敌百虫是由三氯乙醛和二甲基磷酸酯经缩合而获得的烷基磷酸酯类化合物。化学纯净的敌百虫是带香味的白色结晶物,而工业品的为灰白色具有强烈气味的混合物。当水温在18—20℃时,工业品的溶解度不低于10%,溶液是稍带白色的透明状乳浊液。增加温度,溶解度将显著增加。敌百虫具有胃毒、接触和一定程度的内吸和熏蒸毒杀作用。其中以胃毒作用最强烈,它比接触作用要
Trichlorfon is an alkyl phosphate ester obtained by condensation of chloral and dimethyl phosphate. Chemically pure trichlorfon is a scent of white crystals, while industrial products are off-white with a strong odor mixture. When the water temperature at 18-20 ℃, the solubility of industrial products of not less than 10%, the solution is a slightly white transparent emulsion. Increase the temperature, the solubility will be significantly increased. Trichlorfon with stomach poisoning, exposure and a certain degree of absorption and fumigation poisoning effect. One of the most intense stomach poisoning, it is more than the role of contact
