| titleOfInvention | Improvements in or relating to the manufacture of alklai metal addition products of aromatic hydrocarbons |
| abstract | Alkali metal addition compounds of aromatic hydrocarbons of the naphthalene series are obtained by treating the hydrocarbon with the metal at -80 to + 50 DEG C. in presence of a polyether, or mixture of polyethers as solvent, with a further diluent if desired. According to examples, sodium is reacted with naphthalene in dimethylethylene glycol ether, diethyl ethylene glycol ether, methylal, ethylene glycol methylethyl, methylbutyl, dibutyl and butylauryl ethers, trimethylene glycol dimethyl ether, glycerol trimethyl ether, glycerol dimethyl ethyl ether, methyl and ethyl orthoformate, methyl ethyl carbinol, the formaldehyde derivative of glycol monomethyl ether, dioxane, glycol formal, methyl glycerol formal, and dimethylene pentaerythrite; further, potassium may be reached with naphthalene, a -methyl- and b -methyl-naphthalene, in dimethyl glycol ether, and lithium and sodium likewise in the same solvent; the formation of the product is shown by a green coloration and in the case of sodium and naphthalene it is largely the 1 : 4 addition product. Further polyethers specified include 1 : 2- and 1 : 3- propylene glycol, and further solvents which may be admixed with the polyethers include higher monoethers, hydrocarbons and alkyl sulphides, up to specified maximum concentrations. The alkali metal addition products yield hydrogenated hydrocarbons on treatment with water of alcohol. |
