For many years published research of both American and European laboratories has disclosed a wide variety of valuable products that may be derived from hydroabietyl alcohol. Now, Hercules announces the first commercial production of this interesting chemical material. Hercules hydroabietyl alcohol is the most resistant to discoloration and degradation by light or air of all rosin derivatives. It is a viscous liquid at room temperature; is colorless, tacky, and not miscible with water, in contrast to more commonly used alcohols. Like other high molecular weight primary alcohols, hydroabietyl alcohol is subject to esterification with both organic and inorganic acids, and etherification. It is miscible with alcohols, ketones, esters, ethers, hydrocarbons, and chlorinated hydrocarbons, and is compatible with many film-formers and resins used in protective coatings, adhesives, and other products. Research indicates that this new rosin alcohol may be reacted to yield resins, foamers, detergents, wetting agents, emulsifying agents, plasticizers, corrosion inhibitors, antioxidants, parasiticides, bactericides, and compounds highly stable to ultra-violet light. It may be used without further chemical reaction as a modifier for chlorinated rubber, polyamides, hydrogenated oils,
textile sizes, rubber compositions, and essential oil vehicles. Never before has industry had the opportunity to investigate the potentials of this low-cost alcohol. Now, with commercial production in full swing at a new Hercules plant, hydroabietyl alcohol is immediately available to industry in quantity.
