The pentaerythritol is a wide used chemical product in the commerical run. At present, the recovery ratio is only 91 percent in producing the pentaerythritol in external and internal. So recovering the pentaerythritol and the sodium formate from the accessory substances of the pentaerythritol is very important to enviroment protection and economy. By the experiment, we obtain the better department effect with the way of extraction from producing the accessory substances of the pentaerythritol in a factory of JCIC.
