General description
多磷酸（PPA）广泛用作各种反应中的酰化和烷基化试剂。它是一种强无机酸，具有优异的脱水性能。
Application
多磷酸可用于合成芳族砜，N-取代的酰胺和 4-氨基二苯甲酮。它也可用于脱水，Fischer-Indole 合成，Beckmann 重排和 Schmidt 重排反应。它可以用作合成各种芳族酮的催化剂。
PPA 可以在从尿素和甲醇合成碳酸二甲酯（DMC）的过程中用作催化剂。它还可作为该过程中产生的氨的吸收剂。PPA 可用于制备二氧化硅负载的多磷酸（PPA-SiO2），一种易于处理、可重复使用的非均相催化剂。

Based on the chemiluminescence (CL) emission generated from the oxidation of ceftriaxone sodium alkali hydrolysate by potassium permanganate in polyphosphoric acid (PPA), a novel determination method for ceftriaxone sodium was developed by using a flow-injection technique. The calibration curve appears
