    Description / Table of Contents: Di-and Polyamino Sugars, XXI. Synthesis of Derivatives of 2,4-Diamino-2,3,4-trideoxy-D-ribo-hexoseStarting with D-glucose the title compound has been synthesized as its di-N-acetyl. -trifluoroacetyl and N,N′-bis(2,4-dinitrophenyl) derivative. The free sugar could not be obtained in a pure state.
    Notes: Die Titelverbindung wurde, ausgehend von D-Glucose, in Form ihres Di-N-acetyl-, -trifluoracetyl- und ihres N,N′-Bis(2,4-dinitrophenyl)-Derivates erhalten. Reindarstellung des freien Zuckers gelang nicht.

    Description / Table of Contents: Heterocyclic Seven-membered Ring Compounds, XVI. Synthesis of 3,5-Substituted 4-Phenyl-1-benzothiepins4-Phenyl-1-benzothiepins 7 and 8 are synthesized starting from their 5-methoxy-2,3-dihydro-precursor 2; using the 2,5-dihydro-intermediate 12 yields the 4-phenyl-1-benzothiepins 13 and 14. The 1-benzothiepin 17 can be obtained from the diketone 1 directly. The 3-cyano-substituted compound 22 is prepared from its 2,5-dihydro-precursor 21. Some ring-contraction and ring-cleavage reactions of the heterocyclic seven-membered ring-system are described.
    Notes: Die 5-Methoxy-2,3-dihydro-Vorstufe 2 wird in die 4-Phenyl-1-benzothiepine 7 und 8 übergeführt; aus der 2,5-Dihydro-Vorstufe 12 werden die 4-Phenyl-1-benzothiepine 13 und 14 dargestellt. Das 1-Benzothiepin 17 wird direkt aus dem Siebenring-Diketon 1 erhalten. Das 3-cyan-substituierte 1-Benzothiepin 22 erhält man aus der 2,5-Dihydro-Vorstufe 21. Es werden einige Ringverengungsbzw. Ringspaltungsreaktionen des heterocyclischen Siebenring-Systems beschrieben.

    Heat transfer during fluidized-bed coating (1975)

    Notes: A fully implicit numerical method for linear parabolic free boundary problems with coupled and integral boundary conditions is described. The partial differential equation and the boundary conditions are time discretized with the method of lines. An auxiliary function is introduced to remove the coupled and integral boundary conditions from the resulting free boundary problem for ordinary differential equations. Once separated boundary conditions are obtained, invariant imbedding is used to solve the free boundary problem numerically. The method is illustrated by solving the heat transfer equations for the fluidized-bed coating of a thin-walled cylinder.
