THE CONFERENCE PROCEEDINGS - IFEAT

faded out, which was equivalent to about USD 4.5 kg today, today’s China GT price of USD 2kg is still not expensive.3. Another factor is how many pine trees are used in pulping mills in China. The day when Chinastarts to produce a substantial quantity GT replacement material, such as tall oil rosin and CST,this will be the time for the traditional gum tapping to start phasing out.THE GT DERIVATIVES INDUSTRY IN CHINAGeneral Turpentine Derivative Industry ReviewTurpentine can be used for many different things, mainly as starting materials (Diag. 8) for terpenebased chemicals such as terpene resin, pine oil, borneol, camphor and aroma chemicals for F&Fformulations. The entire value chain of these products and downstream industries’ changes will havea significant impact on the turpentine market.Diag. 8 Turpentine Value ChainTurpentine as a feedstock of chemical synthesis began in late 19 th century after the elucidation ofterpene molecular structure provided by Otto Wallach who won the Nobel laureate for chemistry in1910. Camphor and terpineol are two terpene products that had been made at an early stage in theterpene industry. Amazingly they are still the most important products among the analogues after awhole century. Implementation of pyrolysis technology led the synthesis of terpene chemicals into anew era. Most of the important aroma chemicals, such as linalool, geraniol, citral, citronellol,dihydromyrcenol, iso E Super Rand menthol are made starting with alpha pinene or beta pinene. In themeantime, the petrochemical industry has penetrated everywhere in our lives. Terpene resins havealready lost a big market share through competition with hydrocarbon resin. The competition betweenterpene-based chemicals and petro-chemicals over major F&F ingredients has never stopped. Table 2illustrates competition between these two industries.97
