Oil shale phenols fraction REZOL

Phenols and phenol products

Rezol is a complex mixture of alkylresorcinols. It is obtained by distillation of the butyl acetate extract of oil shale retorting water and collecting the material condensing at >270oC.

REZOL could be used in the manufacture of

  • tires (essential component of an adhesive system) and rubber products; 
  • various adhesives, specially in high performance wood adhesives (wood bonding applications demanding room temperature cure together with structural integrity and waterproof characteristics),
  • resins;
  • gluey compounds;
  • plastics;
  • fire retardant plastic additives;light screening agents for the protection of plastics from exposure to ultraviolet light;
  • UV light stabilizers;
  • flame retardants;
  • agricultural chemicals;
  • fungicidal creams and lotions;
  • antioxidants;
  • dyes;
  • explosive primers;
  • polyurethane chain extenders;
  • synthetic tanning agents;
  • and numerous other organic chemical compounds.

In number of above mentioned applications REZOL could easily replace traditionally used synthetic resorcinols. REZOL’s higher activity (compared with the synthetic resorcinol) lowers the essential quantities resulting with significant cost-saving effects. 

The material has weak acid properties. Stable under ambient conditions. Reacts with oxidizing agents, alkalis. Contact with oxygen would result with oxidized product layer. Conditions of fire, explosion and chemical reactions can cause the release of toxic vapours or gases.

Samples in quantities up to 400 ml are available on request.
