Study on Refining P-DCB by Watering-Out Crystallization

水析结晶精制对二氯苯研究

The study indicated that the volatilization of P-DCB was very rapid with a high rate and obeyed to the first-rank reactive dynamics equation.

结果显示，雪、水中P-DCB的挥发速率相当迅速，土壤中P-DCB的挥发速率相对较慢，但都服从一级反应动力学方程；

Objective To study the acute toxicity of Para-Dichlorobenzene ( p-DCB) mothball.

目的研究市售含对二氯苯防蛀剂的急性毒性。

When the adding concentration of p-DCB in snow and water was in the range of 0.1~ 100.0 μ g/ g and 0.1~ 100.0 μ g/ mL, the higher the adding concentration, the quicker the volatilization rate and the shorter the half-life.

雪与水中p-DCB在投加浓度分别为0.1~100.0μg/g，0.1~100.0μg/mL范围时，投加浓度越高挥发速率越快，挥发半减期越短。

Under natural conditions, the half-life of p-DCB in snow and water was 2.32~ 3.25 days and 0.76~ 1.20 days, respectively.

在自然条件下，雪与水中p-DCB半减期分别为2.32~3.25d和0.76~1.20d。
