✦ Synopsis

The aim of the present work was to study the fractionation of Eucalyptus globulus wood into pulp and by-products by alcohol-water pulping. Under the cooking conditions employed low lignin content pulp and a high yield of by-products were attained. The laboratory-scale alcohol and by-products recovery system studied consisted of three stages : black liquor ýashing, lignin precipitation from black liquor, and distillation of precipitation mother liquor. The mass balance for the process enabled the amount of pulp and by-products produced and the consumption of chemicals to be estimated.

Ab initio calculations using the STO-3G, 6-31G, and 6-31G \* \* basis sets are used to investigate charge distribution in tetracyclododecane alcohols. The calculated net atomic charges using fully optimized geometries indicate that certain carbon and hydrogen atoms in the proximity of a nonbonding o

Ab initio calculations using fully optimized geometries are used to generalize hyperconjugation effects in a representative series of eight polycyclic alcohols. The systems studied include tetra-, penta-and hexa-cyclic structures with varying degrees of tension, due to compression and stretching of
