Preparation method of 4-formylbenzoic acid

The invention provides a preparation method of 4-formylbenzoic acid, and the method comprises the following steps: by using 4-methylbenzoyl chloride as a raw material, performing chlorinating to obtain 4-chloromethylbenzoyl chloride, performing hydrolyzing to obtain 4-chloromethyl benzoic acid, and reacting with urotropine to obtain 4-formylbenzoic acid. The method provided by the invention is simple in process, does not need special equipment and is relatively low in cost; moreover, the method provided by the invention is relatively high in product yield and purity, and large-scale industrialproduction is easy to realize. The result of the embodiment shows that the yield of each step of the preparation method of the 4-formylbenzoic acid provided by the invention is greater than or equalto 90%, and the purity of the finally obtained 4-formylbenzoic acid is greater than or equal to 99.7%.

Ferric(III) Chloride Catalyzed Halogenation Reaction of Alcohols and Carboxylic Acids Using α,α-Dichlorodiphenylmethane

A new method for chlorination of alcohols and carboxylic acids, using α,α-dichlorodiphenylmethane as the chlorinating agent and FeCl3 as the catalyst, was developed. The method enables conversions of various alcohols and carboxylic acids to their corresponding alkyl and acyl chlorides in high yields under mild conditions. Particulary interesting is the observation that the respective alkyl bromides and iodides can be generated from alcohols when either LiBr or LiI are present in the reaction mixtures.
