HCN、H_2S、PH_3、N_2-NH_3与CH_4-H_2O气体混合物的前生物分子合成

Electric Discharge of the Gas Mixtures of HCN, H2S, PH3, N2-NH3 and CH4-H2O——Simulating Prebiotic Synthesis

原始大气反应生成的HCN部分按Strecker反应合成氨基酸,其余随降雨进入水体。由于气液平衡,HCN可重返大气层参与由放电与太阳辐射引发的化学过程。气相中分子扩散迅速、无笼效应,故生物分子的合成较液相中更有效。本文验证了这一过程,并研究了CH_4、H_2S、HCN等在合成生命分子中的作用。 1

This paper reports the results of the simulating prebiotic syntheses with the HCN-H2O, HCN-CH4-H2O, HCN-H2S-CH4-H2O, CH4-N2-NH3-H2O and CH,-N2-NH3-PH3-H2O gas mixtures. The fact which HCN can go back to atmosphere from water bodies has been further confirmed. The experimental results show that HCN is an important intermediate to synthesize biomolecules and that methane is responsible for the formation of the various skeletons of amino acids. The catalytic behaviour of hydrogen sulphide and phosphine on the prebiotic synthesis has been found.
