On the pyrolysis of benzalkonium salt ([CH3(CH2)n-N-(CH3)2-CH2-C6H5]+X-, X=Cl or Br) in a sealedglass tube at 250°C, n-alkyldimethylamine{CH3(CH2)n-N-(CH3)2}, n-α-olefine{CH3(CH2)n-2CH=CH2}andbenzylhalide (C6H5·CH2-X) were obtained and identified by I. R. spectrum and G. C. Alkyldimethylamine was also decomposed to n-α-olefine under the same conditions. While in the injection port of gas chromatograph at the same temperature benzalkonium salt was decomposed to alkyldimethylamine and bezylhalide, and n-α-olefine was not detected. The decomposition route of benzalkonium salt was discussed on the above results, and the lipophilic groups of benzalkoniumsalts with the peak of alkyldimethylamine were determined.
