Usage

General Description

Trimethylmethanetricarboxylate, also known as trimethyl trimellitate, is a chemical compound used in the production of plastics, particularly polyethylene terephthalate (PET) resin. It is commonly employed as a plasticizer to improve the flexibility, durability, and heat resistance of PET plastics. Trimethylmethanetricarboxylate is also utilized in the manufacturing of other synthetic materials such as adhesives, coatings, and sealants. This chemical is considered to be a low-toxicity compound, but exposure to high concentrations may cause irritation to the skin, eyes, and respiratory system. It is important to handle and store trimethylmethanetricarboxylate with proper care and adhere to safety protocols to minimize the risk of exposure.

Synthesis and spectroscopic characterization of the first symmetrically and nonsymmetrically substituted fluorinated emerald-green trannulenes C 60F15R3 soluble in polar media and water

The first water-soluble C3V-symmetrical trannulene derivatives of fluorofullerene C60F18 possessing six carboxylic or ammonium ion groups have been synthesized and spectrally characterized. The stability of emerald-green aqueous solutions of these compounds was investigated. A novel, synthetic route was developed for a step-by-step derivatization of C60F18 with different organic C-H acids that: yielded nonsymmetrically substituted C60F15R 2R trannulenes. The synthesized trannulenes were loaded with polar carboxylic groups that improved greatly the solubility of these compounds in aqueous media, We showed that four solubilizing COOH groups could be introduced onto the fullerene cage of C60F15R2R' trannulenes with R substituent and then some additional organic functionality could be attached independently with R', The R' substituent might potentially comprise a ligand responsible for selective targeting of the whole trannulene molecule to some specific tissues or intracellular structures. The demonstrated loading of the fluorofullerene core with polar carboxylic or ammonium groups might be considered as an important step towards the design of sophisticated water-soluble trannulene-based assembles for biomedical applications.

Substituent Effects on the C-C Bond Strength, 19. Geminal Substituent Effects, 10. Radical Stabilization Enthalpies of α,α-Bis(methoxycarbonyl)alkyl and Tris(methoxycarbonyl)methyl Radicals

Heats of formation ΔH0f(g) were determined from enthalpies of combustion ΔH0f(c) and enthalpies of vaporization ΔH0vap or sublimation ΔH0sub for the eight substituted methanetricarboxylates 2a-h.From these data and from previously determined enthalpies of formation ΔH0f of substituted malonic esters new thermochemical group increments were derived.From these increments and from the recently published improved increments for carboxylic acid esters the gem. interaction enthalpies of two and three COOR groups were calculated.The radical stabilization enthalpies RSE of α,α-bis(methoxycarbonyl)alkyl (18.2 kJ mol-1, 1a) and tris(methoxycarbonyl)methyl radicals (5.2 kJ mol-1, 1b) were derived from kinetic data obtained by means of our previously developed protocol.They were corrected for the gem. interaction energies of the ester groups in the ground state and are satisfactorily explained by an additive stabilizing effect for the ester substituents and by dipolar substituent interactions in the radicals.The dipolar energies were taken from MM2 calculations. - Keywords: Enthalpies of formation / Geminal substituents, energetic interaction of / Bond cleavage, C-C, kinetics of / Radicals, stabilization of / Increments, thermochemical, of esters
