Beschreibung
Zusammenfassung:	A one-step process for preparing chlorowax NO.70 uses chlorine gas or liquefied chlorine and paraffine as raw materials and carbon tetrachloride as solvent, and includes such steps as photochlorination reaction at 65-75 deg.C to generate mixed liquid of chlorowax No.70, washing in water, neutralizing acid with alkaline solution, layering separation, removing salt solution, and reduction distilling to remove CCl4 and H2O. It features low water content less than 1%, simple process and low cost.
