Polyols and Oxidation Products
Trimethylolpropane is a trifunctional alcohol with a wide spectrum of applications in the chemical industry, e.g. for the synthesis of alkyd and polyester resins, synthetic lubricants, PU-foams and lacquers or glues and adhesives. Furthermore trimethylolpropane is used for the production of dyestuffs, pigments, paints and silicone products. LANXESS offers trimethylolpropane from its production sites in Germany and China as flakes as well as liquid in road tankers, tank containers and drums.
Advantages of trimethyl propane as intermediate:
• Trimethylolpropane is characterised by a high stability against light and environmental influences.
• The structure of trimethylolpropane leads to a balanced ratio of stability and flexibility in the products.
Chemical and physical properties:
Trimethylolpropane is a white solid at room temperature. Above 59 °C trimethylolpropane melts to a colorless liquid. Trimethylolpropane is well soluble in both water and organic solvents.
1,6-Hexanediol is an organic intermediate with a wide spectrum of uses in the chemical industry. Important applications are in the plastics industry, where 1,6-hexanediol is used as additive or hardener and cross linking agent for the synthesis of polyesters, high temperature polymers, polyacrylates or polyurethanes. The production of glues and adhesives, lacquers, synthetic lubricants, textile coatings, surfactants and softening agents, dyestuffs, printing inks, and pharmaceutical active ingredients are other important applications of 1,6-hexanediol. Typical reactions of 1,6-hexanediol are such with mono or dicarbonic acids, diisocyanates, carbonates or phosgene. LANXESS offers 1,6-hexanediol from its production site at Krefeld-Uerdingen as solidified melt as well as liquid in road tankers, tank containers and drums.
Advantages of 1,6-hexanediol as intermediate:
• Compared to other diols, the primary positions of the hydroxyl groups in 1,6-hexanediol lead to an acceleration of the polymerization.
• 1,6-Hexanediol provides hardness and flexibility to plastics and effects enhanced adhesion in glues and adhesives.
• Dyestuffs and coatings based on 1,6-hexanediol are characterised by an improved light fastness and a very small susceptibility to hydrolysis.
Chemical and physical properties:
At room temperature, 1,6-hexanediol is a white to slightly yellow solid. Above 42 °C it melts to a colourless to slightly yellow liquid. 1,6-Hexanediol has an unlimited miscibility with water and common organic solvents. 1,6-Hexanediol is characterised by very low toxicity and a high ignition temperature (335 °C), which allows a convenient handling of the material.

Maleic anhyhydride
Maleic anhydride is a highly reactive chemical intermediate with present and potential uses in practically every field of industrial chemistry. It is essential to the production of a multitude of resins and plastics, agricultural and industrial chemicals, petroleum additives, paper sizing, water treatment chemicals, epoxy curing agents, artificial sweeteners, flavor enhancers, hair sprays, pharmaceuticals and copolymers. Its biggest single use is in the manufacture of unsaturated polyester resins. LANXESS offers molten maleic anhydride from its production site in Baytown, TX in tank trucks, rail cars, and bulk isocontainers .
Advantages of maleic anhydride as intermediate:
Chemical conversions of maleic anhydride are a result of its structure. An acid anhydride group, a reactive double bond and the easy conversion of many of its derivatives into isomeric derivatives of fumaric acid make it a multifaceted resin-former and organic reactant for a variety of chemical transformations.
Chemical and physical properties:
Maleic anhydride is a solid at room temperature. Above 52.9 °C it becomes a clear, colorless, low viscosity liquid. Maleic anhydride is soluble in water forming maleic acid.
