Compound compounded function

Independent compounders supply custom and proprietary compounds or otherwise specialize in compounding filled/reinforced, color-matched, flame-retarding, antistatic, or masterbatch compounds. Compounding functions are also performed by primary resin suppliers, by additives or masterbatch suppliers, and by some large processors, internally or in-line with forming processes [2-16]. [Pg.24]

Inert Gas Dilution. Inert gas dilution involves the use of additives that produce large volumes of noncombustible gases when the polymer is decomposed. These gases dilute the oxygen supply to the flame or dilute the fuel concentration below the flammability limit. Metal hydroxides, metal carbonates, and some nitrogen-producing compounds function in this way as flame retardants (see Flame retardants, antimony and other inorganic compounds). [Pg.465]

Biochemically, most quaternary ammonium compounds function as receptor-specific mediators. Because of their hydrophilic nature, small molecule quaternaries caimot penetrate the alkyl region of bdayer membranes and must activate receptors located at the cell surface. Quaternary ammonium compounds also function biochemically as messengers, which are generated at the inner surface of a plasma membrane or in a cytoplasm in response to a signal. They may also be transferred through the membrane by an active transport system. [Pg.378]

Many compounds capable of chelation have been tested for antimicrobial properties. Those showing positive results include saHcylaldoxime [94-67-7] l-nitroso-2-naphthol [131-91-9] mercaptobenzothiazol [149-30-4], dimethylglyoxime [95-45-4], saHcylaldehyde [90-02-8], cupferron [135-20-6], phenanthroline [66-71-7], isoniazid [54-85-3], thiosemicarbazones, the sulfur analogue of oxine, and numerous antibiotics (qv) including tetracyclines. Whether these compounds function exclusively, partially, or at all by virtue of their abiHty to chelate is open to debate. [Pg.131]

Pyridones and other six membered compounds (functional tautomerism)... [Pg.13]

Pyridones and other six-membered compounds (functional tautomerism). The pyridone /hydroxypyridine tautomerism (76AHCS1, p. 87), especially 2-pyridone (15a)/2-hydroxypyridine (15b), has received more attention from theoreticians than any other example of tautomerism, probably in part because it is a simple model for biologically important molecules such as thymine, cytosine, and uracil (Scheme 8). [Pg.14]

Pyrazolinones and other five-membered compounds (functional tautomerism). These studies have often used the most simple but rather experimentally neglected pyrazolin-5-one 19. Its four tautomers are called CH 19a, NH 19b, 5-OH 19c, and 3-OH 19c (Scheme 10) [76AHCS1, p. 313]. [Pg.16]

Although this method is aot a geaeral procedure, bemg specific for ct-nitroketoues, k has several merits to avoid the use of toxic reageuts such as organodn compounds Functionalized ketones have been prepared by this denitration reaction, in which functionalized nitroalkanes are used as alkyl anion synthons For example, 3-nitropropanal ethylene acetal can be used as synthon of the 3-oxo-propyl anion and 1,4-dicarbonyl compounds are prepared, as shovm In Eq 7 88... [Pg.212]

Diazoester aziridinations may be carried out in ionic liquids [39]. Other carbene equivalents have been investigated in aziridination reactions, though not to the same extent as diazocarbonyl compounds. Dibromo(tert-butyldimethylsilyl)me-thyllithium, for example, aziridinates N-arylimines to give l-bromo-2-aryl-3-silyla-ziridines these compounds function as useful synthetic intermediates, reacting... [Pg.131]

There is an extremely wide range of potentially useful chemical treatments available, and for any boiler system, proper selection, utilization, and control are vital considerations that may largely determine the ultimate success of the overall program. These chemicals usually are organized by type of compound, function, mode of action, or similar classification, but, because many chemicals are multifunctional in character, may be used in either a primary or supplementary (adjunct or conjunctional treatment) role, and additionally may be branded (especially many modem polymers) or otherwise disguised, such classifications may be quite arbitrary. [Pg.385]

