无水醋酸

Result: Xinhuang Tablet had very significant inhibition on acute and chronic inflammation in model of ear edema induced by croton oil in mice, paw swelling induced by carrageenin in rats, granuloma induced by cotton pellet in rats and very significant analgesic effect on thermal and chemical stimulation in model of writhing body response induced by acetic acid in mice and tail flicking in rats.And at the same doses, Xinhuang Tablet hadn't significant difference from ig administration.

结果：新癀片外涂给药对小鼠耳肿、大鼠角叉菜胶足肿、棉球肉芽肿等急、慢性炎症有非常显著的抑制作用；对大、小鼠水浴甩尾、小鼠醋酸扭体等温热刺激、化学刺激引起的疼痛有非常显著的镇痛作用，且在相同剂量下，外涂给药和ig给药的作用无明显差异。

During the reaction,the bromide component has been converted to catalytically inactive benzylic bromide.In pure acetic acid medium,the "catalyst failure" occurs owing to the formation of benzylic bromide while in acetic acid-water medium,the solvolysis of benzylic bromide by water maintains the catalytic activity to some extent.

反应过程中溴组分会转变为无活性的苄溴，在纯醋酸溶剂中，催化剂会因苄溴的形成而发生催化剂失活现象；在醋酸-水混合溶剂中，由于水对苄溴的溶剂化作用会使苄溴还原为溴离子，一定程度上保持了催化剂活性；并且在一定范围内，含水量的提高有益于生成醛选择性的提高，研究表明，将混合溶剂的初始含水量控制在5-10wt。

The acetate bicyclic guanidine has the above structure and is synthesized by a direct reaction of bicyclic guanidine and acetic acid in a catalyst-free aqueous solution.

所述的醋酸双环胍具有如上结构，是由双环胍与醋酸在无催化剂、水溶剂中直接反应合成。
