Inorganic compounds boiling point

For pure inorganic compounds, the method of Gambill was modified to yield Eq. (2-4) and only requires the normal boiling point as input. 

Carbon monoxide (CO) is a colorless and odorless gas molecule. This inorganic compound, at standard temperature and pressure, is chemically stable with low solubility in water but high solubility in alcohol and benzene. Incomplete oxidation of carbon in combustion is the major source of environmental production of CO. When it burns, CO yields a violet flame. The specific gravity of CO is 0.96716 with a boiling point of -190°C and a solidification point of-207°C. The specific volume of CO is 13.8 cu ft/lb (70°F). 

Organic compounds contain covalent bonds. In general, compared to inorganic compounds organic compounds have low melting and boiling points, tend to be flammable, have relatively low densities, do not dissolve readily in water, and are primarily nonelectrolytes. 

Borazine is isoelectronic with benzene, as B=N is with C=C, (Fig. 16.21). in physical properties, borazine is indeed a close analogue of benzene. The similarity of the physical properties of the alkyl-substituted derivatives of benzene and borazine is ever more remarkable. For example, the ratio of the absolute boiling points of the substituted borazines to those of similarly substituted benzene is constant. This similarity in physical properties led to a labeling of borazine as "inorganic benzene." This is a misnomer because tbe chemical properties of borazine and benzene are quite different Both compounds have aromatic rr clouds of electron density with potential for delocalization over all of the ring atoms. Due to the difference m electronegativity between boron and nitrogen, the cloud in borazine is "lumpy" because more electron... 

While D41 decomposes rather continuously in three equidistant steps, G2 shows two early steps of mass loss which are followed by a longer period of stagnation followed by a third step. With the help of the mass spectrum the single steps can be attributed to different events within the decomposition process. The first two steps are caused by the loss of water, obviously evaporated from two different sites of the solid, which explains the separated steps, both more than 150°C above the boiling point of water. The first loss of water may be due to the small amount of water which is enclosed in the inner spheres of the solid whereas at 400°C the leaving of crystal water is observed, which had obviously been in strong interaction with the inorganic compound. 

The semimicro Kjeldahl-Gunning method (ASTM D-3179 ISO 333) has become a widely used method for determining nitrogen in coal, but there is some doubt about whether or not nitrogen recovery is complete by this procedure. In fact, the fate of nitrogen in the Kjeldahl method depends on its chemical form in the coal, the inorganic compounds added to catalyze the hydrolysis, and the amounts and types of compounds used to raise the boiling point of the mixture.

Acetonitrile (mp, -45°C bp, 81°C) is a colorless liquid with a mild odor. Because of its good solvent properties for many organic and inorganic compounds and its relatively low boiling point,... 

This index lists all compounds appearing in the azeotropic tables. Included are formula, name, standard boiling point, and numbers of the systems in which the compound appears as a component. The inorganic substances are indexed first. 

Thermophysical properties for more than 7,800 chemicals and hydrocarbons are presented in this book for temperature dependent properties. Values for enthalpy of vaporization at normal boiling point are provided for more than 22,000 compounds. The comprehensive coverage includes C1 to C100 organics and Ac to Zr inorganics.
