    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

Rates of saponification ofα-chlorotoluene,αα-dichlorotoluene andα,α,αtrichlorotoluene and of their ortho, meta, and para isomers of halogen, nitro methyl and carboxylic derivatives in neutral, alkaline or acid medium were measured. The velocity of the hydrolysis in the different ranges of pH could be correlated with the effect of substituents present in the aromatic compounds and with the character of the catalysts involved in the reactions. The results obtained when saponifying in basic medium could be reasonably

explained by the 'alternating polarity effect' (valid at that time) and by assuming a general electron shift in the direction of the negative substituent.
