Example text

Freudenberg (74) apparently set forth the first formulation of the structure of cellulose in 1928. In 1933, Freudenberg (100) published a book with a chapter on lignin. Herein he suggested that lignin was a high polymer formed by dehydrogenation of coniferyl alcohol type monomers as suggested by Erdtman. He felt that lignin was a heteropolymer linked by ether and carbon-carbon bonds. Furthermore he felt that there were three or four types of structural units as happens with amino acid in proteins Around the end of the 1940's coniferyl alcohol became easily available through the reduction of ethyl ferulate by L1AIH4 (271).

Pearl (208) in 1949 secured similar evidence from the products of metal oxide oxidation of lignosulfonates. In 1935, King, Hibbert and Brauns (119) reported on organosolv lignins formed through methanolysis and ethanolysis. The soluble products of these reactions, Hibbert's ketones, were described in a series of papers with Cramer and Hunter (148), West (171), McGregor and Evans (176) and several others. These ketones were phenylpropane type molecules obtained in about 10% yield when wood was refluxed in acidic 3% methanol/ethanol solution.

In 1980, kraft pulping was interpreted in chemical terms by Gierer (452) as a competition between alkali-promoted degradation and condensation reactions. Cleavage of the various types of lignin bonds was attributed to three phases of kraft pulping. Similarities in the degradation mechanisms of lignins and carbohydrates were noted. Based on the results from extensive model studies, Gierer (486,487) in 1985 divided the chemical reactions involved in pulping and bleaching into nucleophilic and electrophilic categories.
