| 应用领域 | Uses: Used to make varnishes、drying oils、and polyesters for polyurethane foams、alkyd surface coatings、lubricants、and hydraulic fluids、Also used as a heat stabilizer for polyvinyl chloride resins、[HSDB]、Painting (Solvents) [Category: Paint]、Plastic Composites Manufacturing [Category: Industry]、Conditioning agent、mfr of varnishes、alkyd and polyester resins、synthetic drying oils、Used in the manufacture of alkyd surface coatings and polyester resins (polyurethane foams). Heat stabilizer for polyvinyl chloride resins.、Polyethers are used in ethylene vinyl acetate and polyurethane adhesives.、CHEM INT FOR POLYESTERS FOR POLYURETHANE FOAMS、For more Uses (Complete) data for 1、1、1-TRIS(HYDROXYMETHYL)ETHANE (9 total)、please visit the HSDB record page.、Industry Uses: Surface modifier、Intermediate、Pigment、Surfactant (surface active agent)、Binder、Consumer Uses: Pigment、Methods of Manufacturing: Trimethylolethane is made by aldol condensation of propionaldehyde with formaldehyde、followed by reaction of the intermediate 2、2-bis(hydroxymethyl)propanal with excess formaldehyde in the presence of sodium hydroxide or lime as basic component. The resulting aqueous solution is freed from excess formaldehyde by distillation under pressure and further concentrated. The formate byproduct can be separated by extracting the trimethylolethane from the residue with organic solvents such as 2-propanol or by almost complete removal of the water and dissolving the trimethylolethane in acetone or methanol.、U.S. Production: 2023: 1、000、000 - <2、500、000 lb、2022: 2、000 - <4、2021: 2、2020: 2、(1979) 4.76X10+9 GRAMS (ESTIMATE)、(1981) 4.76X10+9 GRAMS (ESTIMATE)、Production volumes for non-confidential chemicals reported under the Inventory Update Rule. [Table#5275]、1-Tris(hydroxymethyl)ethane is listed as a High Production Volume (HPV) chemical (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S. in >1 million pounds in 1990 and、or 1994. The HPV list is based on the 1990 Inventory Update Rule.
