TetraChloroaluminate, sodium

Morozov and Morozov [32] have also investigated the temperature dependence of the pressure and composition of the vapors and confirmed that the vapors contain aluminum chloride as well as sodium tetra-chloroaluminate. This could be shown experimentally by condensing the vapors which occurred in two zones. In a temperature range from 600 to 800 °C the pressures of A1C13 and NaAlCl4 over sodium tetrachloroaluminate are quite similar they rise from about 10 mm Hg at... 

Molten sodium tetrachloroaluminate (a 1 1 mixture of NaCl and AICI3) is a good reaction medium for the Friedel-Crafts acylation reaction given in fig. 3.3 (Wade et al., 1979). Whereas the classical procedure for the synthesis of 1-indane from 3-phenylpropanoic acid consists of three reaction steps with a total reaction time of ca. six hours (Gattermann et al., 1982), the molten salt reaction is finished in five minutes and gives an even better yield (Wade et al., 1979). 

Tungsten dichloride [13470-12-7], WC12, is an amorphous powder. It is a cluster compound and may be prepared by the reduction of the hexachloride with aluminum in a sodium tetrachloroaluminate melt (11).

One of the early examples of the use of sodium tetrachloroaluminate in intramolecular Friedel-Crafts acylation reactions involved the reaction shown in equation (49), in which P-(3-acenaphthoyl)propanoic acid was converted into perisuccinoylacenaphthene. The formation of the benzosuberanone ring system is particularly easy when electron-releasing substituents are present on the benzene ring. Under those cir-...

Xanthones.—An efficient and convenient method of preparing xanthone in 99% yield is to heat o-phenoxybenzoic acid for 20 minutes at about 155 °C in molten sodium tetrachloroaluminate, obtained by fusing sodium chloride and aluminium chloride. Xanthones (283) were formed by cyclization of diphenyl ethers such as (282), which were prepared by addition of p-cresol to the quinone esters (281) followed by reductive methylation. ... 

Variations of the sodium/sulphur battery include systems with sodium/beta-alumina/sodium tetrachloroaluminate/nickel chloride or iron chloride. The early results are encouraging and the system suffers less from the problems of the sulphur electrode, such as rechargeability, high vapour pressure, various polysulphide formations etc.
