Butanediol
Butanediol, also called butylene glycol, may refer to any one of four stable structural isomers: * 1,2-Butanediol * 1,3-Butanediol * 1,4-Butanediol *2,3-Butanediol Geminal diols There are also two geminal diols (gem-diols), which are less stable: *1,1-Butanediol, hydrate of butanal *2,2-Butanediol, hydrate of butanone Isobutylene glycol and methylpropanediol Isobutylene glycol may be considered a kind of butylene glycol, similarly to butane historically including ''n''-butane and ''i''-butane (isobutane). The modern name for the closely related type of compounds is methylpropanediol. There are two stable structural isomers: *2-methylpropane-1,2-diol *2-methylpropane-1,3-diol and one unstable geminal diol: *2-methylpropane-1,1-diol (not a glycol), hydrate of 2-methylpropanal (isobutyraldehyde) These three methylpropanediols are structural isomers of butanediols. They are not chiral. Examples 2-Methylpropane-1,3-diol derivatives: * Crisnatol, an experimental medication * 2-Methy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1,2-Butanediol
1,2-Butanediol is the organic compound with the formula HOCH(HO)CHCHCH. It is classified as a ''vic''-diol (glycol). It is chiral, although typically it is encountered as the racemic mixture. It is a colorless liquid. Preparation This diol was first described by Charles-Adolphe Wurtz in 1859. It is produced industrially by hydration of 1,2-epoxybutane.. : This process requires a ten- to twenty-fold excess of water to suppress the formation of polyethers. Depending on the amount of excess water, the selectivity varies from 70 to 92%. Sulfuric acid or strongly acidic ion exchange resins may be used as catalysts, which allows the reaction to occur under 160 °C and at slightly above atmospheric pressure. 1,2-Butanediol is a byproduct of the production of 1,4-butanediol from butadiene.. It is also a byproduct of the catalytic hydrocracking of starches and sugars such as sorbitol to ethylene glycol and propylene glycol. It can also be obtained from the dihydroxylation of ...

Dimethoxyethane
Dimethoxyethane, also known as glyme, monoglyme, dimethyl glycol, ethylene glycol dimethyl ether, dimethyl cellosolve, and DME, is a colorless, aprotic, and liquid ether that is used as a solvent, especially in batteries. Dimethoxyethane is miscible with water. Production Monoglyme is produced industrially by the reaction of dimethylether with ethylene oxide: :CH3OCH3 + CH2CH2O → CH3OCH2CH2OCH3 Applications as solvent and ligand left, 144px, Structure of the coordination complex NbCl3(dimethoxyethane)(3-hexyne). Together with a high-permittivity solvent (e.g. propylene carbonate), dimethoxyethane is used as the low-viscosity component of the solvent for electrolytes of lithium batteries. In the laboratory, DME is used as a coordinating solvent. Dimethoxyethane is often used as a higher-boiling-point alternative to diethyl ether and tetrahydrofuran. Dimethoxyethane acts as a bidentate ligand for some metal cations. It is therefore often used in organometallic chemist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-Ethoxyethanol
2-Ethoxyethanol, also known by the trademark Ethyl cellosolve, is a solvent used widely in commercial and industrial applications. It is a clear, colorless, nearly odorless liquid that is miscible with water, ethanol, diethyl ether, acetone, and ethyl acetate. 2-Ethoxyethanol is manufactured by the reaction of ethylene oxide with ethanol. As with other glycol ethers, 2-ethoxyethanol has the useful property of being able to dissolve chemically diverse compounds. It will dissolve oils, resins, grease, waxes, nitrocellulose Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and ..., and lacquers. This is an ideal property as a multi-purpose cleaner, and, therefore, 2-ethoxyethanol is used in products such as varnish removers and degreasing solutions. References External links *CDC - NIOSH ...

1,3-Butanediol
1,3-Butanediol is an organic compound with the formula CH3CH(OH)CH2CH2OH, not to be confused with 1,4 Butanediol. With two alcohol functional groups, the molecule is classified as a diol. The compound without the R (or D) designation is racemic, which is what has been used in most studies before 2023. The compound is a colorless, bittersweet, water-soluble liquid. It is one of four common structural isomers of butanediol. It is used in grape flavoring, and as a precursor to some antibiotics. Production and uses Hydrogenation of 3-hydroxybutanal gives 1,3-butanediol: :CH3CH(OH)CH2CHO + H2 → CH3CH(OH)CH2CH2OH Dehydration of 1,3-butanediol gives 1,3-butadiene: :CH3CH(OH)CH2CH2OH → CH2=CH-CH=CH2 + 2H2O Pharmacology 1,3-Butanediol has sedative, hypotensive and hypoglycaemic action comparable to ethanol, with the (R), also known as (D), enantiomer being more active. Fatty acid esters of 1,3-butanediol such as the acetoacetate, lactate or hexanoate have been researched fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2,3-Butanediol
2,3-Butanediol is the organic compound with the formula (CH3CHOH)2. It is classified as a ''vic''-diol (glycol). It exists as three stereoisomers, a chiral pair and the meso isomer. All are colorless liquids. Applications include precursors to various plastics and pesticides. Isomerism Of the three stereoisomers, two are enantiomers (levo- and dextro-2,3-butanediol) and one is a meso compound. The enantiomeric pair have (2''R'', 3''R'') and (2''S'', 3''S'') configurations at carbons 2 and 3, while the meso compound has configuration (2''R'', 3''S'') or, equivalently, (2''S'', 3''R'').

Tert-Butyl Hydroperoxide
''tert''-Butyl hydroperoxide (tBuOOH) is the organic compound with the formula (CH3)3COOH. It is one of the most widely used hydroperoxides in a variety of oxidation processes, like the Halcon process. It is normally supplied as a 69–70% aqueous solution. Compared to hydrogen peroxide and organic peracids, ''tert''-butyl hydroperoxide is less reactive and more soluble in organic solvents. Overall, it is renowned for the convenient handling properties of its solutions. Its solutions in organic solvents are highly stable. Application Industrially, ''tert''-butyl hydroperoxide is used to prepare propylene oxide. In the Halcon process, molybdenum-based catalysts are used for this reaction: :(CH3)3COOH + CH2=CHCH3 → (CH3)3COH + CH2OCHCH3 The byproduct t-butanol can be dehydrated to isobutene and converted to MTBE. On a much smaller scale, ''tert''-butyl hydroperoxide is used to produce some fine chemicals by the Sharpless epoxidation. Synthesis and production Many synt ...
