    • The methylation of benzoylated glucose mercaptals 

      Wilkinson, I. A. (University of Canterbury. Chemistry, 1947)
      The central compound of the carbohydrates is glucose and it is around this substance that the chemistry of the carbohydrates and their molecular structure has been developed. The empirical formula was early established as ...
    • An apparatus for the purification of radon 

      Sutton, H. C. (University of Canterbury. Chemistry, 1947)
      As is well known, radium has been used for many years as a source of gamma radiation for therapeutic use. The method consists in placing needles of radium in suitable positions on and around the cancerous growth; dosage ...
    • The formation, control, and utilisation of the coastal sand dunes between the Waimakariri River and the Sumner Estuary. 

      Biggs, Leslie Ronald (University of Canterbury. Department of Geography, 1947)
    • αβγ-trimethyl-glutaconic acid 

      Jacobson, Paul R (University of Canterbury. Chemistry, 1947)
      Over a number of years many attempts have been made to synthesize αβγ-trimethyl-glutaconic acids. [Formula here]. No method has given very satisfactory results. In many cases the yields have been very poor and in no case ...

    • Foxton, its site and changing function. 

      Boniface, Herbert Garaway (University of Canterbury, 1947)
      To understand the present geographic character of Foxton, some knowledge of its history is essential, and it is therefore regrettable that no history of the town has ever been published. Many of the pioneer records have ...
    • An attempted synthesis of the cyanogenetic glucoside lotaustralin 

      Baker, A. F. H. (University of Canterbury. Chemistry, 1948)
      The term “glycoside” is a general term applied to compounds containing a group combined with a sugar residue through an ether linkage involving the reducing hydroxyl. The non-sugar portion is called agylcone. The sugar ...
    • Optically active alpha-beta-gamma-trimethyl-glutaconic acid 

      Nottingham, P. C. M. (University of Canterbury. Chemistry, 1948)
      The Mobility of the hydrogen atom in the three carbon system. So far as has been investigated, reaches its maximum in glutaconic acid where the three-carbon system is activated by two terminal keto-enol systems so that ...
    • The hydrolysis of glutamine 

      Penfold, B. R. (University of Canterbury. Chemistry, 1948)
      Glutamine, the Υ mono-amide of the glutamic acid was recognized and first isolated from beet juice by schulze and Bosshard in 1883. Since that time much investigation has been carried out into the nature of its role in ...
