What reading level is Researches On Cellulose Iv 1910 1921 volume Iv of the Series Cross And Bev book?
To quickly assess the difficulty of the text, read a short excerpt:
' This complex, which is isolated by the Cross and Bevan chlorination treatment in the form of 'lignone chloride, ' C 19 H 18 C1 4 O 9 (in the case of jute), can now be obtained very simply by the use of 42 per cent, hydrochloric acid, following the observations of Willstatter on the action of this acid on the cellulose portion of lignocelluloses.
To what extent the product thus prepared resembles the original lignin constituent of the wood-complex is uncertain, but it must depend on the relati...on of lignin to the complex as a whole. We do not recall any recent researches dealing with this problem. The theory of Wislicenius (1910) that the lignin and the carbohydrates of the lignocellulose are united on the basis of the force of surface tension is a very valuable one, in agreement with the structural and chemical conception neces- sarily to be assumed for such complexes. A union of this order is more probable than a purely chemical one, though the intermediate view that union takes place between carbohydrate and lignin in virtue of the supplementary valencies of the oxygen atoms of hydroxyl groups deserves consideration.
