“…Upon storage, either at room temperature or at −20°C, the amino ester completely rearranges to 3. N,N-[Bis-(2-hydroxyethyl)]-dehydroabietic acid amide (5). Dehydroabietic acid methyl ester (1.57 g, 5 mmol) and N,N-diethanolamine (2.63 g, 25 mmol) were charged to a 10-mL round-bottomed flask equipped with a mechanical stirrer.…”

The syntheses of derivatives of dehydroabietic acid suitable for further manipulation into surfactants are presented. The compounds are produced at very high yields and purity. They contain several different functional groups, e.g., carboxylic acid, amine, ester, alcohol, and an aromatic group. The functional groups are useful as the linking unit to the hydrophilic part in synthesizing surfactants.

“…Rosin can be disproportionated to di-and dehydroabietic acid (4), thereby enhancing its resistance to oxidation. From disproportionated rosin, pure dehydroabietic acid can be isolated by crystallization of the 2-aminoethanol salt (5)(6)(7).…”

ABSTRACT:In this article, the influence of rosin-type clarifying agent Nu-(K ϩ Na) and low density polyethylene (LDPE) on the crystallization process of polypropylene (PP) from the melt state was studied by differential scanning calorimeter and polarization microscope, and the effect of rosin-type clarifying agent Nu-(K ϩ Na) on the compatibility of PP and LDPE was also investigated by dynamic mechanical analysis and scanning electron microscope. It was found that Nu-(K ϩ Na) decreased the fold surface energy and promoted the nucleation and crystallization of PP. With the cooperation of LDPE and Nu-(K ϩ Na) in PP, the chain fold free energy of PP was further decreased substantially, the crystallization rate of PP was increased more markedly, and the spherulites of PP became much smaller and dispersed more uniformly. At the same time, Nu-(K ϩ Na) improved the compatibility of PP and LDPE, and the LDPE was dispersed in PP more uniformly. Thus, the light scattering originating from the spherulites of PP and the LDPE disperse phase was reduced to great extent, and the transparency of PP was improved evidently. © 2005 Wiley Periodicals, Inc.
