|
| Over time, however, it oxidizes and chemically degrades to form alcohols, ketones, aldehydes, acids and esters. |
|
| The lipid hydroperoxide thus formed will decompose into alkoxy radicals, aldehydes, alkenes, epoxides and alcohols. |
|
| Experience in distilling aldehydes led us to believe that acetaldehyde would form acetals in the overheads of the low pressure column. |
|
| The fumes also contain sulfur dioxide, and various aldehydes, primarily formaldehyde as well as acetaldehyde and acrolein. |
|
| The predominant emissions from uncoated wood and wood-based materials were aldehydes, mainly acetaldehyde, propanal, butanal, pentanal, hexanal, and acetone. |
|
| Water, ethanol, volatile organic acids, aldehydes, esters, acetals, and ketones, many of them powerfully aromatic, are among the azeotrope components in wines. |
|
| Included among these compounds are some of the best known of all chemical families, including the hydrocarbons, alcohols, ethers, aldehydes and ketones, and organic acids. |
|
|
|
| They are either reduced by glutathione peroxidases to unreactive fatty acid alcohols or they react with metals to produce epoxides, aldehydes, etc. |
|
| Individuals who are taurine deficient may become more susceptible to tissue damage by xenobiotic agents such as aldehydes, chlorine, and certain amines. |
|
| In the case of aldehydes and ketones containing carbonyl groups, the highly nucleophilic Grignard reagent contributes its electron pair to form a bond with the carbon atom. |
|
| These reactive aldehydes form specific cross-links between two chains. |
|
| Lactones, phenolic aldehydes, terpenes and wood tannins are all by-products of oak, so it is understandable that too much can rob a white wine of its fruit and delicacy. |
|
| The emitted VOC belonged exclusively to the substance classes of terpenes and aldehydes. |
|
| Alcohols can be oxidised to give aldehydes, ketones or carboxylic acids, or they can be dehydrated to alkenes. |
|
| We then discovered a one pot synthesis of secondary amines on silica surfaces starting with primary amines and aldehydes or ketones. |
|
| They measured the amount of PAH, aldehydes, and total particulate matter produced in the breathing zone of the cook. |
|
| The BHA reacts with aldehydes to form oximes that are less volatile and more stable than the aldehydes. |
|
| Since separation of these cuts was not practicable, the idea of dehydrogenating the alcohols to form aldehydes and ketones was developed. |
|
| The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke. |
|
| Purpald specifically forms a bicyclic heterocycle with aldehydes and changes from colorless to purple on oxidation. |
|
| Lead is one of three metals used in the Oddy test for museum materials, helping detect organic acids, aldehydes, and acidic gases. |
|
| The products of the CuAO-catalysed oxidative deamination of amines are various aldehydes, ammonia, and hydrogen peroxide. |
|
| Many primary alcohols are metabolized into aldehydes then to carboxylic acids whose toxicities are similar to acetaldehyde and acetic acid. |
|
| Within many mammalian systems aldehyde dehydrogenases convert toxic aldehydes into more manageable carboxylic acids. |
|
| The scientists found that heating up vegetable oils led to the release of high concentrations of chemicals called aldehydes. |
|
| Tertiary alcohols cannot be metabolized into aldehydes and as a result they cause no hangover or toxicity through this mechanism. |
|
| The bog chemical environment involves a completely saturated acidic environment, where considerable concentrations of organic acids and aldehydes are present. |
|
|
|
| Reagents useful for the transformation of primary alcohols to aldehydes are normally also suitable for the oxidation of secondary alcohols to ketones. |
|
| The method claimed for imparting nonvolatility to the smelly aldehydes was the facile reaction of the carbonyl groups thereof with primary amines to form imines. |
|
| It is known that allergoids obtained by treatment with aldehydes are randomly cross-linked proteins of high molecular weight and their standardization is very difficult. |
|
| Extraction in particular results in whisky acquiring a number of compounds, including aldehydes and acids such as vanillin, vanillic acid, and syringaldehyde. |
