Radiation-chemical decomposition of lignosulfonic acids in an aqueous medium with subsequent ozonolysis of degradation products

Radiation-chemical decomposition of lignosulfonic acids in an aqueous medium with subsequent ozonolysis of degradation products. Tupureine, A.; Aunins, E.; Rajavee, E. (Inst.Chemicals with cas numbers 8062-15-5 and 10028-15-6 also play role. Khim. Drev., Riga, USSR). Khim. Drev., (1), 44-6 (Russian) 1984. CODEN: KHDRDQ. DOCUMENT TYPE: Journal CA Section: 16 (Fermentation and Bioindustrial Chemistry) Section cross-reference(s): 8 The degrdn. of lignosulfonic acid [8062-15-5] and sulfite liquor in aq. soln. was enhanced by exposure to g-irradn. and O3. However, the combined effect of UV irradn. plus O3 was superior to that of g-irradn. plus O3. .

Ind., Polyurethane Div.: New York, N. Y. (English) 1983. CODEN: 50UXAW. DOCUMENT TYPE: Conference CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 38 The addn. of propylene oxide (I) [75-56-9] extender to Rubinate M (II) [9016-87-9] binder did not improve the bonding strength (BS) and H2O resistance of the resulting particleboard in comparison to II. The addn. of lignosulfonate (III) to I-II binder generally improved the BS, however, thickness swelling increased with increasing amts. of III. II-propylene carbonate (IV) [108-32-7] binder produced particleboards of equal properties at reduced levels of II; IV can be used to substitute for 30% of II with little sacrifice in board properties. Economical anal. indicated that II-IV binder systems () offer cost advantages over 7% phenolic resin or 9% urea resin binder systems. .
