Abstract

The invention belongs to the technical field of resin evaluation, and mainly relates to an evaluating method for resins in a phenol refining process. The evaluating method mainly relates to evaluation of adsorption performance of two resins. Firstly, the total ion-exchange capacity of each resin is measured, and then the adsorption performance of each of the resins is evaluated by utilization of static adsorption and dynamic adsorption methods. A method combining headspace solid-phase microextraction and gas chromatography is utilized for measuring impurity contents in phenol in the whole evaluating process. The evaluating method is simple in operation and comprehensive in applications, can be used for evaluation of all resins in industrial applications, and has a good using prospect in the field of fine chemicals.

Description

technical field

[0001] The invention belongs to the technical field of resin evaluation, and mainly relates to a method for evaluating resin in the process of refining phenol. Background technique

[0002] Phenol, also known as carbolic acid, is an important basic organic raw material in chemical production and is widely used in various fields such as synthetic fibers, phenolic resins, medicines and pesticides. At present, more than 90% of the world's phenol is synthesized by the cumene oxidation method, which is easy to operate, has a high yield, and can co-produce acetone. However, in the production process, this method produces a variety of organic impurities that are difficult to remove, which seriously affects the purity and color of phenol, and also brings many difficulties to subsequent production, directly affecting the value of phenol products.

[0003] Phenol refined special resin is specially developed to absorb organic impurities in the production process of phe...
