Product function:

Hexanoic Anhydride can be used in organic synthesis, synthesis of esters and drugs.

Production Method of Caproic Anhydride:

  • Hexanoic Anhydride can be prepared by reacting n-hexanoic acid with ketene.

  • Cool the n-hexane acid, make it pass through the ketene, and heat the reaction. After the reaction is completed, carry out fractional distillation. The temperature is raised to 220°C within 1 hour, and the low-boiling substances are evaporated under normal pressure conditions.

  • Then collect the distillate at 118-121°C (1.6 kPa) by fractional distillation under reduced pressure to obtain the final product-Hexanoic Anhydride.

Note: The process of this step is provided by look chemical for reference only. The actual production depends on the actual situation.
