The structure of the nonaaquayttrium (III) bromate, [Y(H2O)9](BrO3)3, at low temperature (100 K) has been studied by means of single-crystal X-ray diffraction. Crystallography shows a hexagonal unit cell, space group P63/mmc (No. 194) with Z = 2, a = b = 11.7104(11) Å, c = 6.6259(5) Å and V = 786.90(12) Å3 at 100 K. The hydra...

A number of methods are available for the quantitative estimation of cellulose in plant materials and have been reviewed by Doree (1933). Almost all of them are based upon the original procedure of Cross & Bevan (1903), who used chlorine gas for the removal of lignin as 'lignone chloride' followed by hot sodium sulphite extraction. Since then Jenkins (1930) and Norman & Jenkins (1933) have prop...
