properties and stability

this product is toxic and may cause obvious allergic reactions on skin contact.

storage method

1. this product is toxic. toxic chemicals such as diethylaniline and sodium nitrite are used in the production process. therefore, the equipment must be sealed and production personnel must wear protective gear when operating. reactive materials should be prevented from direct contact with skin or inhalation of dust.

2. packed in an iron drum lined with plastic bags and stored in a cool, dry place away from light. store and transport according to regulations on toxic chemicals.

synthesis method

using n,n-diethylaniline as raw material, it is obtained through nitrosation, reduction and neutralization: the process is as follows: (1) nitrosation: add 150kg water, 35kg n,n-diethylaniline and 72kg to the kettle hydrochloric acid, cool to 0°c. at 0-5°c, add 50% sodium nitrite solution (prepared to 100% 18.5kg). after adding, stir for half an hour and add 6kg of salt. stir for 2h. filter to obtain p-nitroso-n,n-diethylaniline. (2) reduction and neutralization add 150kg water and 11kg hydrochloric acid to the kettle. stir, add 41kg of iron powder, cool to 15°c, and add nitrite at 20-25°c. after the addition is completed, add 5kg of iron powder and stir at 20-25°c for 3 hours. add 7kg of sodium carbonate, stir for 15 minutes, and filter. the filter cake is washed with hot water. add 50kg liquid alkali (30%) and 15kg salt to the filtrate and washing liquid, and let stand for layering. the upper material distillation kettle is distilled under reduced pressure at 120-150°c and a vacuum of 8kpa to collect the fractions to obtain p-amino-n,n-diethylaniline.

purpose

dye intermediates. its hydrochloride and sulfate can be used as color photographic developers.

purpose

metal passivators have two applications in the oil refining industry. (1) substances used to inhibit the catalytic effect of active metal ions (copper, iron, nickel, manganese, etc.) on oil oxidation. it is often used in combination with antioxidants in light fuels such as gasoline, jet fuel, and diesel to improve the stability of the oil and extend the storage period. commonly used ones include n,n’-disalicylidenepropanediamine. (2) in the catalytic cracking of heavy oil, antimony compounds are commonly used as substances used to inhibit the influence of heavy metals (nickel, vanadium, copper, etc.) contained in the oil on the catalyst activity.

properties and stability

keep away from oxides, acids, moisture.

storage method

store in an airtight container and place store in a cool, dry place. stored the place must be locked and the keys must be given to the technical experts and their assistants for safekeeping. storage must be away from oxidizing agents. keep away from water and never store with acidic substances. avoid contact with moisture and water.

synthesis method

none yet

purpose

mainly used as a dehydrating agent for amikacin, glutathione and other drugs, and can also be used for the synthesis of acid anhydrides, aldehydes, ketones, and isocyanates.
