三聚乙醛

以三聚乙醛和异丁醇为原料，合成了二异丁基乙缩醛。

Diisobutyl acetal was synthesized by the condensation of paraldehyde and iso-butyl alcohol .

采用直接进样大口径毛细管柱气相色谱法，可同时测定聚酯废气中乙烯、乙醛、乙酸、2甲基1,3二氧戊环、三聚乙醛等污染物含量。

Ethylene , acetaldehyde , acetic acid , 2 methyl 1,3 dioxolane , paraldehyde and so on in polyester exhaust gas can be directly determined by gas chromatography with wide bore capillary column at the same time .

三聚乙醛氯化合成二氯乙醛三聚乙醛解聚制备乙醛研究

Study on the preparation of acetaldehyde from depolymerization of paraldehyde

母液经浓硫酸作用，在温度45～65℃下，解聚副产物三聚乙醛回收乙醛。

In the presence of concentrated sulphuric acid the mother solution was heated under the temperature between 45 ℃ and 65 ℃ to depolymerize paraldehyde for recovering acetaldehyde .
