缩醛
Eight acetals(Ketals) were synthesized under the optimal conditions. 在最佳条件下,合成了八个缩醛(酮)化合物。
Do not contact methylene chloride acet (like nail oil) strong acid detergent. 不要接触亚甲基氯化物、丙酮(去指甲油剂)、强酸清洗剂。
If contact with nail oil use alcohol (no contain acet) and then water to clean. 若沾上指甲油请用不含丙酮的清洗剂(如：天那水、酒精)，再用水冲。
This paper reviewed the research development and systhesis of acetals and ketal flavors. 综述了缩醛(酮)反应的研究进展,重点介绍了缩醛(酮)类香料的合成方法。
The hydroxyl groups can be changed into esters, ethers, acetals and ketals, etc. 最常用的羟基保护基可归纳为三类：酯类、醚类和缩醛或缩酮类。
