8、氢氧化双甘膦,得到草甘膦。2、自产亚磷酸三甲酯的企业采用亚磷酸三甲酯生产工艺生产草甘膦。3、采用亚磷酸二甲酯(膦酸二甲酯)生产工艺生产:亚磷酸二甲酯与甲醛、甘氨酸反应生成草甘膦二甲酯,然后水解得草甘膦。此法有收率高,纯度高的优点,是目前中国生产草甘膦的主要方法。作用机制草甘膦主要是阻碍芳香氨基酸的生物合成,即苯丙氨酸、色氨酸及酪氨酸通过莽草酸途径的合成。它对5-烯醇丙酮酰莽草酸-3-磷酸合酶(EPSP合酶)有抑制作用,该酶可以催化莽草酸-3-磷酸和烯醇丙酮磷酸向5-烯醇丙酮酰莽草酸-3-磷酸(EPSP)的转化,因此草甘膦干扰这一生物合成的酶促反应,导致莽草酸在生物体内的积累。4 此外草甘膦也可

Under UV-vis light, the Pt/N-TiO2 exhibited 5.5 times higher activity than Degussa P25. Various gaseous pollutants were degraded by employing the Pt/N-TiO2 in a
23、 batch reactor. The capability of photodegradation of VOCs under room lights was also proven by the decomposition of gaseous toluene in a continuous reactor using fluorescent lamps (610W). The mechanism of the enhanced activity in degradation of VOCs and potential application were discussed. ? 2011
