2,4,5-T 是新的植物刺激素和杀草除莠剂,学名叫2,4,5三氯苯酚代乙酸,或2,4,5三氯苯氧基乙酸,简称2,4,5-T。我们现在的制法是利用废品六六六(γ-六六六提出后残留的80%以上没有杀虫效力的α-六六六)作原料,经过水解、氯化等手续而合成的。华北农业科学研究所已在1954年试制成功,经过进一步研究,改良制造方法,成本显著降低,并可大量制造。2,4,5-T 是白色结晶体,熔点153℃,可以溶解在一般的有机溶剂里,在水内溶解度不大,对人畜无害。(但2,4,5-T 的衍生物如酯类,对温血动物是
2,4,5-T is a new phytohormones and herbicides herbicide, called 2,4,5 trichlorophenol acetic acid, or 2,4,5 trichlorophenoxy acetic acid, referred to as 2,4 , 5-T. Our current system of law is the use of waste six hundred sixty-six (γ-sixty-six sixty-six after the proposed non-pesticidal residues of more than 80% α-666) as raw materials, after hydrolysis, chlorination and other procedures and synthesis. North China Institute of Agricultural Sciences trial in 1954 has been successful, after further research and improvement of manufacturing methods, the cost significantly reduced, and can be mass-produced. 2,4,5-T is a white crystalline, melting point of 153 ° C, can be dissolved in the general organic solvents, solubility in water is not large, harmless to humans and animals. (However, 2,4,5-T derivatives such as esters, the animals are warm-blooded
