Examples

  • The process of V.B. Drewson (D.R.P. 67,889) consists in heating with lime under pressure, yielding calcium monosulphite (with sulphate and the lignone complex in insoluble form).

    Researches on Cellulose 1895-1900 C. F. Cross

  • The lignone chloride is removed by sodium sulphite solution, and the residue is a _cellulose benzoate_.

  • In reacting with chloride it shows the presence of unsaturated groups, similar to the lignone of the woods.

    Researches on Cellulose 1895-1900 C. F. Cross

  • This author considers that beyond the empirical facts established by the above named [10] very little is yet known in regard to the constitution of the lignone complex.

  • It will be thus seen that there are no changes of any essential kind in the chemical composition of the bast fibre throughout the life-history of the plant, confirming the conclusion that the 'incrustation' view of lignification is consistent only with the structural features of the changes, and so far as it has assumed the gradual overlaying of a cellulose fibre with the lignone substance it is not in accordance with the facts.

  • The loss of weight due to the elimination of the lignone was 12.7 p. ct.

    Researches on Cellulose 1895-1900 C. F. Cross

  • The jute acetate showed the normal reaction with chlorine, and the lignone chloride was dissolved by treatment with sodium sulphite solution.

    Researches on Cellulose 1895-1900 C. F. Cross

  • The lignone group as it exists in the lignocellulose has no free OH groups, and probably no free aldehydic groups such as would react with the anhydride.

    Researches on Cellulose 1895-1900 C. F. Cross

  • Under the conditions adopted in dissolving away the chlorinated lignone the original non-benzoated lignocellulose would have yielded a cellulose giving 6 to 7 p.ct. furfural.

    Researches on Cellulose 1895-1900 C. F. Cross

  • The variations are due to the varying conditions of the digestion of the wood and to corresponding degrees of sulphonation of the original lignone group.
