- 产品应用2,4,5-涕丁酸(93-80-1)的用途:1,2,4,5-TB作为一种选择性除草剂,主要是由于它在植物体内发生侧键β-氧化而降解为2,4,5-三氯苯氧乙酸(2,4,5-T)而表现出来.2,2,4,5-T和2,4-D一样,在植物体内类似于天然植物激素吲哚乙酸(IAA)的作用,由于它们的参与,打破了体内调节激素的合成和正常水平,同时也影响体内某些酶和蛋白质的合成,从而影响到杂草的新陈代谢,因而对某些杂草显示出选择性很高的除草作用.在低剂量下,由于上述过程在作物体内的发生,2,4,5-TB对作物显示出明显生长调节作用.3,对多数杂草的防除能力比2甲4氨和2,4-D丁酸差,但选择性高.2,4,5-TB亦可作植物生长调节剂.4,钠盐水溶液以水稀释后喷雾.
- 性质描述2,4,5-涕丁酸(93-80-1)的性质:1,纯品为无色结晶,熔点114~115°C.2,其钠盐25°C在水中溶解度20%以上.3,2,4,5-TB在丙酮中溶解度大于10%.

摘要:Our discovery concerns the method of synthesis and the application of new chemical products for plant growing. These new products are polymeric derivatives of low molecular weight plant growth regulators and are characterized by slow release of the auxin from the polymeric carrier. By copolymerisation of allylic esters of the low molecular weight auxins with the acrylic (or the methylacrylic) acid and the following modification of the synthesized co-polymers of acids to their corresponding ammonium salts, water soluble polymeric auxins possesing optimal molecular weight and desirable (high) content of the low molecular weight auxin in the polymer were prepared. The method of synthesis and the final products fulfill the requirements of the preparation technology and of their application respectively. We suggest the application of the new products in agronomy (i.e. treatment of seeds, rootstocks, plants, scions, cutting etc) either by themselves or by combination of them with other chemicals. The chemical structure of the new products we discover is :n n    R = H-, -CH3, Au = auxin residue
