The effects of various reaction conditions were studied by GC analysis. Reaction time has slight effect on the conversion of acenaphthene. The selectivity of N-phenyl aminoacenaphthene increases with reaction time. Biacenaphthenyls or N-phenyl aminoacenaphthene is in the majority, 77.6% or 90.2% when the molar ratio of AlCl3 to acenaphthene is 1.2 and 2.4 respectively.

GC考察了不同反应条件对苊转化率和产物选择性的影响，时间对苊转化率影响不大，N-苯基氨基苊的选择性随着时间增加而增大；随着AlCl3用量的增加，苊转化率和N-苯基氨基苊的选择性随之增加；AlCl3与苊的摩尔比为1.2和2.4时，产物中联苊和N-苯基氨基苊的选择性分别达到77.6%和90.2%。

Not all of Acer's phones clear this bar.

Acetanilide was annealed at 130℃,it was reached at about 30min.

时，在130℃热处理，约30min时就达到平衡状态。

So if you are the acetate or electric company, you'll need to be as nimble as I am if we are to work together.

所以，如果你是醋酸盐树脂公司或者电力公司的话，你就需要达到和我一样的灵活度，否则我们就无法共事了。

The results showed that the Mulberry fruit surface carried large numbers of yeast but little other mixed fungi; ethanol fermentation reached the peak value in 48h'; before vinegar production the acetification bed breeding took 9~10d, but the vinegar fermentation cycle was only about 24h during production .

结果表明，桑椹果实表面携带有大量的酵母菌而几乎不带其他杂菌，酒精发酵醪除含有大量的酵母菌之外未发现有其他杂菌，酒精度在发酵 48h 时达到高峰；桑椹醋生产前的醋酸菌床培育需要9～10d 时间，投入生产后醋酸发酵周期仅需要24h ；桑椹醋总黄酮含量高达6.68 mg/mL ，对 DPPH 自由基的清除作用远高于山西陈醋、镇江香醋和山楂果醋，具有良好的抗氧化作用；利用桑椹醋自身色素颜色变化可判断酸度测定时酸碱滴定终点。

Through the orthogonal experiment, the optimum condition for tagatose synthesization was determined to be 0.02 mol/L calcium chloride, 30 min, acetum neutralization.

通过正交设计实验优化反应条件，最终确定以0.02 mol/L的CaCl2为催化剂，反应时间30 min，用醋酸中和金属氢氧化物D-塔格糖复合物时，D-塔格糖的产率最高，可达到49.05%。
