Additional Information
| Trimethylolpropane Alias: 1,1,1-Tris(hydroxymethyl)propane | 2,2-Dihydroxymethylbutanol | Trimethanolpropane | 2-Ethyl-2-(hydroxymethyl)-1,3-propanediol Abbreviation: TMP Foreign Name: Trimethylolpropane CAS No.: 77-99-6 EINECS No.: 201-074-9 Molecular Formula: C3H6O Molecular Weight: 58.079 Density: 1.116 g/ml Boiling Point: 49.0±0.0 °C Melting Point: 56-58 °C Flash Point: -32.0±15.3 °C Appearance: White flaky crystals Solubility: Soluble in water, lower alcohols, glycerol, N,N-dimethylformamide; partially soluble in ethyl acetate; slightly soluble in carbon tetrachloride; insoluble in aliphatic hydrocarbons, aromatic hydrocarbons, and chlorinated hydrocarbons. Uses: 1. Used as a raw material for synthetic resins, also for the synthesis of aviation lubricants, plasticizers, etc. 2. Used as a substitute for glycerol, also for the synthesis of drying oils. 3. Widely used in the production of polyester and polyurethane foams, as well as in alkyd coatings, synthetic lubricants, plasticizers, surfactants, and rosin esters. Also directly used as a textile auxiliary and thermal stabilizer for PVC resins. When used in alkyd resins, it improves the resin's firmness, color tone, weather resistance, chemical resistance, and sealing properties. 4. The molecule contains three hydroxymethyl groups at the A position, making it a neopentyl-structured triol. It enhances the resin's firmness, corrosion resistance, and sealing properties; exhibits excellent stability against hydrolysis, thermal decomposition, and oxidation; and features three hydroxyl groups with equal reactivity. 99999 |
