Abstract

The invention uses lytic agent in phenols to dissolve product of nylon 66. After separating agent in alcohols separates nylon 66 out from dissolution liquid, alcoholic solution of containing 2-benzotriazol-4, 6- phenol diisopropyl benzene is obtained. Using high performance liquid chromatography analyzes content of 2-benzotriazol-4, 6- phenol diisopropyl benzene in product of nylon 66. The invention can pick up agent of anti ultraviolet of 2-benzotriazol-4, 6- phenol diisopropyl benzene from product of nylon 66 conveniently. Features are: good reproducibility of high performance liquid chromatography analysis, and suitable to control quality of product of nylon 66.

Description

technical field [0001] The invention relates to a high performance liquid chromatography analysis method for the content of anti-ultraviolet agent 2-benzotriazolyl-4,6-dicumyl phenol in nylon 66. Background technique [0002] In the processing and manufacturing of polymer material products, in order to meet the needs of different purposes, various additives are added, such as antioxidants, anti-ultraviolet agents, antistatic agents, etc., to enhance the anti-oxidation, anti-ultraviolet, and anti-static properties of the products. 2-Benzotriazolyl-4,6-dicumyl phenol is an anti-ultraviolet agent, which is widely used in polymer materials such as nylon 66. Usually, the content of anti-ultraviolet agent in nylon 66 is determined by the input amount of anti-ultraviolet agent in the process of processing. Due to the heat volatilization and thermal decomposition in the process of processing, the content of anti-ultraviolet agent in nylon 66 is reduced, which directly affects the qu...
