To prepare N- (2-hydroxybenzyl) -1,2-dihydroxybenzylamine, the method is as follows:
First take an appropriate amount of 2-hydroxybenzaldehyde, place it in a clean reaction vessel, use alcohol as solvent, often ethanol is preferred, because its solubility and reactivity are suitable. Another equivalent of 1,2-dihydroxyaniline is slowly poured into the above solution containing 2-hydroxybenzaldehyde. During this process, a low temperature environment, about 0-5 ° C is appropriate, so as to facilitate the smooth progress of the reaction and reduce the occurrence of side reactions.
Then, add an appropriate amount of acid as a catalyst, such as acetic acid, in an amount of about 5% - 10% of the total reactants. Gently stir to make the reactants fully mixed and contacted, and the reaction gradually begins. This reaction takes a long time, about 12-24 hours. During this period, stirring should be continued, and the color change of the reaction solution should be observed regularly.
After the reaction is completed, pour the reaction solution into a large amount of ice water, and it can be seen that there is precipitation. This precipitation is the crude product of N- (2-hydroxybenzyl) -1,2-dihydroxybenzylamine. The precipitation is collected by filtration and washed with cold water several times to remove impurities.
After washing the crude product, then purify it by recrystallization. Select a suitable solvent, such as ethanol-water mixed solvent, and prepare it in an appropriate proportion. Dissolve the crude product in it, heat it until it is completely dissolved, then cool it slowly, and control the cooling rate, about 5-10 ° C per hour. When the crystals are fully analyzed, filter again, collect the crystals, and dry at low temperature, a pure N - (2-hydroxybenzyl) -1,2-dihydroxybenzamine product can be obtained.

N- (2-hydroxybenzyl) -1,2-dihydroxybenzyl requires attention to many key matters during storage and transportation.
First, this substance is extremely sensitive to temperature and humidity. Due to its chemical structure, high temperature can easily cause it to decompose and deteriorate, and high humidity may cause moisture decomposition, which affects quality and performance. Therefore, it should be stored in a cool and dry place. The warehouse temperature should be controlled at 15-25 ° C, and the relative humidity should be maintained at 40% -60%. When transporting, it is also necessary to do a good job of temperature and humidity control, such as choosing a means of transportation with temperature control and moisture protection facilities.
Second, N- (2-hydroxybenzyl) -1,2-dihydroxybenzyl has certain chemical activity and is easy to react with some substances. Be sure to avoid co-storage and co-transportation with strong oxidants, strong acids, strong bases, etc. Because of its exposure to strong oxidants, or cause violent oxidation reactions, or even explosions; in case of acid and alkali, it may also cause structural changes and lose its original efficacy. During storage and transportation, ensure effective isolation from these substances.
Third, this substance is more sensitive to light. Light will accelerate its chemical reaction, resulting in decomposition or denaturation. When storing, it should be placed in a dark container or package, and the warehouse window should be shaded with light-shielding materials. During transportation, vehicles should also take shading measures, such as covering with dark tarpaulin.
Fourth, N- (2-hydroxybenzyl) -1,2-dihydroxybenzyl chemicals, storage and transportation must follow relevant regulations and standards. Operators should be professionally trained to be familiar with their characteristics and safe operation methods. Storage sites should be equipped with corresponding emergency treatment equipment and protective equipment, and transportation vehicles should be clearly marked with hazards.
