Degree of completion

It follows that the position of thermodynamic equilibrium will change along the reactor for those reactions in which a change of tire number of gaseous molecules occurs, and therefore that the degree of completion and heat production or absorption of the reaction will also vaty. This is why the external control of the independent container temperature and the particle size of the catalyst are important factors in reactor design. [Pg.144]

ORP Oxidation reduction potential - the degree of completion of a chemical reaction by detecting the ratio of ions in the reduced form to those in the oxidized form as a variation in electrical potential measured by an ORP electrode assembly. OSHA The Williams-Steiger Occupational Safety and Health Act of 1970 (OSHA) is a law designed to protect the health and safety of industrial workers and treatment plant operators. It regulates the design, construction, operation and maintenance of industrial plants and wastewater treatment plants. The Act does not apply directly... [Pg.620]

The degree of completion of a reaction refers to the fraction of the limiting reactant that has been converted into products. [Pg.335]

The most common air-pollution descriptor is the expression smoke . For the purposes of the 1956 and 1968 Acts, smoke includes soot, ash, grit and gritty particles emitted in smoke. Smoke is intended to mean the visible products of combustion and not the invisible ones (CO2, SO2, NOx, etc.) and is used to indicate the degree of completeness of combustion (if combustion is 100 per cent smoke is produced). [Pg.758]

The use of zeolites can also be very helpful in removing a reaction product that unfavourably influences the yield of the desired product. Thus, in the manufacture of antibiotic cefoxitin, the amide acylation results in the generation of HCI, which can be removed by the addition of molecular sieve 3 A or 4 A, which has a large capacity for HCI (Weinstock, 1986). Other examples are reactions in which products like methanol or water retard the rate and prevent the reaction to reach the desired degree of completion. Molecular sieves capture methanol or water very well. [Pg.154]

Hydrogen-bonding is essentially a partial proton-transfer reaction. Thus, the ionic-resonance mnemonic (5.29a), which expresses the partial covalency of H-bonding, suggests an immediate relationship to the degree of completion of the actual proton-transfer reaction... [Pg.652]

A more subtle chemical influence is the variation of the anion associated with a cationic spin crossover system, or of the nature and degree of solvation of salts or neutral species. These variations can result in the displacement of the transition temperature, even to the extent that SCO is no longer observed, or may also cause a fundamental change in the nature of the transition, for example from abrupt to gradual. The influence of the anion was first noted for salts of [Co(trpy)2]2+ [142] and later for iron(II) in salts of [Fe(paptH)2]2+ [143] and of [Fe(pic)3]2+ [127]. For the [Fe(pic)3]2+ salts the degree of completion and steepness of the ST curve increases in the order io-dide[Pg.41]

A numerical optimization procedure which keeps track of all these factors has heen published by Schweikert, Krieg and Noack (67). The algorithm used in this procedure is almost unique as far as we know, there is only one alternative published by Kimmich et al. (73), that achieves a similar degree of completeness. [Pg.416]

In the discussion to follow certain aspects of chemical shifts and nuclear spin-spin interactions will be reviewed. However, it is not our intention to give the theories of these effects with any degree of completeness since excellent treatments may be found in reviews and the original literature 108). We only hope here to point out some results and approaches of NMR particularly applicable to inorganic systems. Let it suffice at this point to say that chemical shifts of nuclei arise from shielding effects of nearby electrons. The field Hm seen by the nucleus is not the externally applied field 770, but... [Pg.232]

It is in the technique of solidifying the mass that plastisol propellants differ so markedly from composite propellants. In composite propellants, the nonvolatile liquid is comprised of monomers or low molecular weight prepolymers. Solidification is accomplished by completion of the polymerization reactions. Much attention must be given to the degree of completion of these reactions during manufacture so as to minimize changes in physical properties as a consequence of continued slow polymerization, or so-called post-cure, following manufacture. [Pg.45]

The result a are compared to a standard expl, such as picric icid, gunpowder or mercury fulminate, and expressed as a ratio known as figure of insensitiveness. This ratio represents the relative energies of the impact required to produce explosions of equal degrees of completeness from initial decomposition to complete detonation. Picric Acid is taken as 100, and explosives giving higher numbers are less sensitive while those giving lower numbers are more sensitive than picric acid. Ref R.Robertson, JCS 119 1,15(1921)... [Pg.709]

As is normally the case with esterification reactions, an equilibrium situation exists in this particular series, and Reaction 2, with respect to its degree of completion is dependent upon the concentration of the olefin in the reaction medium. We studied the effect of the olefin excess in the reaction on yield of ester and found that at levels less than 50%, the yields based on the acid-ester components were considerably less. With olefin excesses larger than 50%, the rate of the primary reaction, that is formation of the diester, was decreased. We therefore determined that an olefin excess of about 50% favored the primary reaction (number 2) as opposed to the secondary reaction in which the olefin can undergo polymerization in the acid media. [Pg.76]

Although this evidence indicates that the experimentals as a group achieved to a statistically significant degree a higher score in each of the nine categories than did the controls, the degree of completeness or intensity must be examined. [Pg.156]

The control subjects did not experience many phenomena of the mystical typology, and even then only to a low degree of completeness. The phenomena for which the scores of the controls were closest to (although still always less than) the experimentals were blessedness and peace, sense of sacredness, love, and persisting positive changes in attitude and behavior toward others and toward the experience. [Pg.158]

A solvent-extraction flowsheet is broken down into sections such as extraction, scrub, and strip. For each section, one or more component in a process fluid must be moved from one phase to the other phase with a specified degree of completeness. The first design problem is to determine the number of stages for each section to accomplish the required component transfer. With the well-defined stages of the centrifugal contactor, the following extraction factor (E) can be used to estimate the number of stages required ... [Pg.589]
