P4O10是由4个磷氧四面体通过共用角项而联接起来的立体稠环结构．P4O10对水有很大余力，极易吸水，与水反应剧烈，放大量热，事实上，P4O10吸水并不能立即转变成磷酸，这种反应很慢，且是分步进行的，各步变化可用结构反应式表示为：由此可见，P4O10的水解产物同用水量有关．根 P4O10 is a three-dimensional fused ring structure joined by four phosphotetrahedra through a common angle term. P4O10 has a lot of water on the water, it is very easy to absorb water, reacts violently with water, and heat is amplified. In fact, water absorption of P4O10 does not immediately turn into phosphoric acid. This reaction is very slow, and it is a step-by-step process. Structural reaction formula is expressed as follows: It can be seen that the hydrolysis product of P4O10 is related to the amount of water used. root
