Synthesis method
1. Introduction to production methods
First mix dry bromine and newly steamed n-hexanoic acid, carefully add phosphorus trichloride, and heat to 65-70℃, the reaction releases a large amount of hydrogen bromide,5-6h ; mso-ascii-font-family: ‘Times New Roman’; mso-hansi-font-family: ‘Times New Roman'”>and then warm it up to 100℃. The obtained product is distilled under reduced pressure and collected132-140℃（2kPa) fraction to obtain the product2-Bromohexanoic acid, yield83-89%.
