15625-89-5 Usage
Description
Trimethylolpropane 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.

Uses
Different sources of media describe the Uses of 15625-89-5 differently. You can refer to the following data:
1. Trimethylol 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.
2. Trimethylolpropane 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.
Preparation
Synthesis 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.Literature source US04059721

Check Digit Verification of cas no
The CAS Registry Mumber 15625-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,6,2 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 15625-89:
(7*1)+(6*5)+(5*6)+(4*2)+(3*5)+(2*8)+(1*9)=115
115 % 10 = 5
So 15625-89-5 is a valid CAS Registry Number.

Paragraph 0021-0042, (2020/07/12)
The invention provides a synthesis method of trimethylolpropane triacrylate. The synthesis method comprises the following steps: step 1, sequentially adding trimethylolpropane, acryloyl chloride, triethylamine, hydroquinone and p-hydroxyanisole into a reaction kettle in proportion; controlling the reaction system to perform stirring reaction at the temperature of 40-60 DEG C for 2-3 hours; and step 2, after the reaction is completed, filtering the reaction solution to remove insoluble solid impurities, washing with water, and drying to obtain the product. Acryloyl chloride is used as a raw material to replace acrylic acid, and the reaction activity of acryloyl chloride is higher than that of acrylic acid so that the reaction temperature is reduced in the synthesis process, and the reactiontime is shortened; acryloyl chloride participates in the reaction, no water is generated, the use of a water-carrying agent methylbenzene or cyclohexane is avoided, the production cost is reduced, and the pollution of the organic solvent to the environment is also avoided.
Chemoselective Transesterification of Acrylate Derivatives for Functionalized Monomer Synthesis Using a Hard Zinc Alkoxide Generation Strategy
Nakatake, Daiki,Yazaki, Ryo,Ohshima, Takashi
supporting information, p. 3696 - 3699 (2016/08/20)
A new practical method for the synthesis of functionalized acrylate derivatives with the view to prepare functional polymers was explored. Hard zinc alkoxide generation enabled the highly chemoselective transesterification of acrylate derivatives over the undesired conjugate addition, which caused polymerization. The combined use of the catalytic zinc cluster Zn4(OCOCF3)6O and 4-(dimethylamino)pyridine delivered various functionalized acrylate derivatives through the transesterification of commercially available methyl acrylate derivatives with functionalized alcohols under mild conditions.
