An electrochemical process for the production of p-toluidene from p-nitro toluene
Part 6: Managing Open and Social EducationInternational audienceThere are many opportunities for social technologies to create wider and more valuable educational communities. This paper presents an analysis of a Government initiative to create educational communities around schools in Victoria, Australia using social networking systems. The analysis, comparing several systems, shows that a number of factors, including interpretation of reactions by actors are crucial to the success of applications of social technologies in an educational setting
Improvements in and or relating to the electrolytic preparatlon of manganic sulphate.
The oxidation of manganese sulphate~ both
chemically and electrolytically in presence of sulphuric
acid to obtaili. different oxidation products of manganese
is well known. The use of maI}.ganoussulphate
as a "carrier" in the electrolytic oxidation of toluene
to benzaldehyde has been reported Dy several erurlier
workers. The manganous sulphate used in such experiments
was in catalytic quantities. The manganic
sulphate produced electrolytically from it was repo.rted
to bring about the oxidation of toluene and the
manganous sulphate formed in the reaction was ~eoxidised
in the cell. Most of the work reported eaJrher
was confined to studies of electrolytes containing
man,gahese sulphate only in' solution~ Since it ill
known that the solubility of manganous sulphatl~ is
considerably reduced with increasing strength of
sulphliric acid, it was considered useful to investigate
systems in wl1ich the limitations arising from this
could be overcome
