Benzyl chloromethyl ether Use and Manufacturing
It is derived from the reaction of benzyl alcohol, formaldehyde and hydrogen chloride. First mix the benzyl alcohol and formaldehyde solution, cool to 5°C, pass in hydrogen chloride to make the reaction solution saturated, and continue to pass in hydrogen chloride at 10°C. The reactants are separated into layers, the upper layer solution is dried with anhydrous calcium chloride, and the hydrogen chloride is removed under reduced pressure. Then vacuum distillation, collect 96-99 ℃ (1.47kPa) distillate, get the product.
Used as acid protecting group; introducing benzoic acid group and hydroxymethyl group
