird eine alternative Präparationsmethode beschrieben, die es ermöglicht, durch Oxidation abgeschreckter Metallschmelzen in einer Sauerstoff-Argon-Strömungsapparatur sehr saubere, nicht Pb-stabilisierte Bi2Sr2CaCu2Ox-Präparate herzustellen. Dieser Weg ist auch für die Darstellung von YBa2Cu3O7-δ und Substitutionsderivaten dieser Verbindung mit hohen Konzentrationen an Ni oder Ag geeignet.

    Notes: The electron-impact and field ionisation spectra of nineteen di- and tetracyanopyrazines are presented. The use of high resolution mass measurement and metastable analysis allows the proposal of some general fragmentation mechanisms. The 5,6-disubstituted (alkyl or arene) 2,3-dicyanopyrazines examined show, apart from a less important loss of the nitrile and dicyano groups, fragmentation of the heterocyclic system directed by the nitrogen atoms. In contrast, anellation in the 5,6-position, leads only to loss of the nitrile and dicyano groups being observed. These general fragmentation mechanisms are also observed for the tetracyanopyrazines examined. A comparison of di- and tetracyanobenzene with five ring heterocycles containing four cyano groups shows that fragmentation of nitrile groups is greatly dependent upon the aromaticity of the cyclic system.

    Spherulite boundary strengthening concept for toughening polypropylene (1998)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part B: Polymer Physics 36 (1998), S. 2047-2056

    Notes: During spherulitic crystallization of polymers, there is a tendency for low molecular weight and other less crystallizable entities to be rejected from the body of the spherulites. This rejection process causes a segregation of these species to those areas where spherulites impinge. As a result of this segregation, lamellar and spherulite boundaries have a tendency to become weak, often resulting in premature mechanical failure. The objective of this work, anthropomorphically speaking, is to develop a melt miscible blend system in which a propylene copolymer “fools” a polypropylene homopolymer into rejecting the copolymer to the spherulite boundaries as an impurity. However, once the copolymer arrives at these boundaries, the copolymer subsequently connects adjacent spherulites through cocrystallization of the propylene copolymer segments. It was found that addition of either a random ethylene-propylene copolymer or an isotactic-atactic block copolymer was able to yield the desired effect. Cocrystallization was confirmed by calorimetry, and segregation of copolymer and subsequent reinforcement at the spherulite boundaries was directly observed microscopically. Using this approach, toughness was increased with little loss in stiffness. © 1998 John Wiley & Sons, Inc. J Polym Sci B: Polym Phys 36: 2047-2056, 1998

    Über Fluorchemie. XVI. Wäßrige Lösungen von Antimontrifluorid und von Fluorwasserstoff als Fluorierungsmittel in der Silicium- und in der Kohlenstoffchemie (1964)

    Description / Table of Contents: Aqueous solutions of SbF3 exhibit strong fluorinating properties even against easily hydrolyzable methyl chlorosilanes and -silanoles. The fluorination probably proceeds through the preceding hydrolysis of Si—Cl bonds yielding silanole groups. The influence o BF3 · 2 H2O on the fluorination by means of aqueous SbF3 has been studied.C—Cl bonds do not react with SbF3 solutions, in aqueous hydrogen fluoride containing 20-40 weight per cent HF, however, the formation of C—F groups occurs at room temperature. The Si—O—Si bond of methyl chlorodisiloxanes is cleaved by diluted HF, but not by aqueous SbF3.
    Notes: Einfache stark hydrolyseempfindliche Methylchlorsilane und -silanole werden über raschenderweise von wäßrigen Antimontrifluoridlösungen fast ebenso gut fluoriert wie von der wasserfreien Verbindung. Methylchlordisiloxane werden zwar von verdünnter Flußsäure, dagegen nicht von wäßriger Antimontrifluoridlösung gespalten. Der Fluorierung der Si—Cl-Bindung geht offenbar die Hydrolyse zum Silanol voraus. Der Einfluß von Bortrifluorid-dihydrat auf die Fluorierung in wäßriger Antimontrifluoridlösung wird untersucht. Im Gegensatz zur Si—Cl- wird die C—Cl-Bindung von wäßriger Antimontrifluoridlösung nicht, von 20- bis 40proz. Flußsäure bei Raumtemperatur merklich fluoriert.
