Manufacturing Paper Sheets from Olive Wood by Soda, Sulphite and Kraft Pulping
Paper sheets from Iranian olive tree produced by soda, sulphite and kraft pulping.Then the influence of pulp beating on properties of paper sheets was studied. Kraft pulp exhibited the highest holocellulose/yield -cellulose/yield ratios and the sulphite pulp the soda pulp the highest lignin/yield ratio. Paper sheets from kraft with the breaking length 5851 m, stretch 4.61%, Burst index 4.48 KN/...
متن کاملBritain Kinetics of Thiamin Cleavage by Sulphite
Results are presented on the rate of thiamin cleavage by sulphite in aqueous solutions as affected by temperature (20-700), pH (2.5-7.0), and variation of the concentration of either thiamin (1-20,UM) or sulphite (10-5000,UM as sulphur dioxide). Plots ofthe logarithmn ofpercentage ofresidual thiamin against time were found to be linear and cleavage thus was first-order with respect to thiamin. ...
