文献中报导了用氯乙烯二氯硼烷(HClC=CHBCl_2)作为硼同位素激光分离丁作物质的前景。这些文章指出,氯乙烯二氯硼烷分子在CO_2激光场中有选择地离解为化合价饱和的Bal_3和乙炔碎片。然而,我们进行的继续研究表明,在离解产物中,除了上述碎片外,还存在着元素硼。已经发现,如果使激光与物质的相互作用池失去密封性,则在作用池内表面和通光光学元件上逐渐出现一层白色涂层。由红外光谱测量会得到硼酸(H_3BO_3)的清晰吸收峰。从这个实验事 The literature reports the use of vinyl chloride dichloroborane (HClC = CHBCl2) as a boron isotope laser for the separation of butane-containing material. These articles point out that vinyl chloride diborane molecules are selectively dissociated into valence-saturated Bal_3 and acetylene fragments in the CO_2 laser field. However, further studies conducted by us show that elemental boron is present in the dissociation products in addition to the above fragments. It has been found that if the interaction pool of laser light with the material loses its seal, a white coating gradually develops on the inner surface of the active bath and on the light transmitting optical element. Measured by infrared spectroscopy will get a clear absorption peak of boric acid (H_3BO_3). From this experimental thing
