Sun protection mechanism editor
Octyl salicylate with conjugate PI bond, can absorb ultraviolet light, and ultraviolet energy released as heat so as to achieve the aim of sunscreen. Octyl salicylate can absorb ultraviolet ray of 280-300 - nm wavelength, and is known as UVB absorber used in sunscreen makeup. Although octyl salicylate's ultraviolet absorption capacity is weak, but compared to most other sunscreen it's safer and cheaper, and has lower toxicity, so is a commonly used uv absorber.
Methyl salicylate, octanol and sodium methanol were added to a certain proportion in a 1000mL three-mouth bottle, and thermometers, pricking columns and mechanical agitators were installed respectively.Heat the reflux reaction under agitation and collect methanol, the byproduct of the reaction, through the condenser.With the continuous steamed out of methanol, liquid reaction heats up, until the end of 200 ~ 205 ℃ after reaction.Cool to 8 ℃ below, o twice with hot water washing, dry and anhydrous sodium sulfate, with the pump before the first removal boiling isooctyl alcohol and a small amount of methyl ester mixture, and then collect 165 ℃ ~ 168 ℃ / 2.3 kPa fraction for the product.
