Ethyl 2-hydroxy-3-phenylpropanoate (cas: 15399-05-0) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Computed Properties of C11H14O3
The preparation and properties of a platinized charcoal catalyst with some observations on the behavior of inhibitors was written by Baltzly, Richard. And the article was included in Journal of the American Chemical Society in 1952.Computed Properties of C11H14O3 This article mentions the following:
A Pt-C catalyst (I) notable for its inactivity in debenzylation and in dehalogenations has been developed and tested on a variety of reducible compounds It appears to reduce aliphatic CO compounds less readily than aromatic. Both I and Pd-C are inhibited toward the reduction of control substrates by bases and nucleophilic ions. To 1 g. C (Darco G-60) in the reducing bottle of a Burgess-Parr hydrogenator was added 30-50 cc. H2O and solutions of H2PtCl6 and PdCl2 containing 100 mg. Pt and 0.2 mg. Pd, resp., the bottle evacuated, filled with H, shaken 15-20 min., and the H2O finally replaced by MeOH; when not in use, the I was stored under MeOH in a reducing bottle. The hydrogenations with I were performed in MeOH at room temperature, in general with 50 millimoles substrate in 50 cc. MeOH. A series of hydrogenations was carried out in this manner; the substrate, the hydrogenation absorption, and, where determined, the hydrogenation products, of these runs are listed in the following (H absorption rates of 5-10 millimoles/min. are marked fast, 1-5 millimoles/min. moderate, < 1 millimole/min. slow; products in parentheses were not specifically isolated but were present with reasonable certainty): cyclohexene, 1 mole very fast (cyclohexane); CH2:CHCH2-Cl, 1 mole moderate (C3H8, PrCl, HCl); PhCH2Cl, 1 mole slow (PhMe); PhCH2OH, about 0.2 mole very slow (Ph-Me ?, substrate possibly contaminated with PhCH2Cl); (PhCH2)2O, none; PhCH2OCONHCH2CO2H, none; PhNMeCH2Ph.HCl, none; p-ClC6H4NH2, none; o-ClC6H4NH2, none; m-BrC6H4Me, none; o-BrC6H4OMe, very slow, -; o-BrC6H4CO2Et, none; p-ClC6H4OC6H4NO2-p, 3 moles, very fast, p-ClC6H4OC6H4NH2-p; (PhN:)2 + 2 moles AcOH, 1 mole very fast, 1 mole moderate (PhNH2); (PhN:)2, 1 mole very fast, 1 mole slow [PhNH2, (PhNH)2]; (PhN:)2 in 0.019N NaOH, 1 mole very fast, (PhNH)2; 2, 6-dimethyl-4-hydroxy-5-phenylazo-4-pyrimidinol-HCl, 2 moles fast, 5-amino-2,6-dimethyl-4-pyrimidinol (+ Ph-NH2); PhCH:NMe, fast, PhCH2NHMe; p-MeOC6H4-CH:NCHPhMe + 1.5 moles AcOH, fast, p-MeOC6H4CH2-NHCHPhMe; 2, 5-(MeO)2C6H3COC(:NOH)Me + 3 moles HCl, 2 moles moderate, 2, 5-(MeO)2C6H3COCH(NH2)Me.-HCl; PhCN + HCl, none; PhCH2CN + HCl, none; PhCH2C(:NOH)Ph, none; AcH, very slow (EtOH) AcH + morpholine, 1 mole moderate (ethylmorpholine); cyclohexanone, none; Me2CO, none; Me2CO + cyclohexylamine, very slow, -; p-MeOC6H4CHO, 1 mole moderate (anisyl alc.); p-MeOC6H4CHO + BuNH2, 1 mole slow, p-MeOC6H4CH2NHBu; p-HOC6H4Ac, 1 mole slow, polymerized product; PhCH:CHCHO, 2 moles moderate (Ph(CH2)3OH); AcCH2CO2Et, none; BzCH2CO2-Et, 1 mole slow, PhCH(OH)CH2CO2Et; 3, 4-MeO(HO)-C6H3CH:CAcCO2Et, 1 mole moderate, 3, 4-MeO(HO)-C6H3CH2CHAcCO2Et; 3,4-(MeO)2C6H3CH: CAcCO2Et, 1 mole moderate, 3, 4-(MeO)2C6H3CH2CHAcCO2Et; Ph2CO, none; PhCH2Bz, none; benzanisoine, none; C6H6 in glacial AcOH, slow not carried to completion (cyclohexane ?); C10H8 in glacial AcOH, none at 25°. Both I and Pd-C were tested with control substrates in the presence of various concentrations of inhibitors and the half-inhibitory M concentrations (given for I and Pd-C) determined for: MeO– 0.001, 0.001; PhO– 0.006, 0.006; I– 0.0004, 0.0004; CN– < 0.001, -; NH3 0.002, 0.002; PhCH2NMe2 0.001, 0.001; and p-MeC6H4NH2 0.007, 0.005-0.006. In the experiment, the researchers used many compounds, for example, Ethyl 2-hydroxy-3-phenylpropanoate (cas: 15399-05-0Computed Properties of C11H14O3).
