Ethylene glycol dealdehyde catalytic resin

Thread Content

Instruction Manual for ZGCD552 Catalytic Resin I. Introduction ZGCD552 is a catalytic resin specifically developed by Zhengguang for use in ethylene oxide/ethylene glycol production facilities. It possesses specific particle size, specific specific surface area, specific pore size, and specific strength, and is designed for the removal of aldehydes from ethylene glycol. It plays a significant catalytic role in the condensation reaction between aldehydes and ethylene glycol, enabling the formation of ethylene glycol dialdehyde derivatives; this process reduces the formaldehyde content in the product and improves its quality.
