The synthesis of amino acids behind shock waves in methane, ethane, ammonia, and water vapor was further investigated. Aldehydes and HCN are formed separately in the non-homogeneous gas during the high temperature period and recombine with ammonia during the thermal quench period, to form chi-amino nitriles. The chi-amino nitriles are either hydrolyzed by excess water vapor during the quench period or emerge as such after the reaction is completed. A combined gas chromatograph-mass spectrometer analysis of the reaction product showed identical amounts of D and L amino acids, thus confirming the absence of contaminants. Thunder shock waves were shown to be a suitable source of energy for the production of amino acids.
对甲烷、乙烷、氨和水蒸气中冲击波后氨基酸的合成进行了进一步研究。在高温阶段,醛和HCN在非均相气体中分别形成,并在热猝灭阶段与氨重新结合,形成χ-氨基腈。χ-氨基腈在猝灭阶段要么被过量的水蒸气水解,要么在反应完成后原样出现。对反应产物进行的气相色谱-质谱联用分析表明,D型和L型氨基酸的含量相同,从而证实不存在污染物。雷电冲击波被证明是产生氨基酸的合适能量来源。
