摘要

实验研究了对苯二甲酸双(2‐羟乙基)酯的结晶过程。优化后的对苯二甲酸双(2‐羟乙基)酯晶体的中位粒径(D50)为1300µm，晶体习惯良好，直径跨度从优化前的11.48减小到优化后的1.72。结果表明，晶体两端有更多的氧原子暴露在晶体表面，这使得晶体易于与游离的对苯二甲酸双(2‐羟乙基)形成氢键。因此，两端的晶体表面生长最快，最终趋于消失。

Optimization of the Crystallization Process of Bis(2‐hydroxyethyl) Terephthalate

The crystallization process of bis(2‐hydroxyethyl) terephthalate is experimentally investigated. The optimized crystals of bis(2‐hydroxyethyl) terephthalate have the median particle size (D50) of 1300 µm and a perfect crystal habit, and their diameter span reduces from 11.48 (before optimization) to 1.72 (after optimization). The results show that more oxygen atoms at both ends of the crystal are exposed to the crystal surfaces, which make it easy to form hydrogen bonds with free bis(2‐hydroxyethyl) terephthalate. Therefore, the crystal surfaces at both ends grow fastest and tend to disappear eventually.

期刊介绍： The journal Crystal Research and Technology is a pure online Journal (since 2012). Crystal Research and Technology is an international journal examining all aspects of research within experimental, industrial, and theoretical crystallography. The journal covers the relevant aspects of -crystal growth techniques and phenomena (including bulk growth, thin films) -modern crystalline materials (e.g. smart materials, nanocrystals, quasicrystals, liquid crystals) -industrial crystallisation -application of crystals in materials science, electronics, data storage, and optics -experimental, simulation and theoretical studies of the structural properties of crystals -crystallographic computing
