A method for the synthesis of N-alkylpiperidynes.

June 27, 1990
Author(s)
Anzor I. Mikaia, George A. Kliger, OA Lesik, EV Marchevskaya, Vladimir G. Zaikin, Leonid S. Glebov, Sergai Loktev
Reaction gas chromatography–mass spectrometry is applied to establish optimal conditions for the synthesis of N-alkylpiperidynes. Further optimization of the reaction was carried out in a pilot plant.

Viscometer for low frequency, low shear rate measurements

August 1, 1986
Author(s)
Robert F. Berg, Michael R. Moldover
We describe a torsion-oscillator viscometer whose low frequency ( 0.5 Hz) and very low shear rate (0.05 s-1) are required for measurements of shear sensitive fluids such as microemulsions, polymer melts and solutions gels, and liquid mixtures near critical
