The Vapor Pressures of Forty-one Fluorine-containing Organic Compounds¹

Abstract

A mechanism involving hydrogen bonding with fluorine attached to carbon was proposed to explain acid catalyzed reactions of alkyl fluorides.The reaction of the benzyl fluorides with sodium iodide in acetone was found to be extremely slow.Ithaca, X. Y.

“…Using vapor pressure and reduced boiling point data from several other studies 24,[232][233][234][235][236][237][238] gives eq 24 for the temperature range from 0 to 147°C log p(Torr) ) 9.4((0.1) -2700( (40) T(K) (24) This expression is plotted with the data in Figure 14, showing good agreement between the various data sources. Note that the ambient boiling point is not shown in the figure but was included in the analysis.…”

“…231 One study reports that the vapor pressure of isopropyl methylphosphonofluoridate obeys eq 23 over the temperature range from 0 to 60 °C232 log p(Torr) ) 9.8990 -2850.9 T(K) (23) This study does not report individual data points. Using vapor pressure and reduced boiling point data from several other studies 24,[232][233][234][235][236][237][238] gives eq 24 for the temperature range from 0 to 147 °C log p(Torr) ) 9.4((0.1) -2700(( 40)…”

“…The boiling point at ambient pressure is reported in various data compilations as 147 and 158 °C, and the melting point is reported to be −56.3 °C . One study reports that the vapor pressure of isopropyl methylphosphonofluoridate obeys eq over the temperature range from 0 to 60 °C This study does not report individual data points. Using vapor pressure and reduced boiling point data from several other studies ,− gives eq for the temperature range from 0 to 147 °C This expression is plotted with the data in Figure , showing good agreement between the various data sources.…”

Chichibabin Reactions with Phenylacetaldehyde. II1

“…This proves that the two carboxyl groups in the water-soluble acid are vicinal. Since one of these groups is alpha and since the 3-phenylpyridinecarboxylic acid isolated in this oxidation undoubtedly resulted from decarboxylation of the dicarboxylic acid, it follows that the latter acid is 5-phenylquinolinic acid (7) Pyridine 2-and 4-carboxylic acids decarboxylate much more readily than the 3-acids, cf. ref.…”

3-Aminodibenzoselenophene and its derivatives

“…ß-Fluoroethyl N-8-dibenzoselenyl carbamate. The same procedure was followed as for the preparation of the preceding carbamate except that ß-fluoroethyl chlorocarbonate (23,24) was used. Crystallization from heptane gave 3.1 g. (92%) of colorless needles, m.p.…”
