What is trimethylolpropane used for?
TMP is used in saturated polyesters for coil coatings, alkyds for paints, polyurethanes for coatings and elastomers, acrylic acid esters for radiation curing, esters for synthetic lubricants, rosin esters and for surface treatment of pigments.
Is trimethylolpropane an alcohol?
Trimethylolpropane (TMP) is an alcohol and is being produced by the reaction of Formaldehyde with n-Butyraldehyde. Trimethylolpropane is an triol.
Is trimethylolpropane hazardous?
* Trimethylolpropane Phosphite is on the Hazardous Substance List because it is cited by EPA.
What is TMP in chemicals?
Trimethylolpropane (TMP) is the organic compound with the formula CH3CH2C(CH2OH)3. This colourless to white solid with a faint odor is a triol. Containing three hydroxy functional groups, TMP is a widely used building block in the polymer industry.
Is trimethylolpropane a polyol?
Poly-G® 30-64T polyol is propoxylated trimethylolpropane (TMP) containing all secondary hydroxyl groups. Its primary use is in Elastomer, Coating,and Adhesive applications. Poly-G 30-64T polyol has an average molecular weight of 2500. It is a stable, practically colorless liquid that is neither volatile nor corrosive.
Is trimethylolpropane soluble in water?
Chemical Properties Trimethylolpropane is a Colorless, hygroscopic crystals. Soluble in water and alcohol.
How TMP is produced?
TMP (thermomechanical) pulping processes provide excellent strength related properties of paper at a high production capacity. TMP process can consist of single stage, two or three refiners in a series in one production line supplying paper machine, and the TMP pulp is dewatered and stored before papermaking.
Is glycol a polyol?
The term polyol is used for polyether polyols and polyester polyols. A typical example is polyethylene oxide or polyethylene glycol (PEG) and polypropylene glycol (PPG). Polyols are reacted with diisocyanates to produce polyurethanes. The term “polyol” is also attributed to other molecules containing hydroxyl groups.

Is stevia a polyol?
Due to polyols reduced sweetness compared to table sugar, they are often blended with high-intensity sweeteners, such as stevia, monk fruit, and sucralose.
Is PVA a polyol?
The term “polyol” is also attributed to other molecules containing hydroxyl groups. For instance, polyvinyl alcohol is (CH2CHOH)n with n hydroxyl groups where n can be in the thousands. Cellulose is a polymer with many hydroxyl groups, but it is not referred to as a polyol.
Why 2 ethyl butane is not an isomer of hexane?
When identifying an isomer name, firstly we need to observe the longest carbon chain in a molecular structure. In 2-ethylbutane, the longest carbon chain is 5C (pentane), therefore it should be read as 3-methylpentane instead of “2-ethylbutane”. Number of isomers of hexane.
What is the formula for trimethylolpropane triol?
Trimethylolpropane (TMP) is the organic compound with the formula CH 3 CH 2 C (CH 2 OH) 3. This colourless to white solid with a faint odor is a triol. Containing three hydroxy functional groups, TMP is a widely used building block in the polymer industry.
What are the main uses of trimethylolpropane?
TMP is mainly consumed as a precursor to alkyd resins. Otherwise, acrylated and alkoxylated TMP’s are used as multifunctional monomers to produce various coatings, Ethoxylated and propoxylated TMP, derived condensation of from TMP and the epoxides, are used for production of flexible polyurethanes.
How is trimethylolpropane ( TMP ) produced each year?
TMP is produced via a two step process, starting with the condensation of butanal with formaldehyde : The second step entails a Cannizaro reaction : Approximately 200,000,000 kg are produced annually in this way.
What is the molecular formula for oxetane oxide?
Oxetane, or 1,3-propylene oxide, is an heterocyclic organic compound with the molecular formula C 3H 6O, having a four-membered ring with three carbon atoms and one oxygen atom.
