Report from the Koninklijke/Shell Laboratorium, Amsterdam. 

H. Berger (Koninklijke/Shell Laboratorium, Amsterdam) Concerning the effect of cyanides on metal catalysis (deactivation and formation of oxygenated products), what are your arguments against the explanation that the metal ion becomes completely inactive, while the products arise from a mechanism analogous to that proposed by Berger [Rec. Trav. Chim. 82, 733 (1963)] for the oxidation in tert-butyl alcohol with excess mercaptan relative to base, Did you check that no hydrolysis of disulfide occurs in the presence of cyanide ...

B. D. McNicol (Koninklijke/Shell Laboratorium, Amsterdam, Netherlands) With reference to Figure 1 of your paper regarding the spin concentration of positive anthracene ions, you state that rehydration results in a large decrease in spin concentration. This is certainly not apparent in the figure. Also, were no measurements made on rehydrated samples which had been activated above 550°C This would shed some light on the reason for the decrease in spin concentration observed above 550°C. In the absence of x-ray or other evidence, this decrease may not be due to structure collapse. 

The authors wish to thank Ir J. E. Naber of the Koninklijke/Shell-Laboratorium Amsterdam for critically reviewing the manuscript.

The various integrated signal intensities representing the supported compounds relative to the one representing the support can be translated quantitatively into layer thicknesses (or particle sizes) and coverages of the materials on the carrier.

Brian D. McNicol (Koninklijke/Shell Laboratorium, Amsterdam, Netherlands) With respect to your comment on the formation of Ag° within the cavities by a photosensitized redox reaction, if the Ag° atoms are monatomically dispersed, then they could be identified by electron spin resonance. Ag°, of course, is paramagnetic. 

The results described in this book could only be obtained by the expertise and the cooperation of many members of the different skillgroups at the Koninklijke Shell Laboratorium in Amsterdam (KSLA). The still unique possibilities of this laboratory are mentioned with pleasure. 

The table below lists the various TA techniques following the notation of the ICTA (International Committee for Thermal Analysis) nomenclature committee. The three "classic" TA techniques are DSC, TGA and TMA of which DSC is still the "workhorse". TA is also covering, however, a substantial number of other techniques and applications and several of these techniques are described in this book. This book is not a comprehensive textbook about TA but more a survey of the author s work during many years, at the Koninklijke Shell Laboratorium in Amsterdam. It describes in six chapters the use of the various TA techniques (printed in bold in the table) for specific problems, illustrating the versatility of TA. A technical description is only given for equipment of own design. 

The catalyst system developed at the Koninklijke/Shell Laboratorium in Amsterdam, The Netherlands, for the RIM polymerization of DCPD is WCV 2,6-diisopropylphenol (1/2) with R3SnH as cocatalyst. Both components are soluble in DCPD and have a long shelf-life. This catalyst system has the advantage of being able to polymerize DCPD of technical quality (van Deursen 1989).
