Terpenoid resins

Water emissions from paper production softeners (BPA), other phenolic compounds (NPE, APE), other surfactants (LAS), biocides (benzothiazoler, dibromo compounds), wood extractions (terpenoids, resin acids) and more... 

Plant resins are lipid-soluble mixtures of volatile and nonvolatile terpenoid and/or phenolic secondary compounds that are usually secreted in specialized structures located either internally or on the surface of the plant. Although terpenoid resins constitute the majority of the resins produced and used, some other important resins are phenolic. Phenolic resin components, which occur on the surfaces of plant organs, have been used particularly in medicines [86].

The terpenoid resins commonly used as artists materials were colophony, Venice turpentine, mastic, dammar, copals and sandarac, and most of the scientific literature concerning the identification of Old Master varnishes and the study of their degradation focuses on these resins.

Amber is a fossilized form of terpenoid resin found in many parts of the world and used by people of many different cultures. The scientific analysis of amber began as early as the 16th century (1), and the analysis of its chemical composition has been going on for over 100 years (2). Because the material is nearly insoluble, modern analysis is primarily by infrared spectroscopy (3). Additional structural information about amber is now avail-... 

Amber (succinite). General term for fossilized terpenoid resins from the Tertiary period formed from resinous secretions of coniferous trees. They owe their hardness and poor solubility to the evaporation of volatile terpenes as well as to autoxidation and polymerization of resin acids and alcohols. The resin alcohols are mostly esterified with succinic acid. - [HS253090]... 

Sandarac. Light yellow conifer resin consisting of a mixture of terpenoid resin acids, especially pimaric (80%), callitrolic (10%), and sandaricinic acids (10%). S. is obtained from the bark of the North African sandarac cypress [Tetraclinis articulata (Callitris quadri-va/vis)].Mp. 135-140 °C, soluble in many organic solvents and turpentine oil. S. is used in the manufacture of special paints, polishes, putty, dental cement, and as a substitute for shellac (shellac wax).

Natural terpenoid resins are secreted by plants, for reasons that are still debated. However, it is documented that toxic resins discourage herbivores and insects from damaging plants. Terpene resins contain monocyclic (limonene and terpinolene) and bicyclic (a-pinene, P-pinene, sabinene) compounds (Figure 4.4). Some species also contain...
