Product Description

Shandong Believe Chemical Pte. Ltd. 4-(Chloromethyl)benzoic acid CAS 1642-81-5 is obtained by oxidation and chlorination of p-xylene. 1. Catalytic oxidation add p-xylene and cobalt naphthenate into the reaction pot, raise the temperature to 90 ℃, inject air, and react at 110-115 ℃ for 20h. Cool to room temperature, filter, wash the filter cake with p-xylene, and dry to obtain p-methylbenzoic acid. 2. Chlorination add chlorobenzene and p-methylbenzoic acid into the reaction pot, heat to 40 ℃, add nitrogen, and stir evenly. When the temperature rises to 60 ℃, stop nitrogen, switch to chlorine, and light at the same time. The temperature reaches 110 ℃ within 1h, and keep it at 110-115 ℃ and continue to pass chlorine for 8h, so that the amount of chlorine passed exceeds the theoretical amount. Then stop chlorine and pass chlorine. Discharge hydrogen chloride from the material. Stop nitrogen and heating, put the material at 90 ℃, place it overnight, filter, wash the crystal with a small amount of chlorobenzene, then wash with a large amount of water, filter and dry to get the finished product.
