Study of the infrared spectrophotometry and intramolecular hydrogen bonding in the structures of 1,3-glycols was written by Buc, Henri;Neel, Jean. And the article was included in Compt. Rend. in 1961.SDS of cas: 115-84-4 The following contents are mentioned in the article:
cf. Kuhn, CA 53, 9044b. In order to study the intensity of intramol, interaction between hydroxyl groups in poly(vinyl alcohol) a systematic examination of infrared absorption near 3600 cm.-1 for 11 different 1,3-glycols, a 1,3,5-triol, and 7 alcohols was undertaken. All spectra were obtained in CCl4 solution at 25° (unless otherwise stated) using a LiF prism (first 6 spectra) or a CaF2 prism. Data for each compound, the free OH frequency ν1, the bonded OH frequency, ν2, the ratio of optical densities τ = D2/D1, the difference in frequencies Δν = ν1 – ν2, and Δμ’ the difference in frequency of the OH involved in the chelation, follow: 1,3-propanediol, 3635, 3557, 0.46, 78, -; PrOH, 3634, -, -, -, -; dl-1,3-butanediol, 3628, 3550, 0.92, 78, 84; BuOH, 3634, -, -, -, -; sec-BuOH, 3626, -, -, -, -; tert-BuOH, 3619, -, -, -, -; 1,3-propanediol, 3636, 3557, 0.45, 79, -; 2,2-dimethyl-1,3-propanediol, 3629, 3545, 0.50, 94, -; 2,2-diethyl-1,3-propanediol, 3639, 3545, 0.52, 94, -; 2-methyl-2-propyl-1,3-propanediol, 3639, 3545, 0.55, 94, -; 2-ethyl-2-butyl-1,3-propanediol, 3638, 3546, 0.51, 92, -; β-2,4-pentanediol, 3626, 3532, 1.52, 94, -; β-2,4-pentanediol, 3626, 3532, 0.81, 94, -; dl-2-methyl-2,4-pentanediol, 3614 (shoulder at 3628), 3529, 1.83, 85, 95; 2-pentanol, 8625, -, -, -, -; 1,5-pentanediol (65°), 3636, 3541, 0.09, 95, -; dl-1,3,5-pentanetriol, 3633 (shoulder at 3640), 3531, 1.07, 102, 105; 1-pentanol (65°), 3636, -, -, -, -; 3-pentanol (65°), 3632, -, -, -, -. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4SDS of cas: 115-84-4).
2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.SDS of cas: 115-84-4
