Disclosed is a process whereby d-alpha-tocopheryl succinate (TS) can be crystallized in a short period of time by subjecting a fluid TS at particular temperature to a particular rate of shear for a particular time in order to accomplish crystallization. Then, while maintaining the crystallized TS at a temperature less than its melting point, we withdraw the crystallized TS from the region of shear flow. In a preferred embodiment of our process, crystallization is enhanced by use of a particular elongational rate for a particular time.
(ZH) 本发明公开的是可在短的时间内使d-α-琥珀酸生育酚酯(TS)得以结晶的方法,为了完成结晶,在一特定的温度下使流体TS在一特定剪切速率下经历一特定的时间。然后在将结晶的TS保持在低于其熔点的温度下的同时,将结晶的TS从剪切流的区域中取出来。在该方法的一个优选实施方案中,通过使用一特定的时间的特定的伸长速率使结晶作用得到增强。
