查询词典 naphthalate

Dimethylnaphthalene is an ideal raw material of the production of polyethylene naphthalate. It is an important task to obtain 2,6-dimethyinaphthalene in low cost.

2，6-二甲基萘是制备高性能聚酯-聚对萘二甲酸乙二醇酯最理想的原料，如何低成本地获得2，6-二甲基萘已成为一项重要的课题。

Dimethylnaphthalene (2,6-DMN) is a potentially useful raw material for production of polyethylene naphthalate, polybutylene naphalate and liquid crystalline polymers with superior properties. How to industrialize the process of producing 2,6-DMN is getting more and more studied in the world recently.

2，6-二甲基萘(2，6-DMN)是合成新型聚酯树脂聚萘二甲酸乙二醇酯和聚萘二甲酸丁二醇酯以及液晶高分子聚合物的重要原料，所以将2，6-DMN的生产工业化最近几年成为国内外研究的重点。

Poly(ethylene-2,6,-naphthalate) is a newly developed polyester. The chemical structure of PEN can be described by replacing the benzene ring in poly with the stiffer naphthalene ring.

聚萘二甲酸乙二酯是一种近年来获得较大发展的高性能聚酯材料，其分子结构与聚对苯二甲酸乙二酯相类似，可看作是由PET链中苯环由刚性更大的萘环所替代的产物。
