N,N'-Bis(4-ethoxycarbonylphenyl)-N-benzylformamidine Usage And Synthesis

Description

N, N'-bis(4-ethoxycarbonylphenyl)-N-benzylformamidine is an important ultraviolet absorber. Adding this ultraviolet absorber to the synthesis process of various organic materials such as plastic products, resin products, cosmetics, fuels, textiles, etc. can avoid the destruction of the physical properties of the synthetic products caused by the photodegradation of ultraviolet rays (such as product discoloration, fading, or brittleness and cracking).

Uses

N,N'-Bis(4-ethoxycarbonylphenyl)-N-benzylformamidine is mainly used as an ultraviolet absorber.

Synthesis

Under stirring, add 200g of N, N-dimethylformamide (DMF), 90g of 99% pure N, N'-bis(4-ethoxycarbonylphenyl)formamidine (0.262mol), 61g of potassium carbonate (0.44mol) and 48g of benzyl chloride (0.38mol) to the reaction device in sequence. Slowly raise the temperature to 45℃ and keep the temperature for 24h. After the reaction is completed, add the reaction solution into the water while hot and filter to obtain crude N, N'-Bis(4-ethoxycarbonylphenyl)-N-benzylformamidine.
