1,4-Dioxane (14DX) is classified as a probable human carcinogen by the US Environmental Protection Agency (EPA), and it has toxic effects on the kidney and liver. EPA's Health Advisory Level (HAL) for 14DX is 0.35 micrograms per liter (渭g/L). Accordingly, several states have lowered...
In the aqueous extract of the naturally occurring surfactant, the condensation reaction of aromatic aldehydes with Meldrum’s acid works well to afford 3-carboxycoumarins and 5-benzylidene-2,2-dimethyl-1,3-dioxane-4,6-dione derivatives via Knoevenagel condensation. The reaction with 20...
