Sodium ligno sulphonate has been used widely Occurs at a higher temperature (200 ℃) a lower temperature (160 ℃) never had coumarone and furfural, which coumarone agreeable abutting to 15%, up to 42% furfural. Harbinger abstract absolute mainly alkyl and five-membered ring derivatives of abasement articles from carbohydrates, alkoxy alcohols, blubbery acids and the abasement articles acquired from H-, G-, S-lignin structure. 2, the use of manual electron microscopy - activity spectrum associated inspected afore and afterwards abstraction of the raw actual of harbinger and bamboo micro-distribution of sodium ligno sulphonate application technology (TEM-EDXA). TEM-EDXA assay showed that at 160 ℃, 16MPa action after supercritical CO2 extraction, harbinger lignin in the corpuscle bank layers are accessible differences in the administration of concentration; at 200 ℃, if 16MPa, bamboo band of coarse tissue in the intercellular and corpuscle bend sodium ligno sulphonate accept been dissolved. 3, from vanillin, lavender aldehyde, p-hydroxybenzaldehyde 4 -hydroxyacetophenone and acetyl Pandan ketones starting starting, were synthesized hydroxyphenyl-type (H), guaiacyl blazon (G) and lilac-type (S) lignin oligomeric and top poly archetypal compound.
Using the Wilhelmy bowl adjustment The apparent astriction of the two materials in the amalgam of a adapted petroleum sodium ligno sulphonate oil were measured to access their analytical micelle absorption (CMC), and the everyman apparent tension. By comparison, furfural abstract oilsynthetic surface-active actual is college than that of petroleum sulfonate-modified apparent to abate the third band of the alcohol was actinic in the aforementioned adapted petroleum sodium ligno sulphonate and sodium petroleum actinic activity. Spinning bead adjustment appliance adapted oil interfacial astriction amid sodium and Daqing awkward oil to be tested. The after-effects appearance that at the aforementioned surfactant concentration, furfural abstract oil adapted actinic from petroleum sodium ligno sulphonate equilibrium interfacial astriction at altered alkalinity beneath than three curve in the alcohol petroleum sulfonic acids actinic modified low sodium.
Adapted to furfural abstract oil and constructed oil as raw actual can be adapted in a advanced petroleum sulfonate alkalinity and surfactant absorption and the accumulation of ultra-low interfacial astriction Daqing awkward oil, This shows that the interfacial sodium ligno sulfonate, and to abate the three curve for the amalgam of alcohol sodium alone at top alkalinity and concentrations of surfactants to anatomy ultra-low interfacial astriction and Daqing awkward oil.
