Embodiment Construction

[0017] The production process of N.N-ethylene bisoleic acid amide uses the leftover oil of the oil factory, and takes the rapeseed oil acidified oil as the starting raw material, and produces N.N-ethylene bisoleic acid amide through the following process steps successively. The specific production process yes:

[0018] (1) Esterification section: Add methanol to the acidified rapeseed oil, use solid acid as a catalyst, control the temperature between 90°C and 110°C, control the pressure below 1Kpa, and control the reaction time within 3 to 5 hours to make it happen Esterification reaction, the reaction generates methyl rapeseed, water and glycerin, when the acid value in the reaction process drops to 2, the reaction is terminated, the reaction product is added to hot water for washing, and then dehydration after washing.

[0019] (2) Distillation section: the product obtained in step (1) is continuously distilled under negative pressure, the pressure is -3Kpa, the distillation...

Abstract

The invention relates to a production process for N, N-ethylene bis oleamide. Sulfated rapeseed oil is taken as the initial raw material, and is orderly esterified, distilled, amidated, deodorized, bleached and dehydrated, the esterification is to add methanol into the sulfated rapeseed oil with solid acid as the catalyst to react to generate rapeseed oil methyl ester, the rapeseed oil methyl ester is distilled and then is reacted with ethylene diamine with potassium hydroxide as the catalyst to react to generate N, N-ethylene bis oleamide. The production process realizes the full utilization of the renewable resource, reduces the environmental pollution, can produce the N, N-ethylene bis oleamide with higher quality and content, has low production cost, possesses higher economic value, can also reclaim and circularly utilize the castoff at the same time, has smaller pollution produced during the production and easily treated waste water, can achieve the related national standard, and meets the national policy of sustainable development.

Description

technical field [0001] The invention relates to a fine chemical production process, in particular to a production process for producing N.N-ethylene bisoleic acid amide used in the field of high-grade lubricants or plasticizers by utilizing leftovers produced in the refining process of rapeseed oil. Background technique [0002] At present, N.N-ethylene bisoleic acid amide is used in the production of high-grade lubricants or plasticizers. The existing production process of N.N-ethylene bisoleic acid amide is generally to use refined oil for hydrolysis, distillation, and then Amidation; some companies also use fatty acids for amidation to produce N.N-ethylene bisoleic acid amide. The product produced by the above production process has a low content of N.N-ethylene bisoleic acid amide, its production cost is high, and the pollution generated in the production process is relatively large, the waste water is not easy to treat, and it is difficult to reach the relevant national...
