To prepare N- (2,6-diethylphenyl) -1,2-naphthalimide, the following methods can be used:
First, use 1,2-naphthalic anhydride and 2,6-diethylaniline as raw materials. First, take an appropriate amount of 1,2-naphthalic anhydride and place it in the reactor, add a certain amount of high-boiling organic solvent such as N-methylpyrrolidone (NMP), heat up and stir to dissolve it. When the temperature is stabilized at 150-180 ° C, slowly put in 2,6-diethylaniline, and the molar ratio of the two is preferably 1:1.1-1:1.3. After putting in, keep this temperature for 6-8 hours. After the reaction is completed, the reaction solution is poured into a large amount of water, solids are precipitated, filtered by suction, and the filter cake is washed several times in hot water to remove unreacted raw materials and by-products. After drying, the crude product is obtained. After recrystallization, an appropriate solvent such as ethanol-water mixed solvent can be selected to obtain N - (2,6-diethylphenyl) -1,2-naphthalimide with high purity.
Second, it is prepared from 1,2-naphthalenyl dicarboxyl chloride and 2,6-diethylaniline. At a low temperature of 0-5 ℃, 1,2-naphthalic anhydride and thionyl chloride are mixed in a molar ratio of 1:1.5-1:2, and an appropriate amount of catalyst such as N, N-dimethylformamide (DMF) is added. When the reaction is 3-5, 1,2-naphthalic acid chloride can be obtained. At the end of the reaction, the excess sulfoxide chloride is removed by reduced pressure distillation to obtain a crude product of 1,2-naphthalic acid chloride. Take another 2,6-diethylaniline, dissolve it in an appropriate amount of dichloromethane, place it in an ice bath, add dropwise the dichloromethane solution of the above-mentioned 1,2-naphthalenedioyl chloride, and the molar ratio of 1,2-naphthalenedioyl chloride to 2,6-diethylaniline is 1:1:1.1. After the dropwise addition is completed, the reaction at room temperature is 4-6. The reaction solution is washed with dilute hydrochloric acid, saturated sodium bicarbonate solution, and water in sequence, dried with anhydrous magnesium sulfate, the solvent is evaporated, and the target product is separated by column chromatography.

After the reaction, it is cooled, the liquid is separated, the organic phase is dried with anhydrous sodium sulfate, the solvent is evaporated, and the residue is purified by silica gel column chromatography to obtain N- (2,6-diethylphenyl) -1,2-naphthalimide.

N- (2,6-diethylphenyl) -1,2-benzoyl requires attention to many key matters during storage and transportation.
First, the properties of this substance may change due to environmental factors, so the storage place should be selected in a cool, dry and well-ventilated place, away from fire and heat sources. Humidity can easily cause reactions such as hydrolysis, and high temperature or direct light can also accelerate its deterioration, affecting quality and performance.
Second, due to its chemical activity, it must be stored separately from oxidants, acids, bases, etc., and must not be mixed. Contact with these substances may cause violent chemical reactions, or even cause ignition and explosion, threatening safety.
Third, the storage container needs to be made of suitable materials to ensure good sealing. It is crucial to prevent leakage. Leakage not only wastes materials, pollutes the environment, but also may cause safety accidents due to volatile gases. And the container should have a certain strength to resist external forces such as vibration and collision during transportation.
Fourth, the transportation process must be stable to avoid severe bumps and collisions. Transportation vehicles should be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment to prepare for emergencies. Transportation personnel also need to be professionally trained and familiar with the chemical characteristics and emergency response methods.
Fifth, whether it is a storage warehouse or a transportation vehicle, clear warning signs should be posted to indicate its dangerous characteristics, so that contacts can see at a glance and operate with caution.
Only in this way can the storage and transportation of N - (2,6-diethylphenyl) -1,2-benzoyl be maximized to ensure safety and avoid accidents.
