SummaryThe dephosphorylation of β-casein, type A1, by dilute aqueous solutions of sodium hydroxide has been studied. It has been found that the mechanism whereby inorganic phosphate is liberated by the action of alkali is one of β-elimination from O-phosphoserine residues which are themselves converted initially to dehydroalanyl residues.

Abstract The authors investigated the adhesion of rubber compounds containing nickel blanched alkyl carboxylate to surface treated magnesium alloys during curing. Ni i-octylate and Ni i-stearate were used as nickel branched alkyl carboxylate. Rubbers used in the study did not adhere at all to magnesium alloys, such as AZ91, AZ31, AZ 21, and M1 washed with acetone; not even in the presence of Ni i-octylate. Among numerous treating solutions, only sodium hydroxide aqueous solution was effective for adhesion of rubber to magnesium alloys. Adhesion of rubber to magnesium alloy AZ31 treated in 0.5M- sodium hydroxide aqueous solution for 10 min at 80 °C yielded high peel strength and a 100% rubber coverage. Peel strength and a 100% rubber coverage varied with the concentration of additives, such as curing accelerators, sulfur, zinc oxide and Ni-type adhesive accelerators. Ni branched alkyl carboxylates such as Ni i-octylate and Ni i-stearate were effective for accelerating the adhesion of rubber to magnesium alloys treated in sodium hydroxide aqueous solutions during curing. The authors postulate that Ni branched alkyl carboxylate acts to yield interface bonds between magnesium alloys and rubber or Ni-S-rubber linkage.

This work investigated the feasibility of Quercus mongolica sawdust pretreated by an ionic liquid-water mixture as a biosorbent for Cu (II) removal from aqueous solutions. Maximum Cu (II) biosorption of 32.6 mg/g is obtained at initial pH 4.3 using sawdust pretreated by a 1-butyl-3-methylimidazolium chloride ([C4miCl)-water mixture (IL content 60%) at 90oC, which is higher than that of unpretreated sawdust (23.0 mg/g, initial pH 6.1). The proposed method is effective in enhancing adsorption capacity of the biomass in comparison to the conventional methods using sulfur acid or sodium hydroxide solutions.

Acetone Concentration

Increased acetone concentration in aqueous solutions of sodium hydroxide lowers the specific conductivity to a marked degree. This cannot be satisfactorily explained by viscosity change only, but is probably accounted for by a combination of changes in both viscosity and dielectric properties of the solutions. An empirical equation is suggested.
