matters needing attention

Homosalate is a UV UVB sunscreen agent, which belongs to chemical sunscreen agent and can absorb UVB 295-315 bands. However, some studies have shown that Homosalate has a weak effect on hormones and produces toxic metabolites. The amount required shall not exceed 10%.

preparation

Add 10.0g of methyl salicylate and 14.0g of 3,3,5-trimethylcyclohexanol into a 250ml three necked bottle, mix well, add 5.0g of potassium carbonate, heat up to 120-130 ℃, react with Chemicalbook for 10h, and the conversion rate of methyl salicylate monitored by gas chromatography is 85.6%. By vacuum distillation, 12.2g of colorless and transparent fumaric ester was obtained with a yield of 70.8% and a GC purity of more than 99%.
