Reactivity Profile

Simple aromatic halogenated organic compounds, such as 2,6-Dichlorobenzal chloride, are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Method for synthesizing 2, 6-dichlorobenzaldehyde by hydrolysis

The invention discloses a method for preparing 2, 6-dichlorobenzaldehyde by hydrolysis. The method comprises the following steps: heating 2, 6-dichlorobenzyl chloride to 120-160 DEG C, adding a pi complex formed by 0.05-6wt% of a metal salt and benzaldehyde or a benzaldehyde derivative as a catalyst, slowly dropwise adding water with the molar weight equal to that of the 2, 6-dichlorobenzyl chloride, stopping reaction when the content of the 2, 6-dichlorobenzyl chloride is lower than 0.05 wt% to obtain a 2, 6-dichlorobenzaldehyde crude product, and refining to obtain the 2, 6-dichlorobenzaldehyde. 2, 6-dichlorobenzyl chloride is used as a raw material, the used catalyst is the pi complex formed by the metal salt and benzaldehyde, the solubility of the reaction raw material 2, 6-dichlorobenzyl chloride is increased, a homogeneous reaction system is formed, the usage amount is small, a hydrolysis reaction can be initiated at a low temperature, and the reaction is stable. The method has the advantages of mild reaction conditions, high yield, few side reactions and environmental friendliness.
