In addition, the stability of 1% 2C12-dodecyl dimethyl amine oxide is quite high. Under normal temperature and pH conditions, its chemical structure is not easy to change. However, under extreme conditions such as strong acid, strong base or high temperature, it may cause changes in its molecular structure and cause damage to its properties. Because of its unique physical and chemical properties, 1% 2C12-dodecyl dimethylamine oxide is widely used in daily chemical, textile, petroleum and many other industries. In daily chemical products, it is often used as a foaming agent, foam stabilizer and thickener to improve the performance of products; in the textile industry, it can be used as a softener and antistatic agent to improve the quality of fabrics; in the petroleum field, it can also be used as an oil displacement agent to enhance crude oil recovery.

The production process of 1% 2C12-dodecyl diethanolamine (DCO) has three methods, each of which is exquisite, and let me tell you one by one. One is the fatty acid method. Take the fatty acid and diethanolamine and put them into the reactor in an appropriate ratio. The kettle needs to be filled with nitrogen to remove air and prevent oxidation. Then it is heated to 180-220 ° C. This temperature can cause the amidation reaction between the two. During the reaction, the stirring should not be stopped to ensure that the materials are in uniform contact. When the reaction is completed, the temperature is lowered, and the crude product can be obtained. After distillation under reduced pressure, impurities are removed, and pure 12-dodecyl diethanolamine is finally obtained. The raw materials for this process are common, and the operation is relatively simple. However, the reaction temperature is quite high and the energy consumption is also large. The second is the fatty nitrile method. Fatty nitrile and diethanolamine are used as raw materials. First, the fatty nitrile and diethanolamine are mixed in proportion and put into the high-pressure reactor. Add a catalyst such as Raney Nickel to seal the kettle body. Hydrogen is introduced to make the pressure in the kettle reach 3-5 MPa, and the temperature is raised to 100-150 ° C. Under this condition, the fatty nitrile undergoes a hydrogenation reaction and combines with diethanolamine to form the target product. After the reaction is completed, the catalyst is filtered and purified by distillation. The reaction conditions of this process are mild, the product purity is high, and high- The third is the ethylene oxide method. Dodecylamine is put into the reactor and ethylene oxide is slowly introduced. The reaction temperature is controlled at 80-120 ° C. During the reaction process, ethylene oxide is ring-opening and dodecylamine is added to generate 12-dodecyl diethanolamine. This process has fast reaction speed and good product quality. However, ethylene oxide has high activity. The operation needs to be cautious. If there is a little carelessness, it is prone to danger.

The husband of DCO has a wide range of uses and is involved in the chemical industry. The change in its price depends on various factors. As far as the raw material is concerned, if the production of its source fluctuates, or the difficulty of obtaining it is different, the price will also change accordingly. And the cost of production and energy consumption are all factors that affect the price. The competition in the market state is also the key. Due to the small number of businesses, the situation of supply and demand affects its price. If the demand exceeds the supply, the price will rise; on the contrary, if the supply exceeds the demand, the price will fall. According to the current situation, the price of 1% 2C12-dodecyl diethanolamine per kilogram is about [X] yuan to [X] yuan. However, this is only an approximate number, and the market conditions change, and the price is also changeable. It may rise or fall according to the market. If a businessperson wants to know the exact price, he should carefully observe the dynamics of the market and consult the industry to understand his situation. And the price may vary from place to place, depending on transportation and taxes. Therefore, if you want to know the truth, you must seek extensive information and be careful.

The upstream industry of 1% 2C12-dodecyl diethanolamide (DCO) is the source of raw material supply. Its key raw materials are lauric acid and diethanolamine.
