制备短链全氟烷基碘
Abstract:
本发明公开了用于制备式(I)的全氟烷基碘的改进的方法。F(CF2CF2)n-1 (I)，其中n为2至3的整数，其中所述改进包括在a)约1∶1至约6∶1的式(III)与式(II)的摩尔比，b)约1至约9秒的停留时间，和c)约450℃至约495℃的温度下，使至少一种式(II)的全氟烷基碘和至少一种式(III)的全氟烷基碘接触。F(CF2CF2)m-1 (II)，F(CF2CF2)p-1 (III)，其中m为大于或等于3的整数，并且p为等于或小于2的整数。
Abstract(English):

An improved process for producing perfluoroalkyl iodides of formula (I) F(CF2CF2)n-I (I) wherein n is an integer from 2 to 3, wherein the improvement comprises contacting at least one perfluoroalkyl iodide of formula (II) and at least one perfluoroalkyl iodide of formula (III) F(CF2CF2)m-I (II) F(CF2CF2)p-I (III) wherein m is an integer greater than or equal to 3, and p is an integer equal to or lower than 2, at a) a molar ratio of formula (III) to formula (II) of from about 1:1 to about 6:1, b) a residence time of from about 1 to about 9 seconds, and c) a temperature of from about 450 DEG C. to about 495 DEG C.
