Calorimetric and computational study of (1H-Indol-n-yl)methanol and 2-(1H-Indol-n-yl)ethanol (n=2, 3) was written by Carvalho, Tania M. T.;Amaral, Luisa M. P. F.;Morais, Victor M. F.;Ribeiro da Silva, Maria D. M. C.. And the article was included in Thermochimica Acta in 2019.COA of Formula: C7H8O2S This article mentions the following:
In the present work, the gas-phase standard molar enthalpy of formation of 2-(1H-indol-3-yl)ethanol was derived, at T = 298.15 K, from the enthalpy of combustion for the crystalline compound, measured by static-bomb calorimetry, and its enthalpy of sublimation obtained from Calvet microcalorimetry measurements. The standard molar enthalpies of formation of this compound and for (1H-indol-2-yl)methanol, (1H-indol-3-yl)methanol and 2-(1H-indol-2-yl)ethanol were calculated using the composite G3 method. The exptl. value of the gas-phase enthalpy of formation of 2-(1H-indol-3-yl)ethanol is -(48.5 ± 3.3) kJ mol-1, being in excellent agreement with the G3 value, thus giving confidence to the estimates The results were analyzed in terms of the enthalpic methylene increments and compared with other related systems. In the experiment, the researchers used many compounds, for example, Methyl 2-thienylacetate (cas: 19432-68-9COA of Formula: C7H8O2S).
Methyl 2-thienylacetate (cas: 19432-68-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.COA of Formula: C7H8O2S
