The volume ratio of furaldehyde to acetic anhydride is 1∶2; the mole ratio of furaldehyde with anhydrous potassium carbonate is 1.00∶0.54. The best phase transfer catalyst is PEG1000, the mass ratio of PEG1000 with furaldehyde is 4.3%, the reaction time is 11 min, the reaction power of microwave is 260 W. The yield ofα-furanacrylicacid is up to 72.3% under these reaction conditions.

In the absence of organic solvent and phase-transfer reagent, the catalytic oxidation of cyclo- hexene to adipic acid with aqueous 30% hydrogen peroxide can be achieved in the presence of tungstic acid/acidic organic additive.

以钨酸/有机酸性添加剂为催化体系，在无有机溶剂、相转移剂的情况下，催化 30%过氧化氢氧化环己烯合成己二酸。当钨酸∶有机酸性添加剂∶环己烯∶过氧化氢=1∶1∶40∶176(摩尔比，钨酸用量为 2.5 mmol)时，使用有机酸性添加剂考察钨酸的催化性能，结果表明以钨酸/间苯二酚催化氧化环己烯的催化效果最优，反应 8 h 时己二酸分离产率达 90.9%、纯度为～100%；而不使用有机酸性添加剂时，己二酸分离产率只有 72.1%，产品纯度为 96.2%。

We ever reported cellulose is in propyl of Xi of ionic liquid 1-- chloric salt of Zun of 3- methylic Mi (the homogeneous phase acetyl in Am ImC L) converts reaction, falling without activator condition, one pace gets the CA of different DS, get acetone but the CDA[12] of dissolve.

我们曾报道了纤维素在离子液体1-烯丙基-3-甲基咪唑氯盐中的均相乙酰化反应，在无催化剂条件下，一步得到不同DS的CA，并得到丙酮可溶的CDA[12]。

It is probably that there were not Ca〓 channel on the guinea pig sperm PM, because the Ca〓 channel blockers verapamil, nifedipine, diltiazem and D600 promoted acrosome reaction in synchronous and nonsynchronous cultural systems.

豚鼠精子质膜可能无Ca〓通道，因为verapamil、dilliazem和D600等对获能和未获能的精子的顶体反应均具有显著的促进作用。
