Trimethylol propane 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 trimethylol propane is used for the production of dyestuffs, pigments, paints and silicone products. LANXESS offers trimethylol propane 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:
Trimethylol propane is characterised by a high stability against light and environmental influences.
The structure of trimethylol propane leads to a balanced ratio of stability and flexibility in the products.
Chemical and physical properties: Trimethylol propane is a white solid at room temperature. Above 59 °C trimethylol propane melts to a colorless liquid. Trimethylol propane is well soluble in both water and organic solvents.
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.
