您要查找的是不是:
- Thus the term dialkyl carbonate includes, for example, methyl ethyl carbonate. 因此术语二烷基碳酸酯包括,例如甲基乙基碳酸酯。
- It is to be understood that when in this Specification we speak of a dialkyl carbonate and similarly of a dialkyl phenylmalnate, that term does not imply that the two alkyl groups are necessarily the same. 有一点要理解:在说明中我们提到二烷基碳酸酯,相似的我们还提到了二烷基苯基丙二酸酯,这两个术语并不是暗示这两个烷基官能团必须是一样的。
- Biodegradable aliphatic polycarbonate is generally prepared by polycondensation of diols with phosgene or dialkyl carbonate, copolymerization of carbon dioxide with epoxide, and ring-opening polymerization of cyclic carbonates. 生物可降解脂肪族聚碳酸酯一般可以通过二元醇与光气或二烷基碳酸酯的缩合聚合、二氧化碳与环氧化合物的共聚以及环状碳酸酯的开环聚合来制备。 其中,环状碳酸酯的开环聚合是合成生物可降解脂肪族聚碳酸酯的重要方法。

- The use of such “mixed” dialkyl carbonates may give rise not only to similar “mixed” malonates, e.g. the corresponding methyl ethyl phenylmalnate, but also to mixtures of simple malonates. 因此使用这种混合二烷基碳酸酯不仅可能得到相似的丙二酸酯,例如相对应的甲基乙基苯基丙二酸酯,而且可能得到简单丙二酸酯的混合物。
- 7.Thus the term dialkyl carbonate includes, for example, methyl ethyl carbonate. 因此术语二烷基碳酸酯包括,例如甲基乙基碳酸酯。
