Using conditional test, the isobutyraldehyde glycol acetal was synthesized from isobutyraldehyde and ethylene glycol by direct esterification using strong acidic cation exchange resin as catalyst.
运用条件实验法，以异丁醛、乙二醇为原料，强酸性阳离子交换树脂为催化剂，合成了异丁醛乙二醇缩醛产品。
The synthesis of furfural glycol acetal from furfural and ethylene glycol in the presence of ion exchange resin was investigated.
本文研究了在离子交换树脂存在下，由糠醛和乙二醇反应制备糠醛缩乙二醇的工艺条件。
Acetal resin containing boron PHENOL-XYLENE
含硼苯酚二甲苯缩甲醛树脂
The reaction of phenol, xylene& formaldehyde resin with boric acid gets an acetal resin.
苯酚、二甲苯缩甲醛树脂及硼酸反应生成缩醛树脂。
Although the retentive force of acetal resin clasps was in general lower than that of the Co-Cr alloy clasps, it has better flexibility and fatigue resistance with deeper undercut. So acetal resin clasps can be applied in clinical as the meaningful supplements of Co-Cr alloy clasps.
研究结果表明尽管缩醛树脂卡环固位力总体上低于钴铬合金卡环，但它具有更好的弹性和抗疲劳性，完全可以作为对钴铬合金卡环一种有益的补充应用于临床。
