Synthesis method
It is obtained by the esterification of p-toluenesulfonyl chloride and ethanol. Add p-toluenesulfonyl chloride to absolute ethanol and heat to dissolve. in10-12℃Start slowly adding sodium hydroxide solution dropwise, the temperature does not exceed 15℃, measured every half hour1timespH Value, keep9.3-9.7reaction4h. Add ice water and cool to0℃, precipitation crystallization. Filter and dry to obtain ethyl p-toluenesulfonate.
Purpose
Used in organic synthesis as an ethylating agent, used in the pharmaceutical industry to produce benzyl ammonium bromide, and also used as photosensitive materials intermediate. This product is a toughening agent for acetate fiber.
