A new powdery ammonium nitrate fuel oil explosive was produced to solve the problems of complicated production process and low explosion energy. The explosive was made of ozocerite,surfactant,gelatinizer and water, which were made into slurry mixed solution at 105-110 ℃, and was dehydrated from -0.07 MPa to -0.09 MPa.

为解决当前粉状铵油炸药生产工艺复杂，爆炸能量低的难题，在105～110 ℃将硝酸铵与地蜡、表面活性剂、吸附剂和水混溶制成浆状混合液，并在真空度为-0.07～-0.09 MPa压力下脱水干燥，研磨过筛，得到粉状铵油炸药。

It is indicated that the syneresis of xanthan-chromium gel system can be described by means of first-order reaction.

Therefore esterification crosslinked reactionbetween polyearboxylic acid and wood can be quantitatively determined.According toexperiment results of stereoscopic configuration choices by crosslinking agents,crosslinkingreaction between model of reaction intermediate and wood,and the intermediate characteristic incrosslinking reaction,crosslinking reaction intermediate was proofed.We can infercrosslinking reactions between polycarboxylicacid and wood want through a mechanism of twosteps reaction process,the first cyclic anhydrides were formed as intermediates by dehydratingbetween hydroxyls in polycarboxylic acids,second esters were occurred by substitution reactionbetween wood hydroxyls and cyclic anhydrides.

从而可全面定量表征木材与多元羧酸类化合物的酯化交联反应；依据交联剂立体构型选择性、反应中间体模型物与木材的交联反应和交联反应中间体的波谱特征实验结果，证实了交联反应中间体，因此可以推测：多元羧酸类化合物与木材化学组分的交联反应是经历两步反应的机理，首先多元羧酸中相邻羧基的羟基之间脱水形成五元环酸酐中间体，然后木材的羟基与酸酐发生亲核取代反应形成酯。
