Bacterial Degradation of Ecotoxic Dehydroabietic Acid

Kataliz v promyshlennosti, 2017
The possibility of biodegrading dehydroabietic acid (С20Н28О2, САS: 1740-19-8, abieta-8,11,13- trien-18-oic acid) (DAA), a toxic tricyclic diterpenoid, accumulated in the waste waters of the pulp and paper industry is studied using actinobacterial strain Dietzia maris IEGM 55Т. Cells of the strain Dietzia maris IEGM 55Т are shown to be resistant to DAA

Viscoelastic behavior of dehydroabietic acid

Journal of Rheology, 2002
The viscoelastic behavior of a rosin derivative, dehydroabietic acid, DHAA, has been determined with shear creep and recovery measurements at temperatures between 43 and 88 °C. The viscosity measurements extended up to 162 °C. The glass temperature Tg (0.2 °C/min cooling) was estimated to be 43.3 °C.

Preparation of dehydroabietic acid modified chitosan/wintergreen essential oil film and mandarin freshness preservation study.

Food Chemistry
In order to obtain an eco-friendly and multifunctional preservative film, dehydroabietic acid (DHA) modified chitosan (CS) containing wintergreen essential oil (CSDA-WEO) film was developed. CS grafted by DHA was able to increase the deformation capacity

Determination of the phase ratio of a dehydroabietic-acid-bonded silica-gel chromatographic stationary phase and its effect on separation thermodynamics.

Journal of Chromatography A
Rosin-based chromatographic columns are widely used for separation purposes, but, to date, their phase ratios (Φ) have been imprecisely measured. This affects the understanding of their separation mechanism and the calculation of related thermodynamic ...
