An apocalyptic story set in the furthest reaches of our planet, in a stark desert landscape where humanity is broken, and most everyone is crazed...

The photoinitiator EHA (isooctyl p-dimethylaminobenzoate, trade name ESCALOL507) is a good UV absorber in the UVB region, and its maximum UV absorption peak is 311nm (ethanol solution). As an anti-ultraviolet active ingredient, it is widely used in sunscreen cosmetics abroad, and the dosage is very large. The US FDA lists sunscreens containing this product ingredient as the first cosmetic recommended by Chemicalbook. At present, with the continuous and rapid development of my country's sunscreen product market year by year, it is necessary to import isooctyl p-dimethylaminobenzoate (photoinitiator EHA) raw materials from abroad every year as an anti-aging agent for industrial products. Therefore, it is of great practical significance to carry out research on the synthesis process of isooctyl p-dimethylaminobenzoate (photoinitiator EHA), and it is also helpful to realize the localization of the product.
