White solid photoinitiator as well as preparation method and application thereof

The invention relates to a white solid photoinitiator and a preparation method and application thereof.The photoinitiator is a white cotton-shaped solid, C8 alkyl chains are introduced into molecules, the photoinitiator has better fat solubility and is easy to dissolve in a base material, due to the cotton-shaped fluffy structure, the photoinitiator is more stable in the storage process, and the using performance is not prone to being affected by agglomeration and caking; according to the preparation method, phenol and 1-chlorooctane are taken as raw materials, the photoinitiator is obtained through etherification reaction, acylation reaction, halogenation reaction, cyclization reaction and morpholine substitution reaction, the preparation process is simple, the yield is high, and the photoinitiator has a good application prospect. 本发明涉及一种白色固体光引发剂及其制备方法和应用，所述光引发剂为白色棉絮状固体，分子中引入了C8烷基链，其具有更好的脂溶性，在基料中易溶解，且棉絮状的蓬松结构使得其在储存过程中更加稳定，不易因团聚结块影响使用性能；其制备方法以苯酚和1-氯正辛烷为原料，经成醚反应、酰基化反应、卤代反应、环化反应及吗啉取代反应，得到所述光引发剂，制备流程简单，收率高，具有良好的
