Synthesis method
Place 100 kgOleic acid is put into the reaction kettle, heated and melted, and heated up under stirring. When the material reaches 180 ℃ or so, start ammonia flow. Ammonia gas enters the feed liquid from the bottom of the reactor through the distributor. Rapid stirring enhances the contact between the gas phase and the liquid phase. The by-product water and ammonia gas from the end melon enter the recovery device through the condenser. When the ammonia input amount is200 kg, detect whether there is water in the discharged gas phase. If there is no water in the gas, it is determined that the reaction has reached the end point. Stop nitrogen flow. Discharge while hot and cool to form. Use ethanol as solvent for recrystallization to obtain fine product.
Purpose
This product can be used as a softener and waterproofing agent for chemical fibers. It can also be used as dye, paint dispersant and metal rust inhibitor. Organic intermediates and textile auxiliaries.
