CHEMICAL PROCESS PRODUCTS 



To this point only physical processing of the forest 

 resource has been given consideration. The one exception 

 is the production of pulp and paper which can be considered 

 as involving both physical and chemical processes. 



At the present time there are three chemical derivatives 

 of wood being commercially produced in the state. Tall oil 

 used in detergent, emulsions, and as a lubricating medium in 

 paints, and turpentine are drawn off as a by-product of the 

 pulp and paper industry. Calactan, a water soluble deriva- 

 tive of western larch, used in printers ink and as a binder 

 in pharmaceuticals, is also a by-product of the state's timber 

 industry manufactured under the trade name of STRactan, 



Also a study is being made of chemical additives for 

 the purpose of modification of wood to improve or supplement 

 the finer qualities and practical features of this structural 

 material by treatment or combination with some chemicals. 

 Application of various forms of paints and coatings to wood and 

 wood products has found general acceptance; treatment with 

 flame retardants and preservatives is practiced commercially 

 for a variety of products; dimensional stabilization of wood 

 has been extensively investigated and found occasional 

 application with specialty products; plastic impregnation or
