Trimethylolpropane triacrylate Specification

The IUPAC name of Trimethylolpropane triacrylate is 2,2-bis(prop-2-enoyloxymethyl)butyl prop-2-enoate . With the CAS registry number 15625-89-5, it is also named as 1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, triacrylate ; 2-Ethyl-2-(hydroxymethyl)-1,3-propanediol triacrylate ; Acrylic acid, 1,1,1-(trihydroxymethyl)propane triester ; NK Ester A TMPT ; Ogumont T 200 ; TMPTA ; Viscoat 295 ; 2-Propenoic acid, 1,1'-(2-ethyl-2-(((1-oxo-2-propen-1-yl)oxy)methyl)-1,3-propanediyl) ester . 

When heated to decomposition it emits acrid smoke and irritating fumes. This product is mildly toxic by ingestion. It is irritating to eyes and skin. It may cause sensitization by skin contact. If you want to contact the product, you must wear eye / face protection.

The Trimethylolpropane triacrylate is functional monomer with the appreance is pale yellow to yellow transparent liquid. It has the property of resistance against weather, chemical, water and abrasion. So this product can be used in manufacture of acrylic glue, plastic, adhesive, anaerobic sealant, Ink which is useful in the low volatility and fast cure response.

The other characteristics of this product can be summarized as: (1)ACD/BCF (pH 5.5): 8.09 ; (2)ACD/BCF (pH 7.4): 8.09 ; (3)ACD/KOC (pH 5.5): 155.43 ; (4)ACD/KOC (pH 7.4): 155.43 ; (5)#H bond acceptors: 6 ; (6)#H bond donors: 0 ; (7)#Freely Rotating Bonds: 13 ; (8)Index of Refraction: 1.471 ; (9)Molar Refractivity: 76 cm3 ; (10)Molar Volume: 271.9 cm3 ; (11)Polarizability: 30.13×10-24 cm3 ; (12)Surface Tension: 35.8 dyne/cm ; (13)Enthalpy of Vaporization: 62.91 kJ/mol ; (14)Vapour Pressure: 5.27E-06 mmHg at 25°C.

People can use the following data to convert to the molecule structure. SMILES: O=C(OCC(COC(=O)\C=C)(CC)COC(=O)\C=C)\C=C; InChI: InChI=1/C15H20O6/c1-5-12(16)19-9-15(8-4,10-20-13(17)6-2)11-21-14(18)7-3/h5-7H,1-3,8-11H2,4H3.
