Experimental study on rosin soap air-entraining agent;

This paper studies some factors such as the concentration of metallic ion in water,pH and addition of some surfactants which affects the stability of a rosin soap in alcohol/water solution and also tries to find out the way which can improve the stability of the rosin soap.

The reaction products of a new pine gum catalytic disproportionation were analyzed by gas chromatography/mass spectrometry(GC/MS) using HP-5MS flexible quartz capillary column.

Using a novel experimental apparatus with an improved agitator,a lumped kinetic model for the intermolecular hydrogen transfer reaction of pine gum over a Pd/C catalyst was investigated under nitrogen atmosphere.

Using turpentine from pine gum itself as solvent,catalytic disproportionations of P.
