Just to add to this.....currently in the lab trying to reduce the solvent content of a litre of solution made to pH 10 with ammonium hydroxide solution. During evaporation some Al foil hit by the gas turned an nice black colour and smelt nicely of NH3. No time or reason to analyse it but while looking for the reaction I found this forum.....hope it helps in any kind of small way. Also John...if something is labeled 'Nujol' then one can refer to it as Nujol...if something is labeled as 'Borax' one can refer to it as Borax. This solution is labeled 'Ammonium Hydroxide Solution' hence that is how I shall refer to it. If op had said 'I mixed ethylene with...' would you have said 'Ethylene doesn't exist!! I know only of Ethene!!' of course not. Stop being a tool.
