Product Description

Ethyl 4-DiMethylaMinobenzoate(EDB) Cas Number is 10287-53-3, a highly efficient amine promoter, often used with free radical (II) photoinitiators, primarily UV cured for paper, wood, metal and plastic surfaces Varnish coatings, inks, adhesives, etc. It can also be used for UV radiation polymerization of single or multiple monomers, and is a good sensitizer, often used in combination with other photoinitiators, to promote both photoinitiation and oxygen to photoinitiator polymerization. Interference effect.
His synthesis is divided into three steps: (1)Ethyl 4-DiMethylaMinobenzoate(EDB) Cas Number 10287-53-3 is thoroughly mixed with the catalyst potassium permanganate under the condition of alkali solution to ensure that the alkali solution is added in sufficient amount, and heating is carried out at the same time, and the reaction temperature is controlled at 60- 70℃ for 30 min before the reaction, stirring was carried out. The amount of alumina powder equivalent to potassium permanganate was slowly added during the stirring process. The total reaction time was controlled to be more than 20 h. After the reaction was completed, the reaction solution was cooled to room temperature. The cooled solution is filtered, and the filtrate is adjusted to neutral or weakly with hydrochloric acid or sulfuric acid. After a large amount of pale yellow precipitate is precipitated, it is filtered again to obtain crude p-dimethylaminobenzoic acid; crude p-dimethylaminobenzoic acid Re-dissolved in an ethanol solution and recrystallized to obtain p-dimethylaminobenzoic acid;
(2) adding the benzene and ethanol solution to the p-dimethylaminobenzoic acid obtained in the step (1), stirring well, then adding a small amount of concentrated sulfuric acid, starting to heat and stirring until heating to boiling, until the reaction is complete After the water vapor is generated, the reactor is sealed, the heating temperature is controlled at 40-50℃, and the reaction is continued for 0.5-1 h, then the heating is stopped and cooled to room temperature;
The solution cooled to room temperature is repeatedly washed repeatedly with saturated brine and distilled water until it is washed to neutrality to obtain Ethyl 4-DiMethylaMinobenzoate(EDB) Cas Number 10287-53-3,