Peroxide decomposers—These function by reacting with the initiating peroxides to form nonradical products. Presumably mercaptans, thiophenols, and other organic sulfin compounds function in this way [19]. It has been suggested that zinc dialkyldithiocarbamates function as peroxide decomposers, thus giving mbber compounds good initial oxidative stability. [Pg.467]

The hydrocarbons 54 and 5551) which are functional group-free analogues of 26 and 38 display no activities of inclusion formation, either with polar or with apolar solvents371. This result is another proof that mostly for the roof-shaped type of compounds, functional groups play a fundamental role in the construction of a low-density packed crystal lattice. [Pg.84]

Borges, R.A., Puri, A., Krebs, F.C., Wigdahl, B., Blumenthal, R., Rawat, S.S., Johnson, B.T., and Schengrund, C.-L. (2005) Multivalent compounds functionalized with the carbohydrate headgroups of immune cell-surface GSLs as inhibitors of HIV-1 infection. 3rd IAS Conference on HIV Pathogenesis and Treatment, Rio de Janeiro, July 24-27. [Pg.1049]

When a coordination compound functions as a catalyst, there are usually several steps in the process. The entire collection of steps constitutes the mechanism of the reaction. Before describing several of the important catalytic processes, we will describe the types of reactions that often constitute the elementary steps. [Pg.780]

In the aforementioned compounds, functional derivatization, described83 to increase the dispersion of their n.m.r. spectra, caused63 enhanced rate of lactone hydrolysis (apparent from their electrolytic conductivities). [Pg.207]

There are two distinct classes of compounds that fit the criteria mentioned above alkene-functionalized chalcone derivatives (Fig. IB) and enone-functionalized chalcone derivatives (Fig. 1C). Within each class, both aromatic and non-aromatic compounds exist. Those compounds functionalized at the alkene include i) 3-membered heterocycles, e.g., epoxide and aziri-dine compounds, ii) 5-membered aromatic derivatives including fused and non-fused compounds, and iii) 6-membered aromatic pyrazine compounds. The enone-functionalized compounds include i) 5-membered aromatics such as pyrazole and isoxazole compounds, ii) 5-membered non-aromatic compounds for example pyrazolines and isoxazolines, and iii) 6-membered non-aromatics where a discussion of heterocyclic and non-heterocyclic compounds will be given for completeness. [Pg.50]

The labile cycloadduct 262 of azodibenzoyl to cyclopentadiene rearranges to the fused oxadiazine 263 on heating. The process involves dissociation of 262 into its components, followed by a Diels-Alder reaction in which the azo compound functions as a hetero diene (equation 142)135. [Pg.532]

In the Lewis acid catalysed reactions of a,/J-unsaturated carbonyl compounds with dienes, sometimes the products of a [2 + 4]-cycloaddition, where the carbonyl compounds function as heterodienes, were isolated. It was proposed that the intermediate of the [2 + 4]-cycloaddition is formed first in this case, followed by a Cope rearrangement which leads to the normal Diels-Alder product (Scheme 7). [Pg.1048]

The oxidation of dihydropyridine-based chemical delivery systems (CDSs) pioneered by Bodor and co-workers [176] has been discussed in a previous book (Chapt. 13 in [81]). There, we examined the principles by which such compounds function to deliver drugs to the brain. Here, we focus our attention to the last step in the activation of these double prodrugs, namely hydrolysis to release the drug. [Pg.506]

S.3 Cytochrome P450 Model Compounds Functional. Ferric-peroxo species are part of the cytochrome P450 catalytic cycle as discussed previously in Section 7.4.4. For instance, these ferric-peroxo moieties are known to act as nucleophiles attacking aldehydic carbon atoms in oxidative deformylations to produce aromatic species.An example of this work, establishing the nucleophilic nature of [(porphyrin)Fe (02)] complexes, was achieved for alkene epoxidation reactions by J. S. Valentine and co-workers. The electron-deficient compound menadione (see Figure 7.18) yielded menadione epoxide when reacted with a [(porphyrin)Fe X02)] complex. [Pg.374]
