Trimethylolpropane triacrylate Usage And Synthesis
DescriptionTrimethylolpropane triacrylate (TMPTA) is a multifunctional acrylie monomer. It reacts with propyleneimine to form polyfunctional aziridine. Sensitization was observed in a textile fabric printer. Patch tests were positive with the polyfunctional aziridine hardener, but were negative to TMPTA. TMPTA caused contact dermatitis in an optic-fiber manufacturing worker and was reported as a sensitizer in a floor top coat or in photopolymerizable inks.
Chemical PropertiesColorless viscid liquid
UsesTrimethylol propane triacrylate is a triacrylate for use in UV -curable lithographic inks, varnishes, artificial nails, wood finish solder, and etch resists in the electronics industry.
UsesTrimethylolpropane triacrylate has important properties like low volatility, resistance against weather, chemical, water and abrasion, and immediate curing property. The above mentioned properties prompted its use in the production of adhesives, plastics, sealant chemicals, paint additives, photosensitive chemicals, ink and toner. It finds application in alkyd coatings, dental polymers, compact discs, hardwood floors, concrete polymers, screen printing, elastomers, automobile headlamps, acrylics and plastic components for the medical industry.
DefinitionChEBI: Trimethylolpropane triacrylate is a carbonyl compound.
PreparationSynthesis of trimethylolpropane triacrylate: 2.44 kg of trimethylolpropane, 3.93 kg of acrylic acid, 0.5 kg of an acid ion exchanger (Lewatit 3333 of BAYER AG), 9 g of hydroquinone and 1.5 liters of petroleum ether (boiling range 60° to 70° C) were heated under a water separator, whilst stirring, in a 10 liter three-necked flask equipped with a stirrer, water separator and gas inlet tube. At the same time, a constant stream of air saturated with allyl alcohol was passed through the flask at a rate of 2 liters/hour. In total, 16 ml of allyl alcohol were introduced into the esterification mixture in this way. After 80 hours, the reaction mixture had an acid number of 32 and the boiling point had risen to 72° C. The petroleum ether was distilled off, remnants being removed by applying a vacuum of 0.2 mm Hg at a product temperature of 40° C. The esterification catalyst was separated off by filtration and was kept for further use. The trimethylolpropane triacrylate obtained in practically quantitative yield was pale yellowish and clear. The viscosity corresponded to a time of outflow of 20 seconds measured in a DIN cup 4 at 20° C. The product showed no change even on storage for 4 months at 60° C. When used in a UV light-curing printing ink which contained a photoinitiator, the product polymerised at high speed.
