Characterization of Trimethylolpropane‐Based Biolubricant

European Journal of Lipid Science and Technology, 2020
AbstractThe oxidative stability index (OSI) of fatty acid methyl esters (FAME) and trimethylolpropane (TMP) esters or TMPE produced from five vegetable oils (Brassica rapa L., Linum usitatissimum L., Zea mays L., Brassica napus L., Camelina sativa L.) are compared.

A relaxation time study of molecular motion in trimethylolpropane triacrylate and trimethylolpropane trimethacrylate

Chemical Physics, 1989
Abstract Proton NMR relaxation times, T 1 , T 2 , and T 1ϱ , have been measured as a function of temperature in trimethylolpropane triacryla (TMPTA) and trimethylolpropane trimethacrylate (TMPTMA). The results for TMPTA and TMPTMA are very similar.

Kinetic investigations of trimethylolpropane–diisocyanate reactions

Journal of Applied Polymer Science, 2006
AbstractTrimethylolpropane (TMP) is frequently used as a trifunctional branching and chain‐extending agent in polyurethane production. This article deals with the analysis of the reactivities of the three primary hydroxyl groups of TMP during reactions with two exemplary diisocyanates: aromatic diphenylmethane‐4,4′‐diisocyanate and aliphatic m ...

An NMR study of the electron beam‐induced polymerization of trimethylolpropane triacrylate and trimethylolpropane trimethacrylate

Journal of Polymer Science Part B: Polymer Physics, 1991
AbstractElectron beam‐induced polymerization of trimethylolpropane triacrylate (TMPTA) and its methacrylate analog (TMPTMA) was studied using nuclear magnetic resonance (NMR) relaxation time measurements. Free induction decays (FID) of partially polymerized samples consist of a short Gaussian component and a longer component comprised of a distribution

Esterification of trimethylolpropane with fatty acids

Chemistry and Technology of Fuels and Oils, 1967
1. It has been shown that sodium bisulfate in an amount of 3–5% significantly shortens the reaction time compared with the most widely used catalysts in esterification of trimethylolpropane with fatty acids; it simplifies subsequent treatment of the reaction mixture, and increases the yield of ester.
