2-propylheptanol
2-Propylheptanol (2PH) is a colourless waxy or oily solid. Production 2-Propylheptanol is an oxo alcohol, meaning that it is produced from the hydroformylation ("oxo synthesis") of C4 alkenes followed by hydrogenation of the resulting aldehyde. The production route is similar to that for 2-Ethylhexanol 2-Ethylhexanol (abbreviated 2-EH) is an organic compound with formula CHO. It is a branched, eight-carbon chiral alcohol (chemistry), alcohol. It is a colorless liquid that is poorly soluble in water but soluble in most organic solvents. It is prod .... Applications Such compounds enjoy many applications, including as raw materials for plasticizers, resins, processing solvents, and precursors to detergents. Heat stabilizers manufactured for PVC compounds use similar high boiling and high molecular weight oxo-alcohols, which enhance product performance. A further application area of this C10 alcohol is for the manufacture of oleate- and palmitate-based materials used by the cosmeti ...

2-Ethylhexanol
2-Ethylhexanol (abbreviated 2-EH) is an organic compound with formula CHO. It is a branched, eight-carbon chiral alcohol (chemistry), alcohol. It is a colorless liquid that is poorly soluble in water but soluble in most organic solvents. It is produced on a large scale (>2,000,000,000 kg/y) for use in numerous applications such as solvents, flavors, and fragrances and especially as a precursor for production of other chemicals such as emollients and plasticizers. It is encountered in plants, fruits, and wines. The odor has been reported as "heavy, earthy, and slightly floral" for the R enantiomer and "a light, sweet floral fragrance" for the S enantiomer. Properties and applications The branching in 2-ethylhexanol inhibits crystallization. Esters of 2-ethylhexanol are similarly affected, which together with low volatility, is the basis of applications in the production of plasticizers and lubricants, where its presence helps reduce viscosity and lower freezing points.

Valnoctamide
Valnoctamide (INN, USAN) has been used in France as a sedative-hypnotic since 1964. It is a structural isomer of valpromide, a valproic acid prodrug; unlike valpromide, however, valnoctamide is not transformed into its homologous acid, valnoctic acid, ''in vivo''. Indications In addition to being a sedative, valnoctamide has been investigated for use in epilepsy. It was studied for neuropathic pain in 2005 by Winkler et al., with good results: it had minimal effects on motor coordination and alertness at effective doses, and appeared to be equally effective as gabapentin. RH Belmaker, Yuly Bersudsky and Alex Mishory started a clinical trial of valnoctamide for prophylaxis of mania in lieu of the much more teratogenic valproic acid or its salts. Side effects The side effects of valnoctamide are mostly minor and include somnolence and the slight motor impairments mentioned above. Interactions Valnoctamide is known to increase through inhibition of epoxide hydrolase the serum le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3-Methylheptane
3-Methylheptane is a branched alkane isomeric to octane. Its structural formula is CH3CH2CH(CH3)CH2CH2CH2CH3. It has one stereocenter. Its refractive index In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. The refractive index determines how much the path of light is bent, or ... is 1.398 (20 °C, D).

Valpromide
Valpromide (marketed as Depamide by Sanofi-Aventis) is a carboxamide derivative of valproic acid used in the treatment of epilepsy and some affective disorders. It is rapidly metabolised (80%) to valproic acid (another anticonvulsant) but has anticonvulsant properties itself. It may produce more stable plasma levels than valproic acid or sodium valproate and may be more effective at preventing febrile seizures. However, it is over one hundred times more potent as an inhibitor of liver microsomal epoxide hydrolase. This makes it incompatible with carbamazepine and can affect the ability of the body to remove other toxins. Valpromide is no safer during pregnancy than valproic acid. Valpromide is formed through the reaction of valproic acid and ammonia via an intermediate acid chloride. In pure form, valpromide is a white crystalline powder and has melting point 125–126 °C. It is soluble only in hot water. It is available on the market in some European countries. See also * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-Ethylhexanoic Acid
2-Ethylhexanoic acid is the organic compound with the formula CH3(CH2)3CH(C2H5)CO2H. It is a carboxylic acid that is widely used to prepare lipophilic metal derivatives that are soluble in nonpolar organic solvents. 2-Ethylhexanoic acid is a colorless viscous oil. It is supplied as a racemic mixture. Production 2-Ethylhexanoic acid is produced industrially from propylene, which is hydroformylated to give butyraldehyde. Aldol condensation of the aldehyde gives 2-ethylhexenal, which is hydrogenated to 2-ethylhexanal. Oxidation of this aldehyde gives the carboxylic acid. Metal ethylhexanoates 2-Ethylhexanoic acid forms compounds with metal cations that have stoichiometry as metal acetates. These ethylhexanoate complexes are used in organic and industrial chemical synthesis. They function as catalysts in polymerizations as well as for oxidation reactions as "oil drying agents." They are highly soluble in nonpolar solvents. These metal complexes are often described as sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxo Alcohol
Oxo alcohols are alcohols that are prepared by adding carbon monoxide (CO) and hydrogen (usually combined as synthesis gas) to an olefin to obtain an aldehyde using the hydroformylation reaction and then hydrogenating the aldehyde to obtain the alcohol. An intermediate step of adding two aldehydes together to obtain a larger aldehyde (the aldol condensation reaction) can precede the hydrogenation. Long chain oxo-alcohols are often prepared using alpha-olefins from the Shell higher olefin process, to give secondary alcohols such as isodecyl alcohol. Key oxo alcohols that are sold in commerce include the following: * 2-Methyl-2-butanol (2M2B) * ''n''-Butanol * 2-Ethylhexanol * 2-Propylheptanol * Isononyl alcohol * Isodecyl alcohol Key manufacturers of oxo alcohols include the following companies: * BASF * Dow Chemical Company * Eastman Chemical Company * ExxonMobil Chemical Company * Grupa Azoty * PETRONAS * Sasol Oxo alcohols are used as solvents and are reacted with phthal ...

Aldehyde
In organic chemistry, an aldehyde () is an organic compound containing a functional group with the structure . The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group. Aldehydes are common and play important roles in the technology and biological spheres. Structure and bonding Aldehydes feature a carbon center that is connected by a double bond to oxygen and a single bond to hydrogen and single bond to a third substituent, which is carbon or, in the case of formaldehyde, hydrogen. The central carbon is often described as being sp2- hybridized. The aldehyde group is somewhat polar. The C=O bond length is about 120-122 picometers. Physical properties and characterization Aldehydes have properties that are diverse and that depend on the remainder of the molecule. Smaller aldehydes are more soluble in water, formaldehyde and acetaldehyde completely so. The volatile aldehydes have pungent odors. Al ...
