Storage method:

Store in a cool and ventilated warehouse. Avoid burning and heating. Separate oxidizer boxes to avoid mixed storage. Cover and save. Equipped with corresponding types and quantities of fire extinguishing equipment. The storage area should be equipped with leakage emergency treatment devices and suitable storage materials.

Comprehensive method:

By the reaction of formaldehyde and glycol amine. Heat formic acid in the reaction pot, stir, drop the mixture of formaldehyde and glycol amine, about 1 hour later, the temperature is still maintained at 90-98 ℃, continue to stir for 4 hours. After distillation, the rectified product at 120-130°C (0.53kPa) is collected to obtain N-methyldiolamine with a yield of 85%.

The product obtained by the reaction of methylamine and ethylene oxide. When the temperature is lower than 30°C, add ethylene oxide gas to the 20% methylamine solution until the relative density of the reaction solution reaches 1.025. Stir for 15min, the relative density does not change. Atmospheric pressure methylamine is recovered to 103°C, and the distillate is 119-170°C (4.67kPa) after vacuum distillation. That is the finished product. The output is 72%. Raw material consumption: 950kg/t of ethylene oxide, 870kg/t (40%) of methylamine. In addition, using formaldehyde and cyanoethanol as raw materials, N-methyldiolamine was synthesized by catalytic hydrogenation.

Basic use:

This product is a selective desulfurization and decarbonization agent with high selectivity, low solvent consumption, obvious energy saving effect, and not easy to decompose. Gaseous and gaseous desulfurization purifiers, acid gas absorbents, acid-base control agents, polyurethane foam catalysts, etc. which are widely used in oil fields. Because carbon dioxide in synthetic ammonia can be removed with the participation of activators, the absorption of carbon dioxide in flue gas has become popular in recent years.
