Process for the production of pentaerythritol phosphate alcohol

一种生产磷酸季戊四醇酯醇(PEPA)的方法，所述的方法包括在液相中在至少约100℃的反应温度下和在溶剂存在下磷酰氯(POCl#-[3])与季戊四醇(PE)反应，所述的溶剂为至少被一个卤素原子取代和其常压沸点为约40至约150℃的烷烃，例如1，2-二氯乙烷(亚乙基二氯)。反应压力足以使溶剂处于液相。 A process for the production of pentaerythritol phosphate alcohol (PEPA) comprising reacting in the liquid phase phosphorus oxychloride (POCl3) with p...

Zusammenfassung:	一种生产磷酸季戊四醇酯醇(PEPA)的方法，所述的方法包括在液相中在至少约100℃的反应温度下和在溶剂存在下磷酰氯(POCl#-[3])与季戊四醇(PE)反应，所述的溶剂为至少被一个卤素原子取代和其常压沸点为约40至约150℃的烷烃，例如1，2-二氯乙烷(亚乙基二氯)。反应压力足以使溶剂处于液相。 A process for the production of pentaerythritol phosphate alcohol (PEPA) comprising reacting in the liquid phase phosphorus oxychloride (POCl3) with pentaerythritol (PE) at a reaction temperature of at least about 100° C. in the presence of a solvent which is an alkane substituted with at least one halogen atom and having an atmospheric boiling point of about 40 to about 150° C., e.g., 1,2-dichloroethane (ethylene dichloride). The reaction pressure is sufficiently high to maintain the solvent in the liquid phase.
