摘要
The use of liquefiable gaseous ether or pressurise of the type methyl or dimethyl (butyl, propyl, ethyl)-ether which function as a solvent (in the liq. state for salts or other organo-metallic elements to give a liq. or gas burning with a coloured frame - the colour depending on the organo-metallic(s) chosen. A method for estimating the content of elements by flame analysis is also claimed. USE/ADVANTAGE - The ether is used as a co-solvent with a gaseous hydrocarbon e.g. butane-propane-isobutane etc. to give one stable gas for introduction into a commercial gas briquette or other form of firelighter. The use of a gaseous co-solvent similar in properties to the hydrocarbon, entrains the colouring action and the yellow colouration (due to incomplete combustion of Co and CO2) is suppressed.
