The present invention relates to thioxanthone-4-carboxylates, a method for the preparation of the compounds, photoinitiator compositions and use of them as photoinitiators. The compounds of the invention have a structure according to Formula ( I ) below:
in which:
each R1 is independently selected from the group consisting of H, halogen, C1-C12 alkyl, C3-C6 cycloalkyl or C1-C12 alkoxy;
R2 and R3 are independently selected from the group consisting of H, halogen, C1-C18 alkyl, C3-C6 cycloalkyl or C1-C18 alkoxy;
Y is independently selected from the group consisting of C1-C18 alkoxy or small molecular compounds containing 2-6 hydroxyl group;
m is a number from 1 to 6; and
X is
or
wherein R4 and R5 are each independently selected from the group consisting of H, halogen, C1-C6 alkyl; a is a number from 1 to 6; b, d, e respectively represent a number from 1 to 25, c is a number from 1 to 5. The invention provides the compounds with the characters of low extraction, low migration and low volatility and use of them as photoinitiators in photo-polymerization, or package materials of medicine or food. As well, the raw materials of the invention are easily got, and the process of the invention is simple, so thioxanthone-4-carboxylate derivatives are suitable for industrial production.
本发明涉及硫代蒽酮-4-羧酸酯,一种制备该化合物的方法,光引发剂组合物以及将它们用作光引发剂的用途。本发明的化合物具有如下式(I)所示的结构:其中:每个R1独立地选自H、卤素、C1-C12烷基、C3-C6环烷基或C1-C12烷氧基组成的群;R2和R3独立地选自H、卤素、C1-C18烷基、C3-C6环烷基或C1-C18烷氧基组成的群;Y独立地选自C1-C18烷氧基或含有2-6个羟基的小分子化合物;m是1到6的数字;X是或其中R4和R5各自独立地选自H、卤素、C1-C6烷基;a是1到6的数字;b、d、e分别表示1到25的数字,c是1到5的数字。本发明提供了具有低萃取性、低迁移性和低挥发性特性的化合物,并将它们用作光聚合中的光引发剂,或用作药品或食品包装材料。此外,本发明的原材料易于获取,而且本发明的工艺简单,因此硫代蒽酮-4-羧酸酯衍生物适合工业生产。
