Combustion, heat Physical properties

Infrared, uv, nmr spectra (66), and photoelectron spectra have been reviewed (67). Physical properties of siHcon peroxides are summarized in Reference 43. Other physical properties, eg, dipole moments, dihedral angles, and heats of combustion ate Hsted in Reference 68. The oxygen—oxygen bond strengths of various diaLkyl peroxides have been reported (69). [Pg.106]

Brackets signify a trivial name no longer ia use. At 101.3 kPa = 1 atm unless otherwise noted ia kPa as a subscript. At 20°C unless otherwise noted by a superscript number (°C). At 20°C unless otherwise noted. To convert to cal, divide by 4.184. 70°C. Heat of combustion (Uquid). At50°C. To convert kPa to mm Hg, multiply by 7.5. In the alkenoic series of molecular formula 2 2 metbacrylic, undecjlenic, oleic, and emcic acids have important appHcations (Table 2). Acryhc and metbacrylic acids have a petrochemical origin, and undecylenic, oleic, and emcic acids have natural origins (see Acrylic ACID AND DERIVATIVES Methacrylic acid and derivatives). Table 2.

The material in this section is divided into three parts. The first subsection deals with the general characteristics of chemical substances. The second subsection is concerned with the chemistry of petroleum it contains a brief review of the nature, composition, and chemical constituents of crude oil and natural gases. The final subsection touches upon selected topics in physical chemistry, including ideal gas behavior, the phase rule and its applications, physical properties of pure substances, ideal solution behavior in binary and multicomponent systems, standard heats of reaction, and combustion of fuels. Examples are provided to illustrate fundamental ideas and principles. Nevertheless, the reader is urged to refer to the recommended bibliography [47-52] or other standard textbooks to obtain a clearer understanding of the subject material. Topics not covered here owing to limitations of space may be readily found in appropriate technical literature. [Pg.297]

Constitution XV for sucrose has up to the present satisfied all demands made upon it. Like its precursors, I and II (page 6), it was not incompatible with physical properties of sucrose such as the magnetic rotation, or the parachor, although the latter claim has been denied. Von Lippmann lists a great many early determinations of the physical properties of the sugar more recent measurements include the heat of combustion, the molecular weight in liquid ammonia, and various optical and electrical constants. ... [Pg.16]

Initially, we will be concerned with the physical properties of alkanes and how these properties can be correlated by the important concept of homology. This will be followed by a brief survey of the occurrence and uses of hydrocarbons, with special reference to the petroleum industry. Chemical reactions of alkanes then will be discussed, with special emphasis on combustion and substitution reactions. These reactions are employed to illustrate how we can predict and use energy changes — particularly AH, the heat evolved or absorbed by a reacting system, which often can be estimated from bond energies. Then we consider some of the problems involved in predicting reaction rates in the context of a specific reaction, the chlorination of methane. The example is complex, but it has the virtue that we are able to break the overall reaction into quite simple steps. [Pg.69]
