Description

The alkali lignings have been precipitated with the anorganic acids (sulphuric acid and hydrochloric acid) and with the some organic acids (formic, acetic, lactic, oxalic, tartaric, citric acid), as well as the lignosulphonic acid with caustic soda. On these cases, the effects of the hydrogen-ion concentrations and the salting-out effects of the some salts (Ca<Cl>_2, <Na>_2SO_4, NaCl, Pb<(<CH_3CO)>_2・3H_2O) were researched. On the reactivity of these alkali lignins with phenol and anilin will be reported in the following reports.
